SIDACtor Data Book and Design Guide

Product Description

SIDACtor components are solid state crowbar devices designed to protect telecom

equipment during hazardous transient conditions. Capitalizing on the latest in thyristor

advancements, Teccor makes SIDACtor devices with a patented ion implant technology.

This technology ensures effective protection within nanoseconds, up to 5000 A surge

current ratings, and simple solutions for regulatory requirements such as GR 1089,

TIA-968 (formerly known as FCC Part 68), ITU-T K.20, ITU-T K.21, and UL 60950.

Operation

In the standby mode, SIDACtor devices exhibit a high off-state impedance, eliminating

excessive leakage currents and appearing transparent to the circuits they protect. Upon

application of a voltage exceeding the switching voltage (V_S), SIDACtor devices crowbar

and simulate a short circuit condition until the current flowing through the device is either

interrupted or drops below the SIDACtor device’s holding current (I_H). Once this occurs,

SIDACtor devices reset and return to their high off-state impedance.

Advantages

Compared to surge suppression using other technologies, SIDACtor devices offer absolute

surge protection regardless of the surge current available and the rate of applied voltage

(dv/dt). SIDACtor devices:

•

Cannot be damaged by voltage

Eliminate hysteresis and heat dissipation typically found with clamping devices

Eliminate voltage overshoot caused by fast-rising transients

Are non-degenerative

Will not fatigue

Have low capacitance, making them ideal for high-speed transmission equipment

Product Description

Applications

When protecting telecommunication circuits, SIDACtor devices are connected across Tip

and Ring for metallic protection and across Tip and Ground and Ring and Ground for

longitudinal protection. They typically are placed behind some type of current-limiting

device, such as Teccor’s F1250T Telelink slow blow fuse. Common applications include:

•

Central office line cards (SLICs)

T-1/E-1, ISDN, and xDSL transmission equipment

Customer Premises Equipment (CPE) such as phones, modems, and caller ID adjunct

boxes

•

PBXs, KSUs, and other switches

Electrical parameters are based on the following definition of conditions:

•

On state (also referred to as the crowbar condition) is the low impedance condition

reached during full conduction and simulates a short circuit.

Off state (also referred to as the blocking condition) is the high impedance condition prior

to beginning conduction and simulates an open circuit.

C_O

Off-state Capacitance — typical capacitance measured in off state

di/dt

Rate of Rise of Current — maximum rated value of the acceptable rate of

rise in current over time

dv/dt

I_S

Rate of Rise of Voltage — rate of applied voltage over time

Switching Current — maximum current required to switch to on state

Leakage Current — maximum peak off-state current measured at V_DRM

Holding Current — minimum current required to maintain on state

Peak Pulse Current — maximum rated peak impulse current

On-state Current — maximum rated continuous on-state current

Peak One-cycle Surge Current — maximum rated one-cycle AC current

Switching Voltage — maximum voltage prior to switching to on state

Standard Terms and Conditions

Supplier shall not be bound by any term proposed by Buyer in the absence of written agreement to such term signed by an

authorized officer of Supplier.

(1) PRICE:

(A) Supplier reserves the right to change product prices at any time but, whenever practicable, Supplier will give Buyer at

least thirty (30) days written notice before the effective date of any price change. Unless Supplier has specifically

agreed in writing, signed by an authorized officer of Supplier, that a quoted price shall not be subject to change for a

certain time, all products shipped on or after the effective date of a price change may be billed at the new price level.

(B) Whenever Supplier agrees to a modification of Buyer's order (which modification must be in writing and signed by an

authorized officer of Supplier), Supplier reserves the right to alter its price, whether or not such price was quoted

as “firm”.

(C) Prices do not include federal, state or local taxes, now or hereafter enacted, applicable to the goods sold. Taxes will

be added by Supplier to the sales prices whenever Supplier has legal obligation to collect them and will be paid by

Buyer as invoiced unless Buyer provides Supplier with a proper tax exemption certificate.

(2) PRODUCTION: Supplier may, at its sole discretion and at any time, withdraw any catalog item from further production without

notice or liability to Buyer.

(3) INTEREST:

(A) All late payments shall bear interest thirty (30) days after the due date stated on the invoice until paid at the lower of one

and one-half percent per month or the maximum rate permitted by law. All interest becoming due shall, if not paid when

due, be added to principal and bear interest from the due date. At Supplier's option, any payment shall be applied first

to interest and then to principal.

(B) It is the intention of the parties to comply with the laws of the jurisdiction governing any agreement between the

parties relating to interest. If any construction of the agreement between the parties indicates a different right given

to Supplier to demand or receive any sum greater than that permissible by law as interest, such as a mistake in

calculation or wording, this paragraph shall override. In any contingency which will cause the interest paid or

agreed to be paid to exceed the maximum rate permitted by law, such excess will be applied to the reduction of

any principal amount due, or if there is no principal amount due, shall be refunded.

(4) TITLE AND DELIVERY: Title to goods ordered by Buyer and risk of loss or damage in transit or thereafter shall pass to Buyer

upon Supplier's delivery of the goods at Supplier's plant or to a common carrier for shipment to Buyer.

(5) CONTINGENCIES: Supplier shall not be responsible for any failure to perform due to causes reasonably beyond its control.

These causes shall include, but not be restricted to, fire, storm, flood, earthquake, explosion, accident, acts of public enemy,

war rebellion, insurrection, sabotage, epidemic, quarantine restrictions, labor disputes, labor shortages, labor slow downs

and sit downs, transportation embargoes, failure or delays in transportation, inability to secure raw materials or machinery for

the manufacture of its devices, acts of God, acts of the Federal Government or any agency thereof, acts of any state or local

government or agency thereof, and judicial action. Similar causes shall excuse Buyer for failure to take goods ordered by

Buyer, from the time Supplier receives written notice from Buyer and for as long as the disabling cause continues, other than

for goods already in transit or specially fabricated and not readily saleable to other buyers.

Supplier assumes no responsibility for any tools, dies, and other equipment furnished Supplier by Buyer.

(6) LIMITED WARRANTY AND EXCLUSIVE REMEDY: Supplier warrants all catalog products to be free from defects in materials

and workmanship under normal and proper use and application for a period of twelve (12) months from the date code on the

product in question (or if none, from the date of delivery to Buyer.) With respect to products assembled, prepared, or manu-

factured to Buyer's specifications, Supplier warrants only that such products will meet Buyer's specifications upon delivery.

As the party responsible for the specifications, Buyer shall be responsible for testing and inspecting the products for adher-

ence to specifications, and Supplier shall have no liability in the absence of such testing and inspection or if the product

passes such testing or inspection. THE ABOVE WARRANTY IS THE ONLY WARRANTY EXTENDED BY SUPPLIER, AND

IS IN LIEU OF AND EXCLUDES ALL OTHER WARRANTIES AND CONDITIONS, EXPRESSED OR IMPLIED (EXCEPT AS

PROVIDED HEREIN AS TO TITLE), ON ANY GOODS OR SERVICES SOLD OR RENDERED BY SUPPLIER, INCLUDING

ANY IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THIS WARRANTY

WILL NOT CREATE WARRANTY COVERAGE FOR ANY ITEM INTO WHICH ANY PRODUCT SOLD BY SUPPLIER MAY

HAVE BEEN INCORPORATED OR ADDED.

SUPPLIER'S ENTIRE LIABILITY AND BUYER'S EXCLUSIVE REMEDY UNDER THIS WARRANTY SHALL BE, AT

SUPPLIER'S OPTION, EITHER THE REPLACEMENT OF, REPAIR OF, OR ISSUANCE OF CREDIT TO BUYER'S

ACCOUNT WITH SUPPLIER FOR ANY PRODUCTS WHICH ARE PROPERLY RETURNED BY BUYER DURING THE

WARRANTY PERIOD. All returns must comply with the following conditions:

SIDACtor Data Book and Design Guide

Standard Terms and Conditions

(A) Supplier is to be promptly notified in writing upon discovery of defects by Buyer.

(B) Buyer must obtain a Return Material Authorization (RMA) number from the Supplier prior to returning product.

(C) The defective product is returned to Supplier, transportation charges prepaid by Buyer.

(D) Supplier's examination of such product discloses, to its satisfaction, that such defects have not been caused by

misuse, neglect, improper installation, repair, alteration, or accident.

(E) The product is returned in the form it was delivered with any necessary disassembly carried out by Buyer at Buyer's

expense.

IN NO EVENT SHALL SUPPLIER, OR ANYONE ELSE ASSOCIATED IN THE CREATION OF ANY OF SUPPLIER'S

PRODUCTS OR SERVICES, BE LIABLE TO BUYER FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES OF ANY

NATURE INCLUDING LOSS OF PROFITS, LOSS OF USE, BUSINESS INTERUPTION, AND THE LIKE. BUYER

ACKNOWLEDGES THAT THE ABOVE WARRANTIES AND LIMITATIONS THEREON ARE APPROPRIATE AND

REASONABLE IN EFFECTUATING SUPPLIER'S AND BUYER'S MUTUAL INTENTION TO CONDUCT AN EFFICIENT

TRANSACTION AT PRICES MORE ADVANTAGEOUS TO BUYER THAN WOULD BE AVAILABLE IN THE PRESENCE

OF OTHER WARRANTIES AND ASSURANCES.

(7) PATENTS: Buyer shall notify Supplier in writing of any claim that any product or any part of use thereof furnished under this

agreement constitutes an infringement of any U.S. patent, copyright, trade secret, or other proprietary rights of a third party.

Notice shall be given within a reasonable period of time which should in most cases be within ten (10) days of receipt by

Buyer of any letter, summons, or complaint pertaining to such a claim. At its option, Supplier may defend at its expense any

action brought against Buyer to the extent that it is based on such a claim. Should Supplier choose to defend any such claim,

Supplier may fully participate in the defense, settlement, or appeal of any action based on such claim.

Should any product become, or in Supplier's opinion be likely to become, the subject of an action based on any such

claim, Supplier may, at its option, as the Buyer's exclusive remedy, either procure for the Buyer the right to continue

using the product, replace the product or modify the product to make it noninfringing. IN NO EVENT SHALL SUPPLIER

BE LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL DAMAGES BASED ON ANY CLAIM OF INFRINGEMENT.

Supplier shall have no liability for any claim based on modifications of a product made by any person or entity other than

Supplier, or based on use of a product in conjunction with any other item, unless expressly approved by Supplier.

Supplier does not warrant goods against claims of infringement which are assembled, prepared, or manufactured to

Buyer's specifications.

(8) NON-WAIVER OF DEFAULT: Each shipment made under any order shall be treated as a separate transaction, but in the

event of any default by Buyer, Supplier may decline to make further shipments without in any way affecting its rights under

such order. If, despite any default by Buyer, Supplier elects to continue to make shipments, its action shall not constitute a

waiver of that or any default by Buyer or in any way affect Supplier's legal remedies for any such default. At any time, Sup-

plier's failure to exercise any right to remedy available to it shall not constitute a waiver of that right or remedy.

(9) TERMINATION: If the products to be furnished under this order are to be used in the performance of a Government contract

or subcontract, and the Government terminates such contract in whole or part, this order may be canceled to the extent it

was to be used in the canceled portion of said Government contract and the liability of Buyer for termination allowances shall

be determined by the then applicable regulations of the Government regarding termination of contracts. Supplier may cancel

any unfilled orders unless Buyer shall, upon written notice, immediately pay for all goods delivered or shall pay in advance

for all goods ordered but not delivered, or both, at Supplier's option.

(10) LAW: The validity, performance and construction of these terms and conditions and any sale made hereunder shall be gov-

erned by the laws of the state of Texas.

(11) ASSIGNS: This agreement shall not be assignable by either Supplier or Buyer. However, should either Supplier or Buyer be

sold or transferred in its entirety and as an ongoing business, or should Supplier or Buyer sell or transfer in its entirety and as

an ongoing concern, any division, department, or subsidiary responsible in whole or in part for the performance of this Agree-

ment, this Agreement shall be binding upon and inure to the benefit of those successors and assigns of Supplier, Buyer, or

such division, department, or subsidiary.

(12) MODIFICATION OF STANDARD TERMS AND CONDITIONS: No attempted or suggested modification of or addition to any

of the provisions upon the face or reverse of this form, whether contained or arising in correspondence and/or documents

passing between Supplier and Buyer, in any course of dealing between Supplier or Buyer, or in any customary usage preva-

lent among businesses comparable to those of Supplier and/or Buyer, shall be binding upon Supplier unless made and

agreed to in writing and signed by an officer of Supplier.

(13) QUANTITIES: Any variation in quantities of electronic components, or other goods shipped over or under the quantities

ordered (not to exceed 5%) shall constitute compliance with Buyer's order and the unit price will continue to apply.

MicroCapacitance (MC) SC SIDACtor Device

The DO-214AA SC MC SIDACtor series is intended for applications sensitive to load

values. Typically, high speed connections require a lower capacitance. C_Ovalues for the

MicroCapacitance device are 40% lower than a standard SC part.

This MC SIDACtor series is used to enable equipment to meet various regulatory

requirements including GR 1089, IEC 60950, UL 60950, and TIA-968 (formerly known as

FCC Part 68). Contact factory regarding ITU K.20, K.21, and K.45.

SIDACtor Data Book and Design Guide

High Surge Current (D-rated) SIDACtor Device

DO-214AA SIDACtor solid state protection devices with a D surge rating protect

telecommunications equipment such as modems, line cards, fax machines, and other CPE.

These SIDACtor devices withstand simultaneous surges incurred in GR 1089 lightning

tests. (See "First Level Lightning Surge Test" on page 4-5.) Surge ratings are twice that of a

device with a C surge rating. This allows a discrete surface mount version of Teccor’s

patented “Y” configuration. (US Patent 4,905,119)

SIDACtor devices are used to enable equipment to meet various regulatory requirements

including GR 1089, ITU K.20, K.21 and K.45, IEC 60950, UL 60950, and TIA-968 (formerly

known as FCC Part 68).

SIDACtor Data Book and Design Guide

Multiport SIDACtor Device

The multiport line protector is an integrated multichip solution for protecting multiple

twisted pair from overvoltage conditions. Based on a six-pin surface mount SOIC

package, it is equivalent to four discrete DO-214AA or two TO-220 packages. Available

in surge current ratings up to 500 A, the multiport line protector is ideal for densely

populated, high-speed line cards that cannot afford PCB inefficiencies or the use of

series power resistors.

overvoltage conditions. Based on a six-pin surface mount SOIC package, it is

equivalent to four discrete DO-214AA or two TO-220 packages. Available in surge

current ratings up to 500 A, the multiport line protector is ideal for densely populated

line cards that cannot afford PCB inefficiencies or the use of series power resistors.

multiple twisted pair from overvoltage conditions. Based on a six-pin SOIC package, it

is equivalent to four discrete DO-214AA packages. Available in surge current ratings

up to 500 A for a 2x10 µs event, the multiport line protector is ideal for densely

populated line cards that cannot afford PCB inefficiencies or the use of series power

resistors.

Teccor’s six-pin Battrax devices are constructed using four SCRs and four gate diodes.

The SCRs conduct when a voltage that is more negative than -V (and/or more

) is applied to the cathode (Pins 1 and 3) of the SCR. During

REF

conduction, the SCRs appear as a low-resistive path which forces all transients to be

TeleLink Fuse

The TeleLink Surface Mount (SM) surge resistant fuse offers circuit protection without

requiring a series resistor. When used in conjunction with the SIDACtor Transient Voltage

Suppressor (TVS), the TeleLink SM fuse and the SIDACtor TVS provide a complete

regulatory-compliant solution for standards such as GR 1089, TIA-968 (formerly known as

FCC Part 68), UL 60950, and ITU K.20 and K.21. No series resistor is required for the

F1250T and F1251T to comply with these standards.

Customer Premises Equipment (CPE)

CPE is defined as any telephone terminal equipment which resides at the customer’s site

and is connected to the Public Switched Telephone Network (PSTN). Telephones, modems,

caller ID adjunct boxes, PBXs, and answering machines are all considered CPE.

Protection Requirements

CPE should be protected against overvoltages that can exceed 800 V and against surge

currents up to 100 A. In Figure 3.1 through Figure 3.6, SIDACtor devices were chosen

because their associated peak pulse current (I_PP) rating is sufficient to withstand the

lightning immunity test of TIA-968 (formerly known as FCC Part 68) without the additional

use of series line impedance. Likewise, the fuse shown in Figure 3.1 through Figure 3.6

was chosen because the amps²time (I²t) rating is sufficient to withstand the lightning

immunity tests of TIA-968 without opening, but low enough to pass UL power cross

conditions.

The following regulatory requirements apply:

•

TIA-968 (formerly known as FCC Part 68)

UL 60950

All CPE intended for connection to the PSTN must be registered in compliance with

TIA-968. Also, because the National Electric Code mandates that equipment intended for

connection to the telephone network be listed for that purpose, consideration should be

given to certifying equipment with an approved safety lab such as Underwriters

Laboratories.

CPE Reference Circuits

Figure 3.1 through Figure 3.6 show examples of interface circuits which meet all applicable

regulatory requirements for CPE. The P3100SB and P3100EB are used in these circuits

because the peak off-state voltage (V_DRM) is greater than the potential of a Type B ringer

superimposed on a POTS (plain old telephone service) battery.

150 V_RMSꢀꢁ2 + 56.6 V_PK= 268.8 V_PK

Note that the circuits shown in Figure 3.1 through Figure 3.6 provide an operational solution

for TIA-968 (formerly known as FCC Part 68). However TIA-968 allows CPE designs to

pass non-operationally as well.

For a non-operational solution, coordinate the I_PPrating of the SIDACtor device and the I²t

rating of the fuse so that (1) both will withstand the Type B surge, and (2) during the Type A

surge, the fuse will open. (See Table 5.1, Surge Rating Correlation to Fuse Rating on page

5-8.)

Note: For alternative line interface protection circuits, see "Regulatory Compliant Solutions"

on page 4-34.

High Speed Transmission Equipment

High speed transmission equipment encompasses a broad range of transmission protocols

such as T1/E1, xDSL, and ISDN. Transmission equipment is located at the central office,

customer premises, and remote locations.

Protection Requirements

Transmission equipment should be protected against overvoltages that can exceed 2500 V

and surge currents up to 500 A. In Figure 3.7 through Figure 3.17, SIDACtor devices were

chosen because their associated peak pulse current (I_PP) rating is sufficient to withstand the

lightning immunity tests of GR 1089 without the additional use of series line impedance.

Likewise, the fuse shown in Figure 3.7 through Figure 3.17 was chosen because the

amps²time (I²t) rating is sufficient to withstand the lightning immunity tests of GR 1089, but

low enough to pass GR 1089 current limiting protector test and power cross conditions

(both first and second levels).

The following regulatory requirements apply:

•

TIA-968 (formerly known as FCC Part 68)

GR 1089-CORE

ITU-T K.20/K.21

UL 60950

Most transmission equipment sold in the US must adhere to GR 1089. For Europe and

other regions, ITU-T K.20/K.21 is typically the recognized standard.

ADSL Circuit Protection

Asymmetric Digital Subscriber Lines (ADSLs) employ transmission rates up to 6.144 Mbps

from the Central Office Terminal (COT) to the Remote Terminal (RT) and up to 640 kbps

from the RT to the COT at distances up to 12,000 feet. (Figure 3.7)

Protection Circuitry

Longitudinal protection was not used at either the ADSL Transceiver Unit – Central Office

(ATU-C) interface or the ADSL Transceiver Unit – Remote (ATU-R) interface due to the

absence of earth ground connections. (Figure 3.8) In both instances, the P3500SC MC

SIDACtor device and the F1250T TeleLink fuse provide metallic protection. For ATUs not

isolated from earth ground, reference the HDSL protection topology.

Component Selection

The P3500SC MC SIDACtor device and F1250T TeleLink fuse were chosen to protect the

ATUs because both components meet GR 1089 surge immunity requirements without the

use of additional series resistance. Although the P3100 series SIDACtor device may be

used to meet current ANSI specifications, Teccor recommends the P3500 series to avoid

interference with the 20 V_P-Px DSL signal on a 150 V rms ringing signal superimposed on a

56.5 V battery.

HDSL Circuit Protection

HDSL (High-bit Digital Subscriber Line) is a digital line technology that uses a 1.544 Mbps

(T1 equivalent) transmission rate for distances up to 12,000 feet, eliminating the need for

repeaters. The signaling levels are a maximum of ±2.5 V while loop powering is typically

under 190 V. (Figure 3.9)

Longitudinal protection is required at both the HDSL Transceiver Unit – Central Office

connection used with loop powering. Two P2300SC MC SIDACtor devices provide

overvoltage protection and two F1250T TeleLink fuses (one on Tip, one on Ring) provide

overcurrent protection. (Figure 3.10) For the transceiver side of the coupling transformer,

additional overvoltage protection is provided by the P0080SA SIDACtor device. The

longitudinal protection on the primary coil of the transformer is an additional design

consideration for prevention of EMI coupling and ground loop issues.

Component Selection

The P2300SC MC SIDACtor device and the F1250T TeleLink fuse were chosen because

both components meet GR 1089 surge immunity requirements without the use of additional

series resistance. The P2300SC MC voltage rating was selected to ensure loop powering

up to 190 V. For loop powering greater than 190 V, consider the P2600SC MC. The

P0080SA MC SIDACtor device was chosen to eliminate any sneak voltages that may

appear below the voltage rating of the P2300SC MC.

ISDN Circuit Protection

Integrated Services Digital Network (ISDN) circuits require protection at the Network

Termination Layer 1 (NT1) U-interface and at the Terminating Equipment (TE) or

Terminating Adapter (TA) S/T interface. Signal levels at the U-interface are typically ±2.5 V;

however, with sealing currents and maintenance loop test (MLT) procedures, voltages

approaching 150 V rms can occur. (Figure 3.11)

The “SC MC” SIDACtor devices and F1250T TeleLink fuse were chosen because these

series resistance. An MC is chosen to reduce degradation of data rates. The P2600SC MC

voltage rating was selected to ensure coordination with MLT voltages that can approach

150 V rms. The voltage rating of the P0640SC MC was selected to ensure coordination with

varying signal voltages.

Pair Gain Circuit Protection

A digital pair gain system differs from an ISDN circuit in that ring detection, ring trip, ring

forward, and off-hook detection are carried within the 64 kbps bit stream for each channel

rather than using a separate D channel. The pair gain system also uses loop powering from

10 V up to 145 V with a typical maximum current of 75 mA. (Figure 3.13)

devices provide overvoltage protection and two F1250T TeleLink fuses (one on Tip, one on

is compliant with TIA-968 regulations, Section 4.4.5.2, “Connections with protection paths

to ground.” These regulations state:

Approved terminal equipment and protective circuitry having an

intentional dc conducting path to earth ground for protection purposes at

60 Hz voltage source applied between the following points:

and Ring-1, E&M leads and auxiliary leads

b. Earth grounding connections

The voltage shall be gradually increased from zero to 120 V rms for

The peak voltage for 120 V rms is 169.7 V. The minimum stand-off voltage for the P1800 is

170 V, therefore, the P1800SC MC will pass the test in Section 4.4.5.2 by not allowing

10 mA of current to flow during the application of this test voltage.

For the transceiver side of the coupling transformer, additional overvoltage protection is

shown in Figure 3.17 using the P0300SA SIDACtor device. When an earth ground

connection is not used, only metallic protection is required. Metallic protection is satisfied

using a single P0640SC MC SIDACtor device across Tip and Ring and a single F1250T

TeleLink fuse on either Tip or Ring.

Additional T1 Design Considerations

A T1 application can be TIA-968 approved as two different possible device types. An XD

device means an external CSU is used and the unit does not have to meet the

TIA-968 environmental test conditions, but it must connect only behind a separately

registered DE device. This XD equipment does not have to meet the T1 pulse template

requirements. If not classified as an XD device, then typically the application must adhere to

TIA-968 environmental test conditions.

T3 Protection

The capacitance across the pair of wires = (D1 || D2) + P0640EC/SC. The diode

capacitance is approximately (10 pF || 10 pF) 20 pF. Then adding the capacitive effect of

the P0640EC/SCMC, which is typically 60 pF, the total capacitance across the pair of wires

is approximately 15 pF. The MUR 1100E diodes are fast-switching diodes that will exhibit

this level of capacitance. MURS160T3 is a surface mount equivalent. (Figure 3.18)

Analog Line Cards

Given that line cards are highly susceptible to transient voltages, network hazards such as

lightning and power cross conditions pose a serious threat to equipment deployed at the

central office and in remote switching locations. To minimize this threat, adequate levels of

protection must be incorporated to ensure reliable operation and regulatory compliance.

Protection Requirements

When designing overvoltage protection for analog line cards, it is often necessary to

provide both on-hook (relay) and off-hook (SLIC) protection. This can be accomplished in

two stages, as shown in Figure 3.20.

maximum voltage rating of the SLIC to be protected.

V

_DRM> V_REF

V_Sꢀ?ꢀV_{SLIC Breakdown}

This criterion can be accomplished in a variety of different ways. For applications using an

external ring generator and a fixed battery voltage, two P0641S_ SIDACtor devices

(P0721S_, P0901S_, or P1101S_ depending on the value of V_REF) are used — one Tip to

Ground, one Ring to Ground. For applications using a ring-generating SLIC such as AMD’s

Am79R79, the B1XX0C_ or B1XX1U_ can be used.

I_PPSelection

The I of the SIDACtor device must be greater than or equal to the maximum available

PP

surge current (I_{PK(available)}) of the applicable regulatory requirements. Calculate the maximum

available surge current by dividing the peak surge voltage supplied by the voltage generator

(V_PK) by the total circuit resistance (R_TOTAL). The total circuit resistance is determined by

adding the source resistance (R_S) of the surge generator to the series resistance in front of

the SIDACtor device on Tip and Ring (R_TIPand R_RING).

Figure 3.21 shows the use of Teccor’s “SC” rated SIDACtor devices and the F1250T

P2000SC, specifically designed to protect Agere Systems (formerly Lucent

Microelectronics) Line Card Access Switch (LCAS), provide on-hook protection. Two

P0641SCs provide off-hook protection. Any additional series resistance is absent because

the “C” series SIDACtor device and F1250T TeleLink fuse are designed to withstand

GR 1089 surges without the aid of additional components such as line feed resistors and

PTCs.

within the surge current rating of the SA-rated SIDACtor device and Battrax. The diode

bridge shunts all positive voltages to Ground, and the B1100CC shunts all negative

In Figure 3.26 an application that requires 50 ꢂ Line Feed Resistors (LFR) uses one

B1160CC and two EDF1BS diode bridges in place of multiple SLIC protectors. The

overshoot caused by the diode bridge must be considered; however, with this approach it is

imperative that the sum of the loop currents does not exceed the Battrax’s holding current.

In the application shown in Figure 3.26, each loop current would have to be limited to

PBXs, KSUs, and PABXs contain line cards that support various transmission protocols

such as ISDN, T1/E1, HDSL, and ADSL (Figure 3.31). PBXs also have features such as a

POTS (plain old telephone service) pull-through which allows stations to have outside line

access in the event of power failure. All incoming lines to the PBX are subject to

environmental hazards such as lightning and power cross.

CATV Equipment

As cable providers enter the local exchange market, protection of CATV (Community

Antenna TV) equipment becomes even more critical in order to ensure reliable operation of

equipment and uninterrupted service.

Protection Requirements

CATV line equipment should be able to withstand overvoltages that exceed 6000 V and

surge currents up to 5000 A. CATV station protectors should be able to withstand

overvoltages that exceed 5000 V and surge currents up to 1000 A. The SIDACtor devices

illustrated in Figure 3.32 through Figure 3.35 meet these requirements.

Primary Protection

Primary telecommunications protectors must be deployed at points where exposed twisted

pairs enter an office building or residence. This requirement is mandated in North America

by the National Electric Code (NEC) to protect end users from the hazards associated with

lightning and power cross conditions.

Primary protection is provided by the local exchange carrier and can be segregated into

three distinct categories:

•

Station protection — typically associated with a single twisted pair

Building entrance protection — typically associated with multiple (25 or more) twisted

pair

•

Central office protection — typically associated with numerous twisted pair feeding into a

switch

Station protectors provide primary protection for a single-dwelling residence or office. The

station protector is located at the Network Interface Unit (NIU), which acts as the point of

demarcation, separating the operating company’s lines from the customer’s.

Building entrance protection is accomplished by installing a multi-line distribution panel with

integrated overvoltage protection. These panels are normally located where multiple twisted

pairs enter a building.

A five-pin protection module plugged into a Main Distribution Frame (MDF) provides Central

and Remote Office protection. Like station and building entrance protection, the MDF is

located where exposed cables enter the switching office.

Teccor also offers a full line of five-pin protectors. For further details, contact factory at

protectionsystems@teccor.com or +1 972-580-7777.

Protection Requirements

Station protectors must be able to withstand 300 A 10x1000 surge events. The building

entrance protectors and CO protectors must be able to withstand 100 A 10x1000 surge

events. Figure 3.36 shows building entrance protector and CO protector asymmetrical

solutions. Figure 3.37 shows building entrance protector and CO protector balanced

solutions.

The following regulatory requirements apply:

Figure 3.36 and Figure 3.37 show different configurations used in primary protection. Note

that the peak off-state voltage (V_DRM) of any device intended for use in primary protection

applications should be greater than the potential of a Type B ringer superimposed on a

POTS (plain old telephone service) battery.

Secondary Protection

Secondary protectors (stand alone units or integrated into strip protectors and UPSs) are

adjunct devices used to enhance the protection level of customer premise equipment

(CPE). Due to the inadequate level of protection designed into CPE, secondary protectors

often are required to prevent premature failure of equipment exposed to environmental

hazards (Figure 3.38).

Figure 3.38 also shows an example of an interface design for a secondary protector. The

P3203AB SIDACtor device is used because the peak off-state voltage (V_DRM) is greater

than the potential of a Type B ringer signal superimposed on the POTS (plain old telephone

service) battery.

150 V_RMSꢀꢁ2 + 56.6 V_PK= 268.8 V_PK

Coordination between the station protector and the secondary protector occurs due to the

line impedance between the two devices. The line impedance helps ensure that the primary

protector will begin to conduct while the secondary protector limits any of the let-through

voltage to within the V_Srating of the SIDACtor device.

Triac Protection

Thyristors

Damage can occur to a thyristor if the thyristor’s repetitive peak off-state voltage is

exceeded. A thyristor’s repetitive peak off-state voltage may be exceeded due to dirty AC

power mains, inductive spikes, motor latch up, and so on.

Thyristor Reference Circuit

Figure 3.40 and Figure 3.41 show two different methods of protecting a triac. In Figure 3.40,

a SIDACtor device is connected from MT2 to the gate of the triac. When the voltage applied

to the triac exceeds the SIDACtor device’s V_DRM, the SIDACtor device turns on, producing a

gate current which turns the triac on.

4 Regulatory

Requirements

Due to the enormous cost of interrupted service and failed network equipment, telephony

service providers have adopted various specifications to help regulate the reliability and

performance of the telecommunications products that they purchase. In Europe and much

of the Far East, the most common standards are ITU-T K.20 and K.21. In North America,

most operating companies base their requirements on GR 1089, TIA-968 (formerly known

as FCC Part 68), and UL 60950.

Note: This section is a paraphrase of existing documents and does not cover the listed

regulatory requirements in their entirety. This information is intended to be used only

GR 1089–Core

In the United States, the telecommunication network is primarily operated by the Regional

Bell Operating Companies (RBOC) who follow the standards set by GR 1089 or a derivative

thereof. GR 1089–Core (often referred to as GR 1089), “Electromagnetic Compatibility and

Electrical Safety Generic Criteria for Network Telecommunications Equipment,” covers the

requirements for telecommunications equipment connected to the outside world through

twisted pair. It also addresses the criteria for protection from lightning and AC power cross

disturbances.

Because twisted pair are metallic conductors exposed to lightning and AC power faults,

GR 1089 documents the requirements to be met by manufacturers of public switched

telephone network (PSTN) equipment to ensure safe and reliable operation.

The criteria for these standards are based on transient conditions at exposed sites, such as

remote facilities, central offices, and customers’ premises where operating companies

provide some type of primary voltage protection to limit transient voltages to 1000 V peak

for surge conditions and 600 V rms for power cross conditions.

All network equipment shall be listed by a Nationally Recognized Testing Laboratory

(NRTL) if the equipment is directly powered by Commercial AC. Network equipment located

on customer premises shall be listed by NRTL.

In conjunction with primary voltage protectors, operating companies also may incorporate

fuse links if there is the possibility of exposing the twisted pair to outside power lines. These

fuse links are equivalent to 24- or 26-gauge copper wire and are coordinated with the

current-carrying capacity of the voltage protector.

The last element of protection that may be provided by the operating company are current

limiters which, if provided, are found on the line side of the network equipment after the

primary voltage protection device. These current limiters typically come in the form of heat

coils and have a continuous rating of 350 mA.

Requirements

Equipment required to meet GR 1089 must be designed to pass:

•

Both First and Second Level Lightning Surge and AC Power Fault Tests

Current Limiter Test

Short Circuit Test

A minimum of three units are tested for each of the operating states in which the Equipment

Under Test (EUT) may be expected to function — idle, transmit, receive, on-hook, off-hook,

talking, dialing, ringing, and testing. Table 4.1 and Table 4.2 show test connections, and

Figure 4.1 shows the connection appearances.

GR 1089–Core

AC Power Fault Test is that the EUT may be damaged, but it may not become a fire,

fragmentation, or electrical safety hazard. Passing criteria for the Current Limiter Test is that

the EUT may be damaged but it may not exceed the acceptable time/current criteria (that is,

cannot cause the wiring simulator as shown in Figure 4.2 to open) nor become a fire,

fragmentation, or electrical safety hazard.

The indicator used in measuring fire, fragmentation, and electrical safety hazards is a

bleached, untreated cotton cheesecloth wrapped around the EUT. Compliance with testing

is determined by the absence of ignition, charring, and the ejection of molten material or

fragments.

First Level Lightning Surge Test

To pass the First Level Lightning Surge Test, the EUT must be undamaged and continue to

operate properly after the stress is applied. This is referred to as passing “operationally.”

Table 4.3 presents the conditions for the First Level inter-building criteria. Applicants have

the option to submit their equipment to meet surges 1, 2, 4, and 5 or surges 3, 4, and 5.

Second Level Lightning Surge Test

The Second Level Lightning Surge Test, presented in Table 4.5, does not require the EUT

to pass operationally, but GR 1089 does require that the EUT not become a fire,

fragmentation, or electrical safety hazard. This is referred to as passing “non-operationally.”

AC Power Fault Tests

Power companies and telephone operating companies often share telephone poles and

trenches; therefore, network equipment is often subjected to the voltages seen on power

lines. If direct contact between the telephone line and the primary power line occurs, the

operating company’s network equipment may see as much as 600 V rms for five seconds,

by which time the power company’s power system should clear itself. If direct contact

occurs with the secondary power line, voltages will be limited to 277 V rms; however, these

voltages may be seen indefinitely because the resultant current may be within the operating

range of the power system, and the power system will not reset itself.

Another risk involved with power lines is indirect contact. Because of the large magnetic

fields created by the currents in the power lines, large voltages may be induced upon phone

lines via electro-magnetic coupling. In this instance voltages should be limited to

1000 V peak and 600 V rms using primary protectors, while the current will be limited by the

current-carrying capacity of the 24-gauge wire.

fuse rating.

6. Intra-building, second level lower fault test uses test condition 1 only. The applied voltage is at 120 V rms only.

Second Level AC Power Fault for Customer Premises Equipment

For customer premises equipment, the EUT is tested to the conditions presented in

Table 4.8 and connected to a circuit equivalent to that shown in Figure 4.2. During this test,

the wiring simulator cannot open. For equipment that uses premises type of wiring, the

wiring simulator is a 1.6 A Type MDQ fuse from Bussman. For equipment that is connected

by cable, the wiring simulator is a piece of 26-gauge copper wire.

Current Limiting Protector Test

The purpose of the Current Limiting Protector Test, presented in Table 4.9, is to determine if

the EUT allows an excessive amount of current flow under power fault conditions. During

this test, the EUT is connected to a circuit equivalent to that shown in Figure 4.2 with a

1.6 A Type MDQ fuse from Bussman used as the wiring simulator. If the EUT draws enough

current to open the fuse, then the acceptable time/current criteria have not been met, and

external current limiting protectors must be specified for use with that equipment in the

Short-circuit Test

In addition to the AC Power Fault and Current Limiter Tests, equipment must also pass a

Short-circuit Test to comply with GR 1089. During this test, a short-circuit condition is

applied to the following Tip and Ring appearances for 30 minutes while the EUT is powered

and under operating conditions:

•

Tip-to-Ring, Tip-to-Ground with Ring open circuit

Ring-to-Ground with Tip open circuit

Tip- and Ring-to-Ground simultaneously for 30 minutes

At no time will the short circuit exceed 1 ꢂ. For equipment with more than one twisted pair,

the short circuit is applied to all twisted pair simultaneously. To comply with the short circuit

test, the EUT must function normally after the short-circuit condition is removed, and a fire

hazard may not be present. The equipment shall not require manual intervention to restore

service.

ITU-T K.20 and K.21

Although the International Telecommunication Union (ITU) does not have the authority to

legislate that organizations follow their recommendations, their standards are recognized

throughout Europe and the Far East.

ITU-T, the Telecommunication Standardization Sector of the ITU, developed fundamental

testing methods that cover various environmental conditions to help predict the survivability

of network and customer-based switching equipment. The testing methods cover the

following conditions:

•

Surges due to lightning strikes on or near twisted pair and plant equipment (excluding a

direct strike)

Short-term induction of AC voltage from adjacent power lines or railway systems

Direct contact between telecommunication lines and power lines (often referred to as

AC power cross)

•

Two ITU-T standards apply for most telecommunications equipment connected to the

network:

•

ITU-T K.20

ITU-T K.21

ITU-T K.20 is primarily for switching equipment powered by the central office; however, for

complex subscriber equipment, test administrators may choose either K.20 or K.21,

depending on which is deemed most appropriate.

Note: Both standards are intended to address equipment reliability versus equipment

safety. For specific concerns regarding equipment safety, research and follow

national standards for each country in which the equipment is intended for use.

K.21 covers telecommunication equipment installed in customer premises. Equipment

submitted under these requirements must meet one of two levels: basic or enhanced.

Guidelines for determining under which level the equipment under test (EUT) falls can be

found in ITU-T K.11, but note that the final authority rests with the test administrator.

ITU-T K.44 describes the test conditions used in K.20 and K.21.

ITU-T defines the following acceptance criteria:

•

Criterion A states that equipment shall withstand the test without damage and shall

operate properly after the test. It is not required to operate correctly during the test.

Criterion B states that a fire hazard shall not occur as a result of the tests. Any damage

shall be confined to a small part of the equipment.

•

Table 4.10 shows the lightning surge test conditions for ITU K.20. Figure 4.3 shows the

connection schematic for the lightning surge tests. Table 4.11 shows the power cross test

conditions for ITU K.20. Figure 4.4 shows the connection schematic for the power cross

tests. Table 4.12 and Table 4.13 show the same test conditions respectively for ITU K.21.

TIA-968 (formerly known as FCC Part 68)

TIA-968 applies to all terminal equipment connected to the Public Switched Telephone

Network (PSTN) and holds the “rule of law” by congressional order.

The purpose of TIA-968 is to provide a set of uniform standards to protect the telephone

network from any damage or interference caused by the connection of terminal equipment.

This standard includes environmental simulations such as vibration tests, temperature and

humidity cycling, drop tests and tests for hazardous voltages and currents, as well as tests

for signal power levels, line balance, on-hook impedance, and billing protection. All these

standards must be met before and after the environmental tests are applied.

Overvoltage Test

TIA-968 compliant equipment must undergo an overvoltage test that includes a Type A and

Type B Metallic Voltage Surge and a Type A and Type B Longitudinal Voltage Surge. These

surges are part of the environmental simulation, and although a provision does allow the

EUT to reach an open circuit failure mode during the Type A tests, failures must:

1. Arise from an intentional design that will cause the phone to be either disconnected from

the public network or repaired rapidly

2. Be designed so that it is substantially apparent to the end user that the terminal

equipment is not operable

A common example of an acceptable failure would be an open circuit due to an open

connection on either Tip or Ring.

For Type B surges, equipment protection circuitry is not allowed to fail. The EUT must be

designed to withstand Type B surges and continue to function in all operational states.

Metallic Voltage Surge

The Type A and Type B Metallic Voltage Surges are applied in both the positive and

negative polarity across Tip and Ring during all operational states (on-hook, off-hook,

ringing, and so on). The Type A surge is an 800 V, 100 A peak surge while the Type B

surge is a 1000 V, 25 A peak surge, as presented in Table 4.14.

SIDACtor Data Book and Design Guide

TIA-968 (formerly known as FCC Part 68)

Longitudinal Voltage Surge

The Type A and Type B Longitudinal Voltage Surges are applied in both positive and

negative polarity during all operational states. The Type A surge is a 1500 V, 200 A peak

surge applied to the EUT with Tip and Ring tied together with respect to Ground. The

Type B Longitudinal Voltage Surge is a simultaneous surge in which 1500 V and 37.5 A are

applied concurrently to Tip with respect to Ground and Ring with respect to Ground, as

presented in Table 4.14.

Note: Type B surge requirements guarantee only a minimum level of surge protection. For

long term reliability of terminal equipment, consideration should be given to

complying with Type A surges operationally.

On-hook Impedance Limitations

Another important aspect of TIA-968 is on-hook impedance, which is affected by transient

protection. On-hook impedance is analogous to the leakage current between Tip and Ring,

and Tip, Ring, and Ground conductors during various on-hook conditions. "On-hook

Impedance Measurements" (next paragraph) outlines criteria for on-hook impedance and is

listed as part of the Ringer Equivalent Number (REN). The REN is the largest of the unitless

quotients not greater than five; the rating is specified as the actual quotient followed by the

letter of the ringer classification (for example, 2B).

On-hook Impedance Measurements

On-hook impedance measurements are made between Tip and Ring and between Tip and

Ground and Ring and Ground. For all DC voltages up to and including 100 V, the DC

resistance measured must be greater than 5 Mꢂ. For all DC voltages between 100 V and

200 V, the DC resistance must be greater than 30 kꢂ. The REN values are then determined

by dividing 25 Mꢂ by the minimum measured resistance up to 100 V and by dividing

150 kꢂ by the minimum measured resistance between 100 V and 200 V.

On-hook impedance is also measured during the application of a simulated ringing signal.

This consists of a 40 V rms through 150 V rms ringer signal at frequencies ranging from

15.3 Hz to 68 Hz superimposed on a 56.5 V dc for a class “B” ringer. During this test, the

total DC current may not exceed 3 mA. In addition, the minimum DC resistance measured

between Tip and Ring must be greater than 1600 ꢂ, while the DC resistance measured

between the Tip and Ring conductors and Ground must be greater than 100 kꢂ. The REN

values for the simulated ringing test are determined by dividing the maximum DC current

flowing between Tip and Ring by 0.6 mA, and by dividing 8000 ꢂ by the minimum

impedance value measured.

UL 60950 3rd Edition (formerly UL 1950, 3rd edition)

UL 60950 3rd Edition

(formerly UL 1950, 3rd edition)

After the divestiture of the AT&T/Bell system, the National Electric Code (NEC)

implemented Article 800-4, which mandates that “all equipment intended for connection to

the public telephone network be listed for that purpose” in order to ensure electrical safety.

A manufacturer can meet this requirement by listing their product with Underwriters

Laboratories under UL 60950 (based on IEC 60950, 3rd edition).

NEC requires all telecommunication wiring that enters a building to pass through a primary

protector, which is designed to limit AC transients in excess of 600 V rms. These transients

are due to the fact that telephone lines run in close proximity to AC power lines. Most

telecommunication equipment uses a secondary overvoltage protector such as the

SIDACtor device. The secondary devices typically limit transients in excess of 350 V rms.

Therefore, a potentially dangerous condition exists because of the voltage threshold

difference of the primary protector and the secondary protector. To minimize this danger,

compliance with UL 60950 overvoltage tests is required.

UL 60950 covers equipment with a rated voltage (primary power voltage) not exceeding

600 V and equipment designed to be installed in accordance with NEC NFPA 70. This

standard does not apply to air-conditioning equipment, fire detection equipment, power

supply systems, or transformers.

The effective date of UL 60950 allows new products submitted through April 1, 2003 to be

evaluated using the requirements of either UL 60950 or UL 1950, 3rd edition. After April 1,

2003, all new product submittals must be evaluated using only UL 60950.

Products certified by UL to requirements of UL 1459 prior to April 1, 2000 may continue to

be certified without further reinvestigation until April 1, 2005, provided no significant

changes or revisions are made to the products. Products certified by UL to requirements of

UL 1950 3rd edition prior to April 1, 2003 may continue to be certified without further

reinvestigation until April 1, 2005.

In order to have the UL Mark applied after April 1, 2005, all products, including those

previously certified by UL, must comply with UL 60950.

UL 69050 is intended to prevent injury or harm due to electrical shock, energy hazards, fire,

heat hazards, mechanical hazards, radiation hazards, and chemical hazards.

It defines three classes of equipment:

•

Class 1 — protection achieved by basic insulation

Class 2 — protection achieved by double or reinforced insulation

Class 3 — protection relying upon supply from SELV circuits (voltages up to 40 V peak

or 60 V dc)

UL 60950 also defines five categories of insulation:

•

Functional

Basic

Supplementary

Reinforced

Double

UL 60950 Terminology

The following definitions assist in understanding UL 60950:

SELV

(voltage less than hazardous levels of 42.4 V peak or 60 V dc)

TNV

Telecommunication Network Voltage (a secondary circuit)

O SELV but with exposure to surges

TNV1

O SELV but without exposure to surges

? SELV with exposure to surges

Creepage distance is the shortest distance between two conductors, measured along the

surface of the insulation. DC voltages shall be included in determining the working voltage

for creepage distances. (The peak value of any superimposed ripple or short disturbances,

such as cadenced ringing signals, shall be ignored.)

Clearance distance is the shortest distance between two conductive parts or between a

conductive part and the outer surface of the enclosure measured through air. DC voltages

and the peak value of any superimposed ripple shall be included in determining the working

voltage for clearance distances.

Creepage and clearance distances are also subject to the pollution degree of the

equipment:

•

Pollution degree 1 — components and assemblies that are sealed to prevent ingress of

dust and moisture

Pollution degree 2 — generally applicable to equipment covered by UL 60950

Pollution degree 3 — equipment is subject to conductive pollution or to dry non-

conductive pollution, which could become conductive due to expected condensation.

•

To ensure safe operating conditions of the equipment, UL 60950 focuses on the insulation

rating of the circuit(s) under consideration. Table 4.15 and Table 4.16 indicate the required

creepage and clearance distances depending on material group, pollution degree, working

voltage, and maximum transient voltage in the secondary circuit. For a typical

telecommunication application with a working voltage of 200 V, pollution degree 2, material

group IIIb, the creepage distance is 2 mm. The clearance distance is 2 mm for reinforced

insulation.

UL 60950 3rd Edition (formerly UL 1950, 3rd edition)

The application must meet the creepage and clearance distances and electric strength of

Section 5.3.2 of UL 60950 for functional insulation. The electric strength test (Table 5B of

UL 60950) lists 1 kV to 1.5 kV as the test voltages for functional and supplementary grade

of insulation and 2 kV to 3 kV for reinforced grade of insulation.

Separation requirements are tested (Section 6.2.2.1 of UL 60950) by applying an impulse

test and an electric strength test:

•

Impulse test allows for the SIDACtor device to turn on (either a 10x700 2.5 kV 62.5 A or

1 kV 37.5 A 10 times with 60-second rest period).

Electric strength test allows the SIDACtor device to be removed (60 Hz at rated voltage

for 60 seconds).

•

These are applied between Ground and all Tip and Rings connected together, and/or

between Ground and all conductors intended to be connected to other equipment

connected together.

Basic insulation is not required if all the following conditions are met:

•

SELV, TNV1 circuit is connected to the protective earth.

Installation procedures specify that protective earth terminal shall have a permanent

connection to earth.

•

Any TNV2 or TNV3 circuit with an external port connection intended to receive signals in

excess of SELV (60 V dc or 50 V peak) will have the maximum normal expected

operating voltage applied to it for up to 30 minutes without deterioration. (If no maximum

normal specification exists then 120 V 100 mA 60 Hz is applied.)

(In other words, if a permanent Ground connection is made, then creepage distances may

not be required.)

Any surge suppressor that bridges the insulation (connects to Ground) shall have a

minimum DC turn on voltage of 1.6 times the rated voltage UNLESS one of the following

occurs (Section 6.1.2.2 of UL 60950):

•

Equipment is permanently connected or uses an industrial plug and socket-outlet.

Equipment is installed by service personnel.

Equipment has provision for a permanently connected protective earth.

ANNEX C of UL 60950 covers transformers.

The secondary side is loaded for maximum heating effect. The maximum working voltage is

applied to the primary. The DC peak value of any superimposed ripple shall be included.

The permitted temperature limits for the windings depend on the classification:

•

Class A limit is 150 °C.

Class B limit is 175 °C.

Class E limit is 165 °C.

Class F limit is 190 °C.

Class H limit is 210 °C.

at a voltage of 120 V rms. Refer to Section 6.1.2 of UL 60950.

5. Fire Enclosure and Spacing — Fire enclosures minimize fire hazards by containing any emission of flame, molten metal,

flaming drops, or glowing particles that could be emitted by the equipment under fault conditions. Fire enclosure

construction is covered in Section 4.4.6 of UL 60950. Spacing applies to parts in the TNV circuits that might ignite under

overvoltage conditions. Spacing requirements mandate that parts be separated from internal materials of flammability

class V-2 or lower, by at least 25 mm of air or a barrier material of flammability class V-1 or better. Parts also should be

separated from openings in the top or sides of the enclosure by at least 25 mm of air or a material barrier.

6. Test Condition 2 is not required for equipment with 1.3 A limiting.

7. Test Conditions 3 and 4 are not required for connections limited to outside cable less than 1,000 m.

Overvoltage Test Procedures

Use the following criteria when applying the overvoltage tests presented in Table 4.17:

1. Test Set-up — Equipment is to be mounted as it is intended to be used. Tests may be

conducted on either the equipment as an assembly, individual subassemblies, or a

partial assembly containing those components which may be exposed to an overvoltage

condition.

2. Indicators — Before testing, two single pieces of cheesecloth are to be wrapped tightly

around the assembly, subassembly, or partial assembly. The cheesecloth acts as an

indicator for conditions that may result in fire.

3. Line Cords — Equipment with a removable telecommunications line cord is to be

connected to the test circuit with a line cord having 0.4 mm (26 AWG) or larger copper

wire conductors and not more than 1 ꢂ total resistance.

4. Functional Circuitry — UL mandates that functional circuitry must be used for each

overvoltage test conducted. This allows repair or replacement of damaged circuitry

before subsequent testing. Alternatively, separate samples may be used for each test.

5. Wiring Simulators — A wiring simulator is used to indicate whether the maximum I²t

imposed upon telecommunications wiring has been exceeded. For Tests 1 and 5, a

wiring simulator is to be used unless the equipment is specified for use with a suitable

secondary protector or a secondary protector simulator. The wiring simulator can consist

of one of the following:

a. 50mm length of 0.2 mm (32 AWG) bare or enameled solid copper wire (for test

condition 1)

b. Bussman Mfg. Co. Type MDL-2A fuse (for test condition 1)

c. 300 mm length of 0.4 mm (26 AWG) solid copper wire which connects to a

representative installation (includes wiring an connectors)

[This option is used when the manufacturer specifies the complete installation from

the network interface to the equipment.]

d. Current probe used with a 300 mm length of 0.5 mm (24 AWG) copper wire (for test

condition 1)

4 - 22

SIDACtor Data Book and Design Guide

®

UL 60950 3rd Edition (formerly UL 1950, 3rd edition)

Note: Test conditions 2, 3, and 4 do not require the use of a wiring simulator or a secondary

protector simulator. Any secondary protection simulators used in Tests 1 and 5

should be similar to the test fuse used in UL 497A, “Standard for Secondary

Protectors for Communications Circuits.”

Overvoltage Test Compliance

Equipment is deemed compliant if each of the following conditions are met during test:

•

Absence of ignition or charring of the cheesecloth indicator

(Charring is deemed to have occurred when the threads are reduced to char by a

glowing or flaming condition.)

Wiring simulator does not open during test condition 1 or 5

For test condition 1, presented in Table 4.17, the integral I²t measured with a current

probe is less than 100 A²s.

•

After completion of the overvoltage tests, equipment must comply with either the Dielectric

Voltage-withstand Test requirements with all components in place or the Leakage Current

Test requirements.

Special Considerations Regarding the SIDACtor Device and UL 60950

The epoxy used for SIDACtor devices is UL recognized and the encapsulated body passes

UL 94V-0 requirements for flammability.

The only specific requirements of UL 60950 that pertain to the SIDACtor device itself are

the impulse test and the mandate that components be UL recognized. All other UL 60950

requirements pertain to the equipment being evaluated.

UL 497

UL 497 Series of Safety Standards

The UL 497 series is a family of three safety standards that provides requirements for

protection devices used in low-voltage circuits.

•

UL 497 addresses requirements for primary protectors used in paired communications

circuits.

•

UL 497A covers secondary protectors for use in single or multiple pair-type

communications circuits.

•

UL 497B addresses protectors used in data communication and fire alarm circuits.

UL 497C addresses protectors for coaxial circuits.

The focus of UL 497 is to ensure that paired communication circuit protectors do not

become a fire or safety hazard. The requirements in UL 497 cover any protector that is

designed for paired communications circuits and is employed in accordance with Article 800

of the National Electric Code. The protectors covered in UL 497 include solid state primary

and station protectors. These circuit protectors are intended to protect equipment, wiring,

and service personnel against the effects of excessive voltage potential and currents in the

telephone lines caused by lightning, power cross, power induction, and rises in Ground

potential.

Performance Tests

Key performance tests which concern overvoltage protectors are detailed in the arrestor

test section. Specific requirements are:

•

Breakdown Voltage Measurement — Arrestors are to be tested in the protector blocks or

panels in which they are intended to be employed. Arrestors are required to break down

within ±25% of the manufacturer’s specified breakdown rating. In no case shall the

breakdown voltage exceed 750 V peak when subjected to the strike voltage test shown

in Figure 4.8. At no time during this test will the supply voltage be increased at a rate

greater than 2000 V/µs.

•

Impulse Spark-over Voltage Measurement — The arrestor must break down at less than

1000 V peak when subjected to a single impulse potential. Arrestors are to be tested in

each polarity with a rate of voltage rise of 100 V/µs, ±10%.

Abnormal Operation — Single pair fuseless arrestors must be able to simultaneously

carry 30 A rms at 480 V rms for 15 minutes without becoming a fire hazard. A fire hazard

is determined by mounting the arrestor on a vertical soft wood surface and covering the

unit with cheesecloth. Any charring or burning of the cheesecloth results in test failure.

During this test, although the arrestors may short, they must not have an impulse spark-

overvoltage or DC breakdown voltage greater than 1500 V peak.

•

Discharge Test — Protectors must comply with the strike voltage requirements after

being subjected to five successive discharges from a 2 µF capacitor charged to

1000 V dc. (Figure 4.9).

Repeated Discharge Test — The arrestor must continue to break down at or below its

maximum rated breakdown voltage after being subjected to 500 discharges from a

0.001 µF capacitor charged to a potential of 10,000 V dc. The interval between pulses is

five seconds. Arrestors are to be tested in each polarity, and it is acceptable for the

protector to short circuit following the discharge testing. (Figure 4.9)

Performance Tests

The following key performance tests relate to overvoltage protection of the secondary

protectors:

1. Impulse Voltage Measurement Test — Secondary protectors must break down within

±25% of the manufacturer’s breakdown rating when tested in each polarity with a rate of

voltage rise of 100 V/µs, ±10%. Note that the manufacturer may assign separate

breakdown voltage ratings for the Breakdown Voltage Measurement Test. This

requirement only applies to secondary protectors that connect between Tip and Ring of

the telephone loop.

2. Breakdown Voltage Measurement Test — Secondary protectors must break down within

±25% of the manufacturer’s breakdown rating when tested in each polarity with a rate of

voltage rise no greater than 2000 V/s. The secondary protector is to be mounted in

accordance with the manufacturer’s installation instructions and then subjected to the

test circuit shown in Figure 4.10. This requirement applies only to secondary protectors

connected between Tip and Ring or Tip/Ring and Ground of the telephone loop.

3. Overvoltage Test — Secondary protectors must limit current and extinguish or open the

telephone loop without loss of its overvoltage protector, indication of fire risk, or electric

shock. Upon completion of this test, samples must comply with the Dielectric Voltage-

withstand Test.

The overvoltage test is used to determine the effects on secondary protectors and is shown

in Table 4.18. Test connections are shown in Figure 4.11.

Test Compliance

Compliance with the overvoltage test is determined by meeting the following criteria:

•

Cheesecloth indicator may not be either charred or ignited

Wiring simulator (1.6 A Type MDQ fuse or 26 AWG line cord) may not be interrupted

Protector meets the applicable dielectric voltage withstand requirements after the

completion of the overvoltage tests

manufacturer’s specified breakdown range or within 10% of a nominal single breakdown

voltage rating. (Figure 4.12)

2. Endurance Conditioning — Protectors are subjected to 50 impulse cycles. Each cycle is

a 1000 V peak, 10 A, 10x1000 µs pulse. Pulses are applied in one polarity at 10-second

intervals and then repeated in the opposite polarity.

3. Variable Ambient Conditioning — Protectors must comply with the strike voltage

requirements after being subjected to an ambient temperature of 0 °C for four hours and

again after being subjected to an ambient temperature of 49 °C for an additional four

hours.

4. Discharge Test — Protectors must comply with strike voltage requirements after being

subjected to five successive discharges from a 2 µF capacitor charged to 1000 V dc.

(Figure 4.13)

5. Repeated Discharge Test — Protectors must not break down at a voltage higher than the

manufacturer’s maximum rated breakdown voltage nor lower than rated stand-off

Regulatory Compliant Solutions

When determining the most appropriate solution to meet the lightning and AC power fault

conditions for regulatory requirements, coordination is essential between the SIDACtor

device, fuse, and any series impedance that may be used.

Figure 4.14 through Figure 4.19 show templates in which this coordination is considered for

the most cost effective and reliable solutions available. For exact design criteria and

information regarding the applicable regulatory requirements, refer to the SIDACtor device

and fuse selection criteria in this Section 4, “Regulatory Requirements”, and in Section 5,

“Technical Notes”.

GR 1089 and ITU-T K.20 and K.21

Figure 4.14 and Figure 4.15 show line interface protection circuits to meet GR 1089 surge

immunity requirements without the additional use of series resistance. Use the “C” series

SIDACtor device and F1250T to meet GR 1089 surge immunity requirements. Use the

“A” series SIDACtor device and F0500T to meet ITU-T K.20 and K.21 basic surge immunity

requirements without the additional use of resistance.

The enhanced surge immunity requirements of ITU K.20 and K.21 require the use of “C”

rated SIDACtor devices if no series resistor is used.

Surge Waveforms for Various Standards

TIA-968 now replaces FCC Part 68, except for hearing aid compatibility (HAC), volume

control, and indoor cabling. This has become harmonized with Canadian requirements.

Various countries around the world have adopted this regulation.

GR 1089 is a standard generally supported by the US Regional Bell Operating Companies

(RBOC). It is updated by Telcordia Technology (formerly Bellcore). The RBOC typically

requires compliance with GR 1089 for any of their telecom purchases.

ITU is a specialized agency of the UN devoted to international harmonization. Most

European countries recognize the ITU standards.

CNET is the Centre National d’etudes de Telecommunications, a French organization.

VDE is the Verband Deutsher Elektrotechniker, a Federation of German electrical

engineers. VDE is very similar to the IEEE (Institute of Electrical and Electronics Engineers)

but is national in scope rather than global.

ANSI is the American National Standards Institute, which is a non-government organization.

The British equivalent to this is BSI.

IEC is the International Electrotechnical Commission, a result of Europe’s move toward a

single market structure and its drive to formalize and harmonize member countries’

requirements.

FTZ R12 is a German specification.

Table 4.19 and Table 4.20 show the recommended SIDACtor device surge rating for each

standard.

SIDACtor Data Book and Design Guide

Construction and Operation

SIDACtor devices are thyristor devices used to protect sensitive circuits from electrical

disturbances caused by lightning-induced surges, inductive-coupled spikes, and AC power

cross conditions. The unique structure and characteristics of the thyristor are used to create

an overvoltage protection device with precise and repeatable turn-on characteristics with

low voltage overshoot and high surge current capabilities.

Key Parameters

Key parameters for SIDACtor devices are V_DRM, I_DRM, V_S, I_H, and V_T, as shown in Figure 5.1.

V

_DRMis the repetitive peak off-state voltage rating of the device (also known as stand-off

voltage) and is the continuous peak combination of AC and DC voltage that may be applied

to the SIDACtor device in its off-state condition. I_DRMis the maximum value of leakage

current that results from the application of V_DRM. Switching voltage (V_S) is the maximum

voltage that subsequent components may be subjected to during a fast-rising (100 V/µs)

overvoltage condition. Holding current (I_H) is the minimum current required to maintain the

device in the on state. On-state voltage (V_T) is the maximum voltage across the device

during full conduction.

Figure 5.1 V-I Characteristics

Operation

The SIDACtor device operates much like a switch. In the off state, the device exhibits

leakage currents (I_DRM) less than 5 µA, making it invisible to the circuit it is protecting. As a

transient voltage exceeds the SIDACtor device’s V_DRM, the device begins to enter its

protective mode with characteristics similar to an avalanche diode. When supplied with

enough current (I_S), the SIDACtor device switches to an on state, shunting the surge from

the circuit it is protecting. While in the on state, the SIDACtor device is able to sink large

Construction and Operation

amounts of current because of the low voltage drop (V_T) across the device. Once the

current flowing through the device is either interrupted or falls below a minimum holding

current (I_H), the SIDACtor resets, returning to its off state. If the I_PPrating is exceeded, the

SIDACtor device typically becomes a permanent short circuit.

Physics

The SIDACtor device is a semiconductor device which is characterized as having four

layers of alternating conductivity: PNPN. (Figure 5.2) The four layers include an emitter

layer, an upper base layer, a mid-region layer, and a lower base layer. The emitter is

sometimes referred to as a cathode region, with the lower base layer being referred to as

an anode region.

As the voltage across the SIDACtor device increases and exceeds the device’s V_DRM, the

electric field across the center junction reaches a value sufficient to cause avalanche

multiplication. As avalanche multiplication occurs, the impedance of the device begins to

decrease, and current flow begins to increase until the SIDACtor device’s current gain

exceeds unity. Once unity is exceeded, the SIDACtor device switches from a high

impedance (measured at V_S) to a low impedance (measured at V_T) until the current flowing

through the device is reduced below its holding current (I_H).

SIDACtor Device Selection Criteria

When selecting a SIDACtor device, the following criteria should be used:

Off-state Voltage (V_DRM

)

The V

of the SIDACtor device must be greater than the maximum operating voltage of

DRM

the circuit that the SIDACtor device is protecting.

Example 1:

For a POTS (Plain Old Telephone Service) application, convert the maximum operating

Ring voltage (150 V rms) to a peak voltage, and add the maximum DC bias of the central

office battery:

150 V_RMSꢁ2 + 56.6 V_PK= 268.8 V_PK

ꢃꢀV_DRM> 268.8 V

Example 2:

For an ISDN application, add the maximum voltage of the DC power supply to the

maximum voltage of the transmission signal (for U.S. applications, the U-interface will not

have a DC voltage, but European ISDN applications may):

150 V_PK+ 3 V_PK= 153 V_PK

ꢃꢀV_DRM> 153 V

Switching Voltage (V_S)

The V of the SIDACtor device should be equal to or less than the instantaneous peak

S

voltage rating of the component it is protecting.

Example 1:

V_S? V_{Relay Breakdown}

Example 2:

V_S? SLIC V_PK

Peak Pulse Current (I_PP)

For circuits that do not require additional series resistance, the surge current rating (I_PP) of

the SIDACtor device should be greater than or equal to the surge currents associated with

the lightning immunity tests of the applicable regulatory requirement (I_PK):

I_PPO I_PK

For circuits that use additional series resistance, the surge current rating (I_PP) of the

SIDACtor device should be greater than or equal to the available surge currents associated

with the lightning immunity tests of the applicable regulatory requirement (I_{PK(available)}):

I_PPO I_{PK(available)}

SIDACtor Device Selection Criteria

The maximum available surge current is calculated by dividing the peak surge voltage (V_PK

by the total circuit resistance (R_TOTAL):

)

I_{PK(available)}= V_PK/R_TOTAL

For longitudinal surges (Tip-Ground, Ring-Ground), R_TOTALis calculated for both Tip and

Ring:

R

_SOURCE= V_PK/I_PK

R_TOTAL= R_TIP+ R_SOURCE

R_TOTAL= R_RING+ R_SOURCE

For metallic surges (Tip-Ring):

R_SOURCE= V_PK/I_PK

R_TOTAL= R_TIP+ R_RING+ R_SOURCE

Example 1:

A modem manufacturer must pass the Type A surge requirement of TIA-968 (formerly

known as FCC Part 68) without any series resistance.

I

_PK= 100 A, 10x560 µs

I_PPO 100 A, 10x560 µs

Therefore, either a “B” rated or “C” rated SIDACtor device would be selected.

Example 2:

A line card manufacturer must pass the surge requirements of GR 1089 with 30 ꢂ on Tip

and 30 ꢂ on Ring.

I_{PK (available)}= V_PK/R_TOTAL= 1000 V/40 ꢂ

ꢃ I_PPO 25 A

Holding Current (I_H)

Because TIA-968 4.4.1.7.3 specifies that registered terminal equipment not exceed

140 mA dc per conductor under short-circuit conditions, the holding current of the SIDACtor

device is set at 150 mA.

For specific design criteria, the holding current (I_H) of the SIDACtor device must be greater

than the DC current that can be supplied during an operational and short circuit condition.

Off-State Capacitance (C_O)

Assuming that the critical point of insertion loss is 70% of the original signal value, the

SIDACtor device can be used in most applications with transmission speeds up to 30 MHz.

For transmission speeds greater than 30 MHz, the new MC series is highly recommended.

Fuse Selection Criteria

A fuse can be relied upon to operate safely at its rated current, at or below its rated voltage.

This voltage rating is covered by the National Electric Code (NEC) regulations and is a

requirement of UL as protection against fire risk. The standard voltage ratings used by fuse

manufacturers for most small dimension fuses are 32 V, 63 V, 125 V, 250 V, and 600 V.

Fuses are not sensitive to changes in voltage; however, they are sensitive to changes in

current. The fuse will maintain “steady-state” operation from zero volts to the maximum

voltage rating. It is not until the fuse element melts and internal arcing occurs, that circuit

voltage and available power become an issue. The interrupt rating of the fuse addresses

this issue. Specifically, the voltage rating determines the ability of the fuse to suppress

internal arcing that occurs after the fuse link melts.

For telecommunication applications, a voltage rating of 250 V is chosen because of the

possibility of power line crosses. A three-phase voltage line will have voltage values up to

220 V. It is desirable for the voltage rating of the fuse to exceed this possible power cross

event.

UL 60950 has a power cross test condition that requires a fuse to have an interrupt rating of

40 A at 600 V. GR 1089 contains a power cross test condition that requires a fuse to have

an interrupt rating of 60 A at 600 V. A 125 V-rated part will not meet this requirement.

A 250 V part with special design consideration, such as Teccor’s F1250T TeleLink

fuse, does meet this requirement.

Because fuses are rated in terms of continuous voltage and current-carrying capacity, it is

often difficult to translate this information in terms of peak pulse current ratings. To simplify

this process, Table 5.1 shows the surge rating correlation to fuse rating.

SIDACtor Data Book and Design Guide

Overvoltage Protection Comparison

The four most commonly used technologies for overvoltage protection are:

•

SIDACtor devices

Gas Discharge Tubes (GDTs)

Metal Oxide Varistors (MOVs)

TVS diodes

All four technologies are connected in parallel with the circuit being protected, and all exhibit

a high off-state impedance when biased with a voltage less than their respective blocking

voltages.

SIDACtor devices

A SIDACtor device is a PNPN device that can be thought of as a TVS diode with a gate.

Upon exceeding its peak off-state voltage (V_DRM), a SIDACtor device will clamp a transient

voltage to within the device’s switching voltage (V_S) rating. Then, once the current flowing

through the SIDACtor device exceeds its switching current, the device will crowbar and

simulate a short-circuit condition. When the current flowing through the SIDACtor device is

less than the device’s holding current (I_H), the SIDACtor device will reset and return to its

high off-state impedance.

Advantages

Advantages of the SIDACtor device include its fast response time (Figure 5.3), stable

electrical characteristics, long term reliability, and low capacitance. Also, because the

SIDACtor device is a crowbar device, it cannot be damaged by voltage and it has extremely

high surge current ratings.

Restrictions

Because the SIDACtor device is a crowbar device, it cannot be used directly across the

AC line; it must be placed behind a load. Failing to do so will result in exceeding the

SIDACtor device’s surge current rating, which may cause the device to enter a permanent

short-circuit condition.

Applications

Although found in other applications, SIDACtor devices are primarily used as the principle

overvoltage protector in telecommunications and data communications circuits. For

applications outside this realm, follow the design criteria in "SIDACtor Device Selection

Criteria" on page 5-5.

Gas Discharge Tubes

Gas tubes are either glass or ceramic packages filled with an inert gas and capped on each

end with an electrode. When a transient voltage exceeds the DC breakdown rating of the

device, the voltage differential causes the electrodes of the gas tube to fire, resulting in an

arc, which in turn ionizes the gas within the tube and provides a low impedance path for the

transient to follow. Once the transient drops below the DC holdover voltage and current, the

gas tube returns to its off state.

Advantages

Gas tubes have high surge current and low capacitance ratings. Current ratings can be as

high as 500 A for 200 impulses, and capacitance ratings can be as low as 1 pF with a zero-

volt bias.

Restrictions

Gas tubes have a limited shelf life and their performance degrades with usage. Out of the

four devices discussed, gas tubes exhibit the slowest response time and highest peak

voltage measurement. (Figure 5.3)

Applications

Because gas tubes are large and require a substantial amount of time to reach full

conduction, they are rarely used as board-level components. Consequently, gas tubes are

not normally used in telecommunications applications other than station protection

modules.

Metal Oxide Varistors

Metal Oxide Varistors (MOVs) are two-leaded, through-hole components typically shaped in

the form of discs. Manufactured from sintered oxides and schematically equivalent to two

back-to-back PN junctions, MOVs shunt transients by decreasing their resistance as

voltage is applied.

Advantages

Since MOVs surge capabilities are determined by their physical dimensions, high surge

current ratings are available. Also, because MOVs are clamping devices, they can be used

as transient protectors in secondary AC power line applications.

Restrictions

Like gas tubes, MOVs have slow response times resulting in peak clamping voltages which

can be greater than twice the device’s voltage rating. (Figure 5.3) MOVs also have long-

term reliability and performance issues due to their tendency to fatigue, high capacitance,

and limited packaging options.

Applications

Although MOVs are restricted from use in many telecom applications (other than disposable

equipment), they are useful in AC applications where a clamping device is required and

tight voltage tolerances are not.

Overvoltage Protection Comparison

TVS Diodes

Transient Voltage Suppressor (TVS) diodes are clamping voltage suppressors that are

constructed with back-to-back PN junctions. During conduction, TVS diodes create a low

impedance path by varying their resistance as voltage is applied across their terminals.

Once the voltage is removed, the diode will turn off and return to its high off-state

impedance.

Advantages

Because TVS diodes are solid state devices, they do not fatigue nor do their electrical

parameters change as long as they are operated within their specified limits. TVS diodes

effectively clamp fast-rising transients and are well suited for low-voltage applications that

do not require large amounts of energy to be shunted.

Restrictions

Because TVS diodes are clamping devices, they have two inherent weaknesses. First, TVS

diodes are both voltage- and current-limited, so careful consideration should be given to

using these in applications that require large amounts of energy to be shunted. Secondly,

as the amount of current flowing through the device increases, so does its maximum

clamping voltage.

Applications

Due to their low power ratings, TVS diodes are not used as primary interface protectors

across Tip and Ring; they are used as secondary protectors that are embedded within a

circuit.

Overcurrent Protection

In addition to protecting against overvoltage conditions, equipment should also be protected

from overcurrent conditions using either PTCs, fuses, power/line feed resistors, or

flameproof resistors. In all instances the overcurrent protector is a series element placed in

front of the overvoltage protector on either Tip or Ring for metallic (closed loop)

applications and on both Tip and Ring for longitudinal (grounded) applications.

PTCs

PTCs are positive temperature coefficient thermistors used to limit current. During a fault

condition, heat is generated at a rate equal to I²R. When this heat becomes sufficient, the

PTC increases its resistance asymptotically until the device simulates an open circuit,

limiting the current flow to the rest of the circuit. As the fault condition drops below the

PTC’s holding current, the device begins to reset, approximating its original off-state value

of impedance.

Advantages

Because PTCs are resettable devices, they work well in a variety of industrial applications

where electrical components cannot withstand multiple, low-current faults.

Restrictions

Although PTCs are well suited for the industrial environment and in many telecom

applications, they exhibit some limitations that have prevented them from being endorsed

by the entire telecommunications industry. Limitations include low surge current ratings,

unstable resistance, and poor packaging options.

Applications

PTCs are used in a variety of applications. In addition to protecting telecommunications

equipment, PTCs are also used to prevent damage to rechargeable battery packs, to

interrupt the current flow during a motor lock condition, and to limit the sneak currents that

may cause damage to a five-pin module.

Fuses

Due to their stability, fuses are one of the most popular solutions for meeting AC power

cross requirements for telecommunications equipment. Similar to PTCs, fuses function by

reacting to the heat generated due to excessive current flow. Once the fuses I²t rating is

exceeded, the center conductor opens.

Advantages

Fuses are available in both surface mount and through-hole packages and are able to

withstand the applicable regulatory requirements without the use of any additional series

impedance. Chosen correctly, fuses only interrupt a circuit when extreme fault conditions

exist and, when coordinated properly with an overvoltage protector, offer a very competitive

and effective solution for transient immunity needs.

Overcurrent Protection

Advantages include:

•

Elimination of series line resistance enabling longer loop lengths

Precise longitudinal balance allowing better transmission quality

Robust surge performance which eliminates costly down time due to nuisance blows

Greater surge ratings than resettable devices, ensuring regulatory compliance

Non-degenerative performance

Available in surface mount packaging which uses less Printed Circuit Board (PCB) real

estate, eliminates mixed technologies, and reduces manufacturing costs

Weaknesses

Because a fuse does not reset, consideration should be given to its use in applications

where multiple fault occurrences are likely. For example, AC strip protectors and ground

fault interrupting circuits (GFIC) are applications in which an alternative solution might be

more prudent.

Applications

Telecommunications equipment best suited for a fuse is equipment that requires surface

mount technology, accurate longitudinal balance, and regulatory compliance without the

use of additional series line impedance.

Selection Criteria

For circuits that do not require additional series resistance, the surge current rating (I_PP) of

the TeleLink SM fuse should be greater than or equal to the surge currents associated with

the lightning immunity tests of the applicable regulatory requirement (I_PK).

I_PPOꢀI_PK

For circuits that use additional series resistance, the surge current rating (I_PP) of the

TeleLink SM fuse should be greater than or equal to the available surge currents associated

with the lightning immunity tests of the applicable regulatory requirement (I_{PK (available)}).

I_PPOꢀI_{PK (available)}

The maximum available surge current is calculated by dividing the peak surge voltage (V_PK

by the total circuit resistance (R_TOTAL).

Power/Line Feed Resistors

Typically manufactured with a ceramic case or substrate, power and line feed resistors

have the ability to sink a great deal of energy and are capable of withstanding both lightning

and power cross conditions.

Advantages

Power and line feed resistors are available with very tight resistive tolerances, making them

appropriate for applications that require precise longitudinal balance.

Restrictions

Because power and line feed resistors are typically very large and are not available in a

surface mount configuration, these devices are less than desirable from a manufacturing

point of view. Also, because a thermal link is typically not provided, power and line feed

resistors may require either a fuse or a PTC to act as the fusing element during a power

cross condition.

Applications

Power and line feed resistors are typically found on line cards that use overvoltage

protectors that cannot withstand the surge currents associated with applicable regulatory

requirements.

Flameproof Resistors

For cost-sensitive designs, small (1/8 W - 1/4 W), flameproof metal film resistors are often

used in lieu of PTCs, fuses, and power or line feed resistors. During a transient condition,

flameproof resistors open when the resultant energy is great enough to melt the metal used

in the device.

Advantages

Flameproof resistors are inexpensive and plentiful.

PCB Layout

Because the interface portion of a Printed Circuit Board (PCB) is subjected to high voltages

and surge currents, consideration should be given to the trace widths, trace separation, and

grounding.

Trace Widths

Based on the Institute for Interconnecting and Packaging Electronic Currents, IPC D 275

specifies the trace widths required for various current-carrying capacities. This is very

important for grounding conditions to ensure the integrity of the trace during a surge event.

The required width is dependent on the amount of copper used for the trace and the

acceptable temperature rise which can be tolerated. Teccor recommends a 0.025 inch trace

width with 1 ounce copper. (For example, a 38-AWG wire is approximately equal to 8 mils to

10 mils. Therefore, the minimum trace width should be greater than 10 mils.)

Conductor Cross-Section Area (sq mils)

Figure 5.4 Current versus Area

The minimum width and thickness of conductors on a PCB is determined primarily by the

current-carrying capacity required. This current-carrying capacity is limited by the allowable

temperature rise of the etched copper conductor. An adjacent ground or power layer can

significantly reduce this temperature rise. A single ground plane can generally raise the

allowed current by 50%. An easy approximation can be generated by starting with the

information in Figure 5.4 to calculate the conductor cross-sectional area required. Once this

Trace Separation

Tip and Ring traces are subjected to various transient and overvoltage conditions. To

prevent arcing between traces, minimum trace separation should be maintained. UL 60950

will provide additional information regarding creepage and clearance requirements, which

are dependent on the Comparative Tracking Index (CTI) rating of the PCB, working voltage,

and the expected operating environment. See "UL 60950 3rd Edition (formerly UL 1950, 3rd

edition)" on page 4-16 of this data book.

A good rule of thumb for outside layers is to maintain a minimum of 18 mils for 1kV isolation.

Route the Tip and Ring traces towards the edge of the PCB away from areas containing

static sensitive devices.

Grounding

Although often overlooked, grounding is a very important design consideration when laying

out a protection interface circuit. To optimize its effectiveness, several things should be

considered in sequence:

1. Provide a large copper plane with a grid pattern for the Ground reference point.

2. Decide if a single-point or a multi-point grounding scheme is to be used. A single-point

(also called centralized) grounding scheme is used for circuit dimensions smaller than

one-tenth of a wavelength (ꢄ = 300,000/frequency) and a multi-point (distributed)

grounding scheme is used for circuit trace lengths greater than one-fourth of a

wavelength.

PCB Layout

3. Because traces exhibit a certain level of inductance, keep the length of the ground trace

on the PCB as short as possible in order to minimize its voltage contribution during a

transient condition. In order to determine the actual voltage contributed to trace

inductance, use the following equations:

V = L (di/dt)

L = 0.0051 ꢅꢀ[log_e2 ꢅ/(t+w) +½ - log_eG] in µH

where ꢅꢀ= length of trace

G = function of thickness and width as provided in Table 5.3

t = trace thickness

w = trace width

For example, assume circuit A is protected by a P3100SC with a V_Sequal to 300 V and a

ground trace one inch in length and a self-inductance equal to 2.4 µH/inch. Assume

circuit B has the identical characteristics as Circuit A, except the ground trace is five inches

in length instead of one inch in length. If both circuits are surged with a 100 A, 10x1000 µs

wave-form, the results would be as shown in Table 5.2:

Table 5.2 Overshoot Caused by Trace Inductance

Total protection level

V_L= L (di/dt)

V_L= 2.4 µH (100 A/10 µs) = 24 V

Other practices to ensure sound grounding techniques are:

1. Cross signal grounds and earth grounds perpendicularly in order to minimize the field

effects of “noisy” power supplies.

2. Make sure that the ground fingers on any edge connector extend farther out than any

power or signal leads in order to guarantee that the ground connection invariably is

connected first.

SIDACtor Soldering Recommendations

When placing surface mount components, a good solder bond is critical because:

•

The solder provides a thermal path in which heat is dissipated from the packaged silicon

to the rest of the board.

•

A good bond is less subject to thermal fatiguing and results in improved component

reliability.

Reflow Soldering

The preferred technique for mounting the DO-214AA package is to reflow-solder the device

onto a PCB-printed circuit board, as shown in Figure 5.6.

1. Screen print solder paste

(or flux)

2. Place component

(allow flux to dry)

3. Reflow solder

Figure 5.6 Reflow Soldering Procedure

For reliable connections, the PCB should first be screen printed with a solder paste or

fluxed with an easily removable, reliable solution, such as Alpha 5003 diluted with benzyl

alcohol. If using a flux, the PCB should be allowed to dry to touch at room temperature (or in

a 70 °C oven) prior to placing the components on the solder pads.

Relying on the adhesive nature of the solder paste or flux to prevent the devices from

moving prior to reflow, components should be placed with either a vacuum pencil or

automated pick and place machine.

With the components in place, the PCB should be heated to a point where the solder on the

pads begins to flow. This is typically done on a conveyor belt which first transports the PCB

through a pre-heating zone. The pre-heating zone is necessary in order to reduce thermal

shock and prevent damage to the devices being soldered, and should be limited to a

maximum temperature of 165 °C for 10 seconds.

After pre-heating, the PCB goes to a vapor zone, as shown in Figure 5.7. The vapor zone is

obtained by heating an inactive fluid to its boiling point while using a vapor lock to regulate

the chamber temperature. This temperature is typically 215 °C, but for temperatures in

excess of 215 °C, care should be taken so that the maximum temperature of the leads does

During reflow, the surface tension of the liquid solder draws the leads of the device towards

the center of the soldering area, correcting any misalignment that may have occurred

during placement and allowing the device to set flush on the pad. If the footprints of the pad

are not concentrically aligned, the same effect can result in undesirable shifts as well.

Therefore, it is important to use a standard contact pattern which leaves sufficient room for

self-positioning.

After the solder cools, connections should be visually inspected and remnants of the flux

removed using a vapor degreaser with an azeotrope solvent or equivalent.

Wave Soldering

Another common method for soldering components to a PCB is wave soldering. After

fluxing the PCB, an adhesive is applied to the respective footprints so that components can

be glued in place. Once the adhesive has cured, the board is pre-heated and then placed in

contact with a molten wave of solder which has a temperature between 240 °C and 260 °C

and permanently affixes the component to the PCB. (Figure 5.8 and Figure 5.10)

Although a popular method of soldering, wave soldering does have drawbacks:

•

A double pass is often required to remove excess solder.

Solder bridging and shadows begin to occur as board density increases.

Wave soldering uses the sharpest thermal gradient.

TeleLink Fuse Soldering

For wave soldering a TeleLink fuse, the following temperature and time are recommended:

•

Reservoir temperature of 260 °C (500 °F)

Time in reservoir — three seconds maximum

For infrared, the following temperature and time are recommended:

•

Temperature of 240 °C (464 °F)

Time — 30 seconds maximum

Hand soldering is not recommended for this fuse because excessive heat can affect the

fuse performance. Hand soldering should be used only for rework and low volume samples.

Note the following recommendations for hand soldering:

•

Maximum tip temperature of 240 °C (464 °F)

Minimize the soldering time at temperature to achieve the solder joint. Measure the fuse

resistance before and after soldering. Any fuse that shifts more than ±3% should be

replaced. An increase in resistance above this amount increases the possibility of a

surge failure, and a decrease in resistance may cause low overloads to exceed the

maximum opening times.

•

Inspect the solder joint to ensure an adequate solder fillet has been produced without

any cracks or visible defects.

Telecommunications Protection

Because early telecommunications equipment was constructed with components such as

mechanical relays, coils, and vacuum tubes, it was somewhat immune to lightning and

power cross conditions. But as cross bar and step-by-step switches have given way to more

modern equipment such as digital loop carriers, repeater amplifiers, and multiplexers, an

emphasis has been put on protecting this equipment against system transients caused by

lightning and power cross conditions.

Lightning

During an electrical storm, transient voltages are induced onto the telecommunications

system by lightning currents which enter the conductive shield of suspended cable or

through buried cables via ground currents.

As this occurs, the current traveling through the conductive shield of the cable produces an

equal voltage on both the Tip and Ring conductors at the terminating ends. Known as a

longitudinal voltage surge, the peak value and wave-form associated with this condition is

dependent upon the distance the transient travels down the cable and the materials with

which the cable is constructed.

Although lightning-induced surges are always longitudinal in nature, imbalances resulting

from terminating equipment and asymmetric operation of primary protectors can result in

metallic transients as well. A Tip-to-Ring surge is normally seen in terminating equipment

and is the primary reason most regulatory agencies require telecom equipment to have

both longitudinal and metallic surge protection.

Power Cross

Another system transient that is a common occurrence for telecommunications cables is

exposure to the AC power system. The common use of poles, trenches, and ground wires

results in varying levels of exposure which can be categorized as direct power cross, power

induction, and ground potential rise.

Direct power cross occurs when a power line makes direct contact to telecommunications

cables. Direct contact is commonly caused by falling trees, winter icing, severe

thunderstorms, and vehicle accidents. Direct power cross can result in large currents being

present on the line.

Power induction is common where power cables and telecommunications cables are run in

close proximity to one another. Electromagnetic coupling between the cables results in

system transients being induced onto the telecommunications cables, which in turn can

cause excessive heating and fires in terminal equipment located at the cable ends.

Ground potential rise is a result of large fault currents flowing to Ground. Due to the varying

soil resistivity and multiple grounding points, system potential differences may result.

Lightning

Lightning is one of nature’s most common and dangerous phenomena. At any one time,

approximately 2,000 thunderstorms are in progress around the globe, with lightning striking

the earth over 100 times per second. According to IEEE C.62, during a single year in the

United States lightning strikes an average of 52 times per square mile, resulting in 100

deaths, 250 injuries, and over 100 million dollars in damage to equipment property.

The Lightning Phenomenon

Lightning is caused by the complex interaction of rain, ice, up drafts, and down drafts that

occur during a typical thunderstorm. The movement of rain droplets and ice within the cloud

results in a large build up of electrical charges at the top and bottom of the thunder cloud.

Normally, positive charges are concentrated at the top of the thunderhead while negative

charges accumulate near the bottom. Lightning itself does not occur until the potential

difference between two charges is great enough to overcome the insulating resistance of air

between them.

Formation of Lightning

Cloud-to-ground lightning begins forming as the level of negative charge contained in the

lower cloud levels begins to increase and attract the positive charge located at Ground.

When the formation of negative charge reaches its peak level, a surge of electrons called a

stepped leader begins to head towards the earth. Moving in 50-meter increments, the

stepped leader initiates the electrical path (channel) for the lightning strike. As the stepped

leader moves closer to the ground, the mutual attraction between positive and negative

charges results in a positive stream of electrons being pulled up from the ground to the

stepped leader. The positively charged stream is known as a streamer. When the streamer

and stepped leader make contact, it completes the electrical circuit between the cloud and

ground. At that instant, an explosive flow of electrons travels to ground at half the speed of

light and completes the formation of the lightning bolt.

Lightning Bolt

The initial flash of a lightning bolt results when the stepped leader and the streamer make

connection resulting in the conduction of current to Ground. Subsequent strokes (3-4) occur

as large amounts of negative charge move farther up the stepped leader. Known as return

strokes, these subsequent bolts heat the air to temperatures in excess of 50,000 °F and

cause the flickering flash that is associated with lightning. The total duration of most

lightning bolts lasts between 500 ms and one second.

During a lightning strike, the associated voltages range from 20,000 V to 1,000,000 V while

currents average around 35,000 A. However, maximum currents associated with lightning

have been measured as high as 300,000 A.
