1 Introduction
3URGXꢁWꢀ'HVꢁULSWLRQ
SIDACtors are solid state crowbar devices designed to protect telecom equipment
during hazardous transient conditions. Capitalizing on the latest in thyristor
advancements, Teccor designs their SIDACtors with a patented ion implant
technology. This technology ensures effective protection within nanoseconds, 500A
surge current ratings, and simple solutions for regulatory requirements such as
Bellcore 1089, FCC Part 68, ITU-T K. 20, ITU-T K. 21and UL1459 & 1950.
Operation
In the standby mode, SIDACtors 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 (VS), SIDACtors will
crowbar and simulate a short circuit condition until the current flowing through the
device is either interrupted or drops below the SIDACtor’s holding current (IH). Once
this occurs, SIDACtors will reset and return to their high off-state impedance.

Product Description
SIDACtor® Data Book
Advantages
The advantages of using a SIDACtor over other surge suppression devices is that the
SIDACtor offers absolute surge protection regardless of the surge current available
and the rate of applied voltage (dV/dt). Unlike other devices, the SIDACtor:
• Can not be damaged by voltage
• Eliminates hysteresis and heat dissipation typically found with a clamping
device
• Eliminates voltage overshoot caused by fast rising transients
• Is non-degenerative
• Will not fatigue
• Has negligible capacitance making it ideal for high speed transmission
equipment
Applications
When protecting telecommunication circuits, the SIDACtor is connected across Tip
and Ring for metallic protection and across Tip, Ring, and ground for longitudinal
protection. SIDACtors are typically placed behind some type of current limiting device
such as a slow blow fuse. Common applications are:
• Central office line cards
• T-1/E-1, ISDN, and xDSL transmission equipment
• Customer Premises Equipment (CPE) such as phones, modems, and caller ID
adjunct boxes
• PBX’s, KSU’s and other switches
• Primary protection including main distribution frames, 5-pin modules, building
entrance equipment and station protection modules
• Data lines and security systems
• CATV line amplifiers and power inserters
• Sprinkler systems
For more information regarding specific applications, design requirements, or surge
suppression, please contact Teccor Electronics directly at (972) 580-7777 or through
our local area representative. Access Teccor’s web site at http://www.teccor.com or

Overview
CPE is defined as any telephone terminal equipment which resides at the customers
site and is connected to the public switched telephone network (PSTN). Telephones,
modems, caller ID adjunct boxes, PBX’s and answering machines are all considered
CPE.
Protection Requirements
CPE should be protected against over-voltages that can exceed 800V and surge
currents up to 100A. In Figures 3-1 through 3-5, the SIDACtor was chosen because
the associated peak pulse current (IPP) is great enough to withstand the lightning
immunity test of FCC Part 68 without the additional use of series line impedance.
2
2
Likewise, the fuse in Figures 3-1 through 3-5 was chosen because the amps time (I t)
rating is large enough to withstand the lightning immunity tests of FCC Part 68, but
small enough to pass UL power cross conditions.
Applicable Regulatory Requirements
• FCC Part 68
• UL 1459
• UL 1950
All CPE that is intended for connection to the PSTN must be registered in compliance
with FCC Part 68. 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
Figures 3-1 through 3-5 are 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 (VDRM) is greater than the potential of a
Type B ringer superimposed on a POTS (plain old telephone service) battery.
150VRMS √2 + 56.6Vpk = 268.8Vpk
It should be noted that the circuits shown in Figures 3-1 through 3-5 provide an
operational solution for FCC Part 68, however FCC Part 68 allows CPE designs to
pass non-operationally as well.
2
For a non-operational solution, the IPP rating of the SIDACtor and the I t rating of the
fuse should be coordinated such that both will withstand the Type B surge, but during
the Type A surge, the fuse will open (Table 5-1, Fuse Selection Criteria).
Note: For alternative line interface protection circuits, please refer to Regulatory Requirements
and Regulatory Compliant Solutions.

Digital Transmission Equipment
'LJLWDOꢀ7UDQVPLVVLRQꢀ(TXLSPHQW
Overview
Digital transmission equipment encompasses a broad range of transmission protocols
such as T1/E1, xDSL, and ISDN. Digital transmission equipment is located at the
central office, customer premises, and remote locations.
Protection Requirements
Digital transmission equipment should be protected against over-voltages that can
exceed 2500V and surge currents up to 500A. In Figures 3-7 through 3-17, the
SIDACtor was chosen because the associated peak pulse current (IPP) is great
enough to withstand the lightning immunity tests of GR 1089 without the additional use
of series line impedance. Likewise, the fuse in Figures 3-7 through 3-17 was chosen
because the amps2time (I2t) rating is large enough to withstand the lightning immunity
tests of GR 1089, but small enough to pass GR 1089 current limiting protector test and
power cross conditions.
Applicable Regulatory Requirements
• FCC Part 68
• GR 1089-CORE
• ITU-T K.20
• UL 1459
• UL 1950
Most transmission equipment sold in the US must adhere to GR 1089. For Europe and
other regions, ITU-T K.20 is typically the recognized standard.

ADSL/CDSL Circuit Protection
Asymmetric Digital Subscriber Lines (ADSL) and Consumer Digital Subscriber Lines
(CDSL) employ an asymmetic digital line technology (Figure 3-7). This technology
employs a transmission rate up to 6.144 Mbps from the Central Office Terminal (COT)
to the Remote Terminal (RT) and a 640 kbps transmission rate from the RT to the COT
at distances up to 12,000 feet. Currently ANSI T1.413 specifies a maximum ring
voltage of 103VRMS and a boosted battery of 60VDC, however this is subject to
change.
Protection Circuitry
In Figure 3-8, longitudinal protection was not used at either the ATU-C interface or the
ATU-R interface due to the absence of earth ground connections. In both instances,
metallic protection is accomplished using the P3500SC SIDACtor and F1250T
TeleLink. For ATU’s not isolated from earth ground, please reference the HDSL
protection topology.
Component Selection
The P3500SC SIDACtor and F1250T TeleLink were chosen to protect the ATU’s
because both components meet GR 1089 surge immunity requirements without the
use of additional series resistance. Furthermore, although the P3100 series SIDACtor
may be used to meet current ANSI specifications, Teccor recommends the P3500
series to ensure compliance with a 150VRMS ringing signal superimposed on a
105VDC boosted battery.

HDSL Circuit Protection
High Bit Digital Subscriber Lines (HDSL) employ a digital line technology that utilizes a
1.544 Mbps (T-1 equivalent) transmission rate for distances up to 12,000 feet,
eliminating the need for repeaters. The signaling levels are a maximum of +/- 2.5V
while loop powering is typically under 190V.
Protection Circuitry
Longitudinal protection is required at both of the HTU-C and HTU-R interfaces
because of the ground connection used with loop powering. In Figure 3-10, this is
accomplished using two P2300SC SIDACtor’s for over voltage protection and two
F1250T TeleLink fuses (one on TIP, one on RING) for over current protection. For the
transceiver side of the coupling transformer, additional over voltage protection is
shown using the P0080SA SIDACtor.
Component Selection
The P2300SC SIDACtor and the F1250 TeleLink were chosen because both
components meet GR 1089 surge immunity requirements without the use of additional
series resistance. The P2300SC voltage rating was selected to ensure loop powering
up to 180V. For loop powering greater than 180V, the P2600SC should be considered.
The P0080SA SIDACtor was chosen to eliminate any sneak voltages that may appear
below the voltage rating of the P2300SC.

ISDN Circuit Protection
Integrated Services Digital Network (ISDN) circuits require protection at the NT1 U-
interface and at the Terminating Equipment (TE) and/or Terminating Adapter (TA) S/T
interface. Signal levels at the U interface are typically +/-2.5V, but with sealing currents
and Maintenance Loop Test (MLT) procedures, voltages approaching 150VRMS can
occur.
Protection Circuitry
In Figure 3-12, longitudinal protection was not used at either the U or the TA/TE
interface due to the absence of an earth to ground connection. At the U interface,
metallic protection is accomplished using the P2600SC SIDACtor and F1250T
TeleLink while the TA/TE interface uses the P0640SC SIDACtor and F1250T TeleLink.
For interfaces not isolated from earth ground, please reference the HDSL protection
topology.
Component Selection
The “SC” SIDACtors and F1250T TeleLink were chosen because these components
meet GR 1089 surge immunity requirements without the use of additional series
resistance. The P2600SC voltage rating was selected to ensure coordination with
MLT voltages that can approach 150VRMS. The voltage rating of the P0640SC 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 10V up to 145V with a typical maximum current of 75mA.
Protection Circuitry
In Figure 3-14, longitudinal protection is required at the Central Office Terminal (COT)
interface because of the ground connection used with loop powering. This is
accomplished using two P1800SC SIDACtor’s for over voltage protection and two
F1250T TeleLink fuses (one on TIP, one on RING) for over current protection. For the
U-interface side of the coupling transformer, additional over voltage protection is
shown using the P0080SA SIDACtor.
For the Customer Premises (CP) and the Remote Terminal (RT) interfaces where an earth
ground connection is not utilized, only metallic protection is required. Figure 3-15 shows
metallic protection being satisfied using a single P3100SC across TIP and RING and a
single F1250T on either Tip or Ring.
Component Selection
The “SC” SIDACtor and F1250T TeleLink were chosen because both components
meet GR 1089 surge immunity requirements without the use of additional series
resistance. The voltage rating of the P1800SC was selected to ensure coordination
with loop powering up to 150V. The voltage rating of the P3100SC was selected to
ensure coordination with POTS ringing and battery voltages.

T-1/E-1 Circuit Protection
T-1/E-1 networks offer data rates up to 1.544 Mbps (2.058 for E-1) on a four wire
system. Signal levels on the TX pair are typically between 2.4V and 3.6V while the RX
pair could go as high as 12V. Loop powering is typically +/-130V at 60mA, although
some systems can go as high as 150V.
Protection Circuitry
In Figure 3-17, longitudinal protection is required at the Central Office Terminal (COT)
interface because of the ground connection used with loop powering. This is
accomplished using two P1800SC SIDACtor’s for over voltage protection and two
F1250T TeleLink fuses (one on TIP, one on RING) for over current protection. For the
transceiver side of the coupling transformer, additional over voltage protection is
shown using the P0300SA SIDACtor. For the regenerator where an earth ground
connection is not utilized, only metallic protection is required. Metallic protection is
satisfied using a single P0640SC SIDACtor across TIP and RING and a single F1250T
TeleLink on either Tip or Ring.

Because 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 designed to ensure reliable operation and
regulatory compliance.
Protection Requirements
When designing over voltage protection for analog line cards, it is often necessary to
provide both on-hook (relay) and off-hook (SLIC) protection. Figure 3-18 shows this
being accomplished in two stages.

On-Hook (Relay) Protection
On-hook protection is accomplished by choosing a SIDACtor that meets the following
criteria to ensure proper coordination between the ring voltage and the maximum
voltage rating of the relay to be protected.
VDRM>VBATT+VRING
VS≤VRelay Breakdown
This criterion is typically accomplished using two P2600S_ (where _ denotes the surge
current rating) SIDACtors connected from TIP to GND and RING to GND. However
those who choose to use relays such as Lucent’s LCAS (Line Card Access Switch)
should consider the P1200S_ from TIP to GND and the P2000S_ from RING to GND.
Off-Hook (SLIC) Protection
Off-hook protection is accomplished by choosing a SIDACtor that meets the following
criteria to ensure proper coordination between the supply voltage (VREF) and the
maximum voltage rating of the SLIC to be protected.
VDRM>VREF
VS≤VSLIC Breakdown
This criterion can be accomplished a variety of different ways. For applications that
use an external ring generator and a fixed battery voltage, two P0641S_ (or P0721S_
depending on the value of VREF) SIDACtors are used; one TIP to GND, one RING to
GND. For applications that use a ring generating SLIC such as AMD’s Am79R79, the
P11xx0C_ can be used.
IPP Selection
To ensure the proper surge current rating of the SIDACtor is selected, the IPP of the
SIDACtor must be greater than or equal to the maximum available surge current
(IPK(available)) of the applicable regulatory requirements. The maximum available surge
current is calculated by dividing the peak surge voltage supplied by the voltage
generator (VPK) by the total circuit resistance (RTOTAL). The total circuit resistance is
determined by adding the source resistance (RS) of the surge generator to the series
resistance that is in front of the SIDACtor on both TIP and RING (RTIP and RRING).

PP≥IPK(available)
IPK(available)=VPK/RTOTAL

Reference Diagrams
Figure 3-19 uses Teccor’s “C” rated SIDACtors and the F1250T TeleLink fuse to meet
the surge immunity requirements of Bellcore 1089. On-hook protection is
accomplished using Teccor’s P1200SC and P200SC which were specifically designed
to protect Lucent Microelectronics Line Card Access Switch (LCAS). Off-hook
protection is accomplished using two P0641SC’s. Note the absence of any additional
series resistance. This is because the “C” series SIDACtor and F1250T TeleLink were
designed to withstand GR 1089 without the aid of additional components such as line
feed resistors and PTC’s.
Figure 3-20 uses the P2600SA and P0721SA for over voltage protection and the
F0500T for over current protection in addition to 20Ω of series resistance on both TIP
and RING. The series resistance is required to limit the transient surge currents to
within the surge current rating of the “A” series SIDACtors and the F0500T TeleLink
fuse.
Figure 3-21 uses Teccor’s Battrax to protect AMD’s Am79R79 from over-voltages and
the F1250T to protect against sustained power cross conditions. The Battrax was
designed specifically to protect SLIC’s that can not withstand potential differences
greater than VREF ±10V.
Figure 3-22 shows how to protect a SLIC by utilizing 20Ω series resistors on both TIP
and RING in addition to Teccor’s Battrax (B1100CC) and a diode bridge (General
Semiconductor p/n EDF1BS). However, the overshoot caused by the diode bridge
must be considered. The series resistance (a minimum of 20Ω on TIP and 20Ω on
RING) limits the 100A simultaneous surge current from TIP to GND and RING to GND
(200A total) to within the surge current rating of the SIDACtor and Battrax. The diode
bridge shunts all positive voltages to GND and the B1100CC shunts all negative
voltages greater than |-VREF –1.2V| to GND.
Some applications may require the use of 50Ω line feed resistors. In this instance,
Figure 3-23 shows how to replace multiple SLIC protectors using one B1160CC and
two EDF1BS diode bridges. The overshoot caused by the diode bridge must be
considered. The only caution in such an approach with regards to the Battrax is that it
is imperative that the sum of the loop currents does not exceed the Battrax’s holding
current. In Figure 3-23, the loop current would have to be limited to 80mA. For
applications that would require 4 twisted pair to be protected with one Battrax, the
B1200CC should be used and the loop current would have to be limited to 50mA.

Figures 3-25 & 3-26 show how the P1900ME SIDACtor is used to protect line
amplifiers and power supplies versus using Teccor’s patented circuit that requires two

Station Protection Reference Circuit
Figure 3-28 shows a P1400MD SIDACtor used in a CATV station protection
application. Note that a compensation inductor may be required to meet insertion and
reflection loss requirements for CATV networks. If so, the inductor should be designed
to saturate quickly and withstand surges of up to 200V and 1000A. An inductor with a
core permeability of approximately 900 and wound with 24 gauge wire to an
inductance of 20 to 30 µH is an example of a suitable starting point, but the actual
value is design dependent and must be verified through laboratory testing.

Primary Protection
3ULPDU\ꢀ3URWHꢁWLRQ
Overview
Primary telecommunications protectors are required to 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) and is done so to
protect end users from the hazards associated with lightning and power cross
conditions.
Provided by the local exchange carrier, primary protection can be segregated into
three distinct categories:
1. Station protection - typically associated with a single twisted pair.
2. Building entrance protection - typically associated with multiple (25 or more)
twisted pair.
3. 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 companies lines from the customer’s.
Building entrance protection is accomplished by installing a multi-line distribution panel
that has integrated over-voltage protection. These panels are normally located where
multiple twisted pairs enter a building.
Central and remote office protection is accomplished using a 5-pin protection module
which is plugged into a main distribution frame (MDF). Like station and building
entrance protection, the MDF is located where exposed cables enter the switching
office.
Protection Requirements
Station protectors should be able to withstand over-voltages that exceed 5000V and
surge currents up to 250A. Building entrance and 5-pin module protectors should be
able to withstand over-voltages that exceed 2500V and surge currents of up to 100A.
The SIDACtors shown in Figures 3-29 & 3-30 meet these requirements.

Primary Protection Reference Circuit
Figures 3-29 & 3-30 show different configurations used in primary protection. It should
be noted that the peak off-state voltage (VDRM) of any device intended to be used 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
6HꢁRQGDU\ꢀ3URWHꢁWLRQ
Secondary Protectors
Secondary protectors are adjunct devices (they can be either stand alone units or
integrated into strip protectors and UPS’) used to enhance the protection level of
customer premise equipment (CPE). Due to the inadequate level of protection being
designed into CPE, secondary protectors are often required to help prevent premature
failure of equipment that is exposed to environmental hazards (Figure 3-31).
Protection Requirements
Secondary protectors should be able to withstand over-voltages that can exceed 800V
and surge currents of up to 100A. In Figure 3-32, the SIDACtor was chosen because
the associated peak pulse current (IPP) is great enough to withstand the lightning
immunity tests of FCC Part 68 without the additional use of series line impedance.
Likewise, the fuse in Figure 3-32 was chosen because the amps2time (I2t) rating is
large enough to withstand the lightning immunity tests of FCC Part 68, but small
enough to pass UL power cross conditions.
Applicable Regulatory Requirements
• UL 497A
Secondary Protection Reference Circuit
Figure 3-32 is an example of an interface design for a secondary protector. The
P3203AB SIDACtor is used because the peak off-state voltage (VDRM) is greater than
the potential of a Type B ringer signal superimposed on the POTS (plain old telephone
service) battery.
150VRMS√2 + 56.6Vpk = 268.8Vpk
Coordination between the station protector and the secondary protector occurs due to
the line impedance between the two devices (Figure 3-31). 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 VS rating of the SIDACtor.

Triac Protection
7ULDꢁꢀ3URWHꢁWLRQ
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, etc.
Thyristor Reference Circuit
Figures 3-33 & 3-34 show two different methods of protecting a triac. In Figure 3-33, a
SIDACtor is connected from MT2 to the gate of the triac. When the voltage applied to
the triac exceeds the SIDACtor’s VDRM, the SIDACtor turns on, producing a gate
current which turns the triac on.
The circuit in Figure 3-34 places a SIDACtor across MT2 and MT1 of the triac. In this
instance the SIDACtor protects the triac by turning on and shunting the transient
before it exceeds the VDRM rating of the triac.
Regardless of the method chosen, when using a SIDACtor to protect a thyristor, the
following design considerations must be followed:
• VDRM of the SIDACtor < VDRM of Triac
• SIDACtor must be placed behind the load
• SIDACtor VDRM > 120% VPK(power supply)

Regulatory
Requirements
Due to the enormous cost of interrupted service and failed
network equipment, service providers have adopted
various specifications to help regulate the reliability and
performance of the telecommunications product 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, FCC Part 68, and UL1459/

*5ꢀꢄꢇꢋꢆꢂ&RUHꢀ
Overview
In the United States, the telecommunication network is primarily operated by the
Regional Bell Operating Companies (RBOC's) which follow the standards set by
Bellcore or a derivative thereof. GR 1089-Core (often referred to as Bellcore 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, and addresses the
criteria for protection from lightning and AC power cross disturbances.
Because twisted pair can be likened to metallic conductors exposed to lightning and
AC power faults, GR 1089 has documented the standards they feel should be met by
manufacturers of public switched telephone network (PSTN) equipment to ensure safe
and reliable operation.
The criteria used to set these standards is 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 (typically found
in the form of gas discharge tubes or carbon blocks) which is meant to limit transient
voltages to 1000VPK for surge conditions and 600VRMS for power cross conditions.
In conjunction with primary voltage protectors, operating companies may also
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, will be 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 350mA.
Requirements
Equipment required to meet GR 1089 must be designed to pass both First and Second
Level Lightning Surge and AC Power Fault Tests, a Current Limiter Test, and a Short
Circuit Test. A minimum of three units will be tested for each of the operating states
that the equipment under test (EUT) may be expected to function; idle, transmit,
receive, on-hook, off-hook, talking, dialing, ringing, and testing. Test connections are
shown in Table 4-1 and connection appearances are shown in Figure 4-1.

Passing Criteria
Passing criteria for the First Level Lightning Surge Test and the First Level AC Power
Fault Test is that the EUT will not be damaged and it will operate as intended after the
stress is removed. Passing criteria for the Second Level Lightning Surge Test and
Second Level 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 (i.e., it can not cause the wiring simulator 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 which is wrapped around the EUT.
Compliance with testing is determined by the absence of ignition, charring, and the
ejection of molten material or fragments.
Lightning Fault Immunity Test
Metallic Voltage - is defined as the potential difference between Tip and Ring. Metallic
voltages occur when there is an imperfect balance on the twisted pair. This imbalance
typically arises due to unmatched components, but can also occur when longitudinal
surges are converted to metallic surges due to asymmetrical operation of over-voltage
protectors.
Longitudinal Voltage - is defined by Bellcore as half of the sum of the potential
difference seen between the Tip conductor and earth ground and the Ring conductor
and earth ground. During transient activity, damaging voltages are propagated over
the phone lines raising the potential difference of each line with respect to earth
ground. It is this potential difference that is often attributed to failed network equipment
and is simulated in Tests 1, 2, 3, and 5 in Table 4-2.
Test 4 in Table 4-2 simulates transients that are coupled to the network equipment via
ground conductors. These transients occur when nearby lightning strikes produce
large surge currents which generate excessive voltage due to the resistive path of the
protector and power grounds.
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 removed. This is referred to as passing
“operationally”. The conditions for the First Level criteria are shown in Table 4-2. The
applicants have the option to submit their equipment to meet surges 1, 2, 4 and 5 or
surges 3, 4, and 5.

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
Because power companies and operating companies often share telephone poles,
trenches, and the like, 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 companies network equipment may see as much as 600VRMS
for 5 seconds, by which time the power companies power system should clear itself. If
direct contact occurs with the secondary power line, voltages will be limited to
277VRMS, but 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.

Teccor Electronics
(972)580-7777
SIDACtor® Data Book
GR 1089-Core
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 the phone lines via electro-magnetic coupling. In this instance voltages
should be limited to 1000VPK and 600VRMS by the primary protectors, while the
current will be limited by the current carrying capacity of the 24 gauge wire.
First Level AC Power Fault Criteria
Test conditions for the First Level AC Power Fault Test are shown in Table 4-4. The

the EUT is intended for customer premises equipment or non-customer premises
equipment. In both instances, although the EUT is not required to pass operationally, it
may not become a fire, fragmentation, or electrical safety hazard.

Second Level AC Power Fault for Customer Premises Equipment
For customer premises equipment, the EUT is tested to the conditions shown in Table
4-6 and connected to a circuit equivalent to Figure 4-2. During this test, the wiring
simulator can not open. For equipment that uses premises type of wiring, the wiring
simulator is a 1.6A Type MDQ fuse from Bussman. For equipment that is connected
via cable, the wiring simulator is a piece of 26 gauge copper wire.

The purpose of the Current Limiting Protector Test (Table 4-7) 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 Figure 4-2 with a 1.6A 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 has not been met
and external current limiting protectors must be specified for use with that equipment in

comply with the short circuit test, the EUT must function normally after the short-circuit
condition has been applied and a fire hazard may not be present.
Intra-Building Lightning and AC Power Fault Test
Not all equipment is intended to be off premise equipment nor is all equipment
intended to interface with the telephone outside plant. For such equipment, the EUT
need only meet the Intra-Building Lightning Surge Test found in Table 4-8 and the
Intra-Building AC Power Fault Test found in Table 4-9.

Overview
Although the ITU does not have the authority to legislate that organizations follow their
recommendations, their standards are recognized in many places throughout Europe
and the Far East.
ITU-T, the Telecommunication Standardization Sector of the International
Telecommunication Union, has developed fundamental testing methods that have
been established to cover various environmental conditions to help predict the
survivability of network and customer based switching equipment. The conditions
covered are surges due to lightning strikes on or near twisted pair and or plant
equipment (this does not include a direct strike), short term induction of AC voltage
from adjacent power lines or railway systems, and direct contact between
telecommunication lines and power lines (this is often referred to as AC power cross).
The two applicable ITU-T standards for most telecommunications equipment to be
connected to the network are ITU-T K.20 which is primarily for switching equipment
powered by the central office, and ITU-T K.21 which focuses on customer premise
equipment. However, for complex subscriber equipment, test administrators may
choose either K.20 or K.21, depending on which they feel is most appropriate.
Note:
Both standards are meant to address equipment reliability versus equipment safety, so
for specific concerns regarding equipment safety, national standards should be
researched and followed for each country where the equipment is intended to be used.
ITU-T K.20
Covers telephone exchanges and switching centers. Equipment submitted under K.20
must meet one of two levels. The lower level is intended for equipment that is used in
an unexposed environment where over-voltages and over-currents are expected to be
small and external protectors omitted (similar to the intra-building scenario found in
Bellcore 1089). The higher level is intended to cover more exposed environments
where external line protectors are used. Guidelines for determining which environment
the equipment under test (EUT) falls under can be found in ITU-T K.11, but it should be
noted that the final authority rests with the test administrator. That being the case, and
since equipment satisfying the requirements of the exposed criteria can also meet the
requirements satisfying the non-exposed requirements, only the exposed level
requirements are addressed in this document.
ITU-T K.21
Addresses desk-borne equipment that may or may not be used in an exposed
environment. It is assumed that external line protectors are employed for equipment
used in exposed areas and not used for unexposed environments. With this in mind,
K.21 is conducted with and without external line protectors.

SIDACtor® Data Book
External Protectors
For equipment being tested to the exposed level, it is standard practice for external
line protectors (typically gas tubes) to be used in order to handle the large surge
currents generated during K.20 and K.21 qualification. Realizing that these protectors
can affect the characteristics of the EUT, it is important that the protectors used be
agreed upon by the principal parties involved (the equipment supplier and testing
administrator). Once agreed upon, the protectors should be used when primary
protection is specified, and allowance should be given for a new set of protectors after
the completion of each test sequence.
Note:
An alternative to using external protectors is for the test administrator to simulate the
conditions expected (as if the external protectors were used) by modifying the surges
found in K.20 and K.21.
Equipment Boundaries
Because of the numerous types of equipment, during K.20 and K.21 testing ITU-T
looks at each EUT as a “black box” with three terminals (A, B, and E). The applicant is
expected to define the boundaries of this “black box”, and in doing so, should be aware
that any protective device within these boundaries is considered an unchangeable part
of that piece of equipment.
Permitted Malfunction or Damage
During K.20 and K.21 qualification, ITU-T recognizes two levels of malfunction or
damage to the EUT:
• Level A states that equipment withstands the test without damage or disturbance
and operates properly after the test. If specifically permitted, the administration
may accept the opening of the fuse.
• Level B states that a fire hazard does not occur in the equipment as a result of the
test, and that any permanent damage or malfunction is confined to a small number
of external line interface circuits (as defined by the test administrator).
The acceptable level of malfunction for each test is specified under Acceptance
Criteria.

FCC PART 68
)&&ꢀ3$57ꢀꢈꢋ
Overview
FCC Part 68 applies to all terminal equipment that is connected to the public network
and is unique in the fact that it is mandated by U.S. law.
The purpose of FCC Part 68 is to provide a set of uniform standards that will protect
the telephone network from any damage or interference caused by the connection of
terminal equipment. The FCC 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 of which must be met before and after the
environmental tests are applied.
Over-Voltage Test
FCC compliant equipment must undergo an over-voltage 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 FCC's environmental simulation, and although there is
a provision which allows the EUT to reach an open circuit failure mode during the Type
A tests, failures must:
1. Arise from an intentional design which will cause the phone to be either
disconnected from the public network or repaired rapidly.
2. Be designed such 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, etc.). The Type A surge is an 800V, 100A peak surge while the Type B surge is
a 1000V, 25A peak surge (Table 4-16).
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 1500V, 200A
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 1500V and
37.5A are applied to Tip with respect to ground and Ring with respect to ground
concurrently (Table 4-16).

Notes:
1. For Type A surges, the EUT may be pass either “operationally” or “non-operationally”.
2. For Type B surges, the EUT must pass operationally.
3. The Peak Current for the Type A longitudinal surge is the total available curent from the surge
generator.
4. The Peak Current for the Type B longitudinal surge is the current supplied to each conductor.
Special Note:
FCC Type B surge requirements only guarantee 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 FCC Part 68 which is affected by transient protection is on
hook impedance. On hook impedance is analogous to the leakage current between Tip
and Ring, and Tip, Ring and ground conductors during various on hook conditions.
Criteria for on hook impedance is outlined below and is listed as part of the Ringer
Equivalent Number (REN) by the FCC. The REN is the largest of the unitless quotients
not greater than 5, and the rating is specified as the actual quotient followed by the
letter of the ringer classification, e.g., 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 100V, the
DC resistance measured must be greater than 5MΩ. For all DC voltages between 100
and 200V, the DC resistance must be greater than 30kΩ. The REN values are then
determined by dividing 25MΩ by the minimum measured resistance up to 100V and by
dividing 150kΩ by the minimum measured resistance between 100 and 200V.
On-hook impedance is also measured during the application of a simulated ringing
signal. This consists of a 40 through 150VRMS ringer signal at frequencies ranging
from 15.3 to 68.0Hz superimposed on a 56.5VDC for a class “B” ringer. During this
test, the total DC current may not exceed 3mA. In addition, the minimum DC
resistance measured between Tip and Ring must be greater than 1600Ω while the DC
resistance measured between the Tip and Ring conductors and ground must be
greater than 100kΩ. The REN values for the simulated ringing test are determined by
dividing the maximum DC current flowing between Tip and Ring by 0.6mA, and by
dividing 8000Ω by the minimum impedance value measured.

UL 1459 2nd Edition
8/ꢀꢄꢅꢍꢆꢀꢃQGꢀ(GLWLRQ
Overview
After the 1984 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” to help ensure electrical
safety. One way a manufacturer can meet this requirement is to “list” their product with
Underwriters Laboratories under UL 1459 (also see UL1950).
UL 1459
Because telephone lines run in close proximity to AC power lines, the NEC requires
that all telecommunication wiring that enters a building pass through a primary
protector which is designed to limit AC transients in excess of 600VRMS. But because
most telecommunication equipment incorporates a secondary over-voltage protector
that is designed to shunt transient voltages in excess of 250VRMS, a potentially
dangerous condition arises because of the voltage gap that exists between these two
protectors.
Consider the following: a transient condition exists and the secondary over-voltage
protector triggers, but the primary protector does not, i.e. a 440VRMS power cross. The
secondary protector will shunt the transient voltage for as long as the transient
condition exists or until the current path is interrupted. Now assume a worse case
scenario; that the resultant current path is not interrupted and the power cross is
indefinite. The net result will be the ignition of the premises wiring, the equipment, or
both.
To help minimize this likelihood, UL requires that all registered equipment comply with
the over-voltage tests listed in UL 1459, section 50A.
Over-Voltage Tests
The over-voltage tests found in section 50A of UL 1459 use two separate test circuits
to simulate a 600VRMS crossover between an AC power line and a
telecommunications line. The circuit used in Figure 4-9 simulates a metallic power
cross by applying a voltage potential between Tip and Ring. The circuit used in Figure
4-10 simulates a longitudinal power cross by applying a voltage potential between Tip
and Ring with respect to earth ground.
Table 4-17 outlines the applicable over-voltage tests which simulate long and short
term induction as well as direct power contact. The most common approach to pass
these tests is to add a series fuse element on Tip and Ring for applications that
connect to earth ground, or add a series fuse element on either Tip or Ring for
applications that do not connect to earth ground.
Note:
Because telephone circuits typically draw 40-100mA of current during normal
operation, fuses should be selected to be large enough to prevent nuisance tripping
yet small enough that they won’t allow the wiring simulator to open during test. Fuse
values between 250mA and 1.25A meet this requirement.

Failure Modes
Equipment under test can fail the over-voltage tests listed in Table 4-17 one of two
ways. The first is to allow the wire simulator (a 1.6A Type MDQ fuse by Bussman) in
Figures 4-9 and 4-10 to open which indicates that enough current was drawn during
test to actually cause ignition of premises wiring.
The second is to allow a piece of white, unbleached cheesecloth which is wrapped
around the EUT to either ignite or show signs of charring, which indicates that the EUT
may become a serious fire hazard under power cross conditions.
Notes Concerning the SIDACtor and UL 1459
• SIDACtors are recognized under UL 497B, file no. E133083 (Standard for
Secondary protectors for data communications and fire alarm circuits).
• SIDACtors use epoxy that is UL recognized and the encapsulated body passes UL
94V-0 requirements for flammability.
• The only specific requirements of UL 1459 that pertain to the SIDACtor itself is the
mandate that components be UL listed. All other UL 1459 requirements pertain to
the equipment being evaluated.

Overview
In an attempt to harmonize North American safety standards with Europe’s IEC 950,
Underwriters Laboratories and the Canadian Standards Association have adopted a
bi-national standard, UL 1950 in the U.S and CSA C22.2 No. 950-95 in Canada, to
replace UL1459 and CSA C22.2.
UL 1950 (CSA C22.2 No. 950-95) is applicable to “information technology equipment”
with a rated voltage not exceeding 600VRMS, that is intended to be powered by either a
battery or electrical mains, and is designed to be installed in accordance with the
Canadian Electric Code, the National Electric Code, and NFPA 70. Effective dates are
as follows:
1. July 28, 1995-April 1, 2000: New product submittals will be evaluated against
the requirements of UL 1950 (CSA C22.2 No. 950-95) unless use of another
existing national standard is requested in writing by the manufacturer.
2. From April 1st, 2000: Products previously approved in accordance with existing
national standards, i.e., UL 1459 and CSA 22.2, will continue to be considered
approved until April, 1 2005.
3. As of April 5th, 2005: All products, whether new or previously approved, must
comply with UL 1950 (CSA C22.2 No. 950-95).
UL 1950
Like UL 1459, UL 1950 is intended to help ensure the electrical safety of equipment
that is connected to the public switched telecommunications network (PSTN). And
although the over-voltage requirements are somewhat similar, UL1950 permits design
engineers a much greater degree of flexibility through the use of design exceptions
found in the Over-Voltage Flowchart (Figure 4-11).
Over-Voltage Flowchart
The Over-Voltage Flowchart contains specific guidelines that determine which over-
voltage requirements are applicable to specific designs. Applicable information that
pertains to the Over-Voltage Flowchart is:
1. Current Limiting - Equipment that has a fire enclosure along with methods for
limiting current to an I2t rating of 100A2s or 1.3A steady state, is not subject to
over-voltage testing.
2. 26 AWG Line Cord - This refers to a 26 American Wire Gauge (AWG)
telecommunications line cord that is either supplied with the equipment or is
described in the safety instructions.
3. Clause 6.3.3 - The telephone line must be adequately isolated from earth for the
operating mode being considered and at a voltage of 120VRMS. Refer to
section 6.3.3 of UL1950.
4. Fire Enclosure - 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 1950.

UL 1950 3RD Edition/CSA C22.2 No. 950-95
5. Spacing - Applies to parts in the TNV circuits that might ignite under over-
voltage conditions. Spacing requirements mandate that parts be separated
from internal materials of flammability class V-2 or lower, by at least 25mm of
air or a barrier material of flammability class V-1 or better. Parts should also be
separated from openings in the top or sides of the enclosure by at least 25mm
of air or a material barrier.
6. Over-Voltage Tests - Equipment may be subject to the tests in Table 4-18 which
are designed to simulate contact with primary power, short term induction as a
result of a primary power fault to a multi-earth neutral, a long duration power
fault to ground, and direct contact between the power mains and a
telecommunications cable.

Over-Voltage Test Procedures
The following criteria is used when applying the over-voltage tests found in Table 4-18:
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 over-voltage 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.

UL 1950 3RD Edition/CSA C22.2 No. 950-95
SIDACtor® Data Book
3. Line Cords - Equipment that has a removable telecommunications line cord is to
be connected to the test circuit with a line cord having 0.4mm (26 AWG) or
larger copper wire conductors and not more than 1Ω total resistance.
4. Functional Circuitry - UL mandates that functional circuitry must be used for
each over-voltage test conducted. This allows damaged circuitry to be repaired
or replaced 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 &
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. A 50mm length of .2mm (32 AWG) bare or enameled solid copper wire
(for Test condition 1).
b. A Bussman Mfg. Co. Type MDL-2A fuse (for Test condition 1).
c. A 300mm length of .4mm (no. 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 300mm length of .5mm (24 AWG) copper wire
(for Test condition 1).
Note:
Test conditions 2, 3, & 4 do not require the use of a wiring simulator or a secondary
protector simulator. Any secondary protection simulators used in Tests 1 & 5 should be
similar to the test fuse used in UL 497A, Standard for Secondary Protectors for
Communications Circuits.
Over-Voltage Test Compliance
Equipment is deemed compliant if both of the following conditions are met during test:
1. An absence of ignition or charring of the cheesecloth indicator (charring is
deemed to have occurred when the threads have been reduced to char by a
glowing or flaming condition).
2. The wiring simulator (Figures 4-12 & 4-13) does not open during the appropriate
2
test, or for test condition 1 (Table 4-18), the integral I t measured with a current
2
probe is less than 100A s.
After completion of the Over-Voltage Tests, equipment must comply with either the
Dielectric Voltage-Withstand Test requirements or Leakage Current Test requirements
listed in sections 6.3 and 6.4 of UL 1950.
Special Considerations Regarding the SIDACtor and UL 1950.
• SIDACtors are recognized under UL 497B
• SIDACtor epoxy used is UL recognized and the encapsulated body passes
UL 94V-0 requirements for flammability.
• The only specific requirements of UL 1950 that pertains to the SIDACtor itself is the
mandate that components be UL listed. All other UL 1950 requirements pertain to
the equipment being evaluated.

UL 497 Series of Safety Standards
The UL 497 series is a family of three safety standards which provide requirements for
protection devices used in low voltage circuits.
• UL 497 issues 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
Overview
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.
Construction and Performance
UL 497 is divided into two sections which cover construction and performance.
Table 4-19 lists the content of each section.
Performance Tests
Key performance tests which concern over-voltage 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 breakdown within ± 25% of the manufacturers specified breakdown rating. In no
case shall the breakdown voltage exceed 750VPK when subjected to the strike
voltage test shown in Figure 4-14. At no time during this test will the supply voltage
be increased at a rate greater than 2000Vµs.
• Impulse Spark-Over Voltage Measurement - The arrestor must breakdown at less
than 1000VPK when subjected to a single impulse potential. Arrestors are to be
tested in each polarity with a rate of voltage rise of 100V/µs, ± 10%.
• Abnormal Operation - Single pair fuse-less arrestors must be able to simultaneously
carry 30ARMS at 480VRMS 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-over voltage or dc breakdown voltage greater than
1500VPK
.
• Discharge Test - Protectors must comply with the strike voltage requirements after
being subjected to five successive discharges from a 2µF capacitor charged to
1000VDC (Figure 4-15).
• Repeated Discharge Test - The arrestor must continue to breakdown at or below its
Teccor Electronics

UL 497
SIDACtor® Data Book
maximum rated breakdown voltage after being subjected to 500 discharges from a
.001µF capacitor charged to a potential of 10,000VDC. The interval between pulses
is 5 seconds. Arrestors are to be tested in each polarity and it is acceptable for the
protector to short circuit following the discharge testing (Figure 4-15).

Overview
UL 497A addresses secondary protectors for use in single or multiple pair-type
communication circuits that are intended to be installed in accordance with Article 800
of the National Electric Code and have an operating voltage of less than 150VRMS with
respect to ground. The purpose of UL 497A is to help reduce the risk of fire, electric
shock, or injury resulting from the deployment and use of these protectors.
Construction and Performance
UL 497A is divided into three sections covering construction, risk of injury, and
performance requirements. Table 4-20 lists the contents of each section.

Performance Tests
Key performance tests which concern over-voltage protection of the secondary
protectors are:
1. Impulse Voltage Measurement Test - Secondary protectors must breakdown
within ± 25% of the manufacturers breakdown rating when tested in each
polarity with a rate of voltage rise of 100V/µs, ± 10%. It should be noted 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 breakdown
within ± 25% of the manufacturers breakdown rating when tested in each
polarity with a rate of voltage rise no greater than 2000V/s. The secondary
protector is to be mounted in accordance with the manufacturer’s installation
instructions and then subjected to the test circuit in Figure 4-16. This
requirement only applies to secondary protectors connected between Tip and
Ring or Tip/Ring and ground of the telephone loop.
3. Over-Voltage Test - Secondary protectors must limit current and extinguish or
open the telephone loop without loss of its over-voltage protector, indication of
fire risk, or electric shock. Upon completion of this test, samples must comply
with the dielectric voltage-withstand test.
The Over-Voltage Test is used to determine the effects on secondary protectors and is
shown in Table 4-21. Test connections are shown in Figure 4-17.
Test Compliance
Compliance with the Over-Voltage Test is determined by meeting the following criteria:
• The cheesecloth indicator may not be either charred or ignited.
• The wiring simulator (1.6A Type MDQ fuse or 26 AWG line cord) may not be
interrupted.
• The protector will meet the applicable dielectric voltage withstand requirements
after the completion of the over-voltage tests.

Performance Requirements Specific to the SIDACtor
1. Strike Voltage Breakdown Test - Protectors are required to breakdown within the
manufacturers specified breakdown range or within 10% of a nominal single
breakdown voltage rating (Figure 4-18).
2. Endurance Conditioning - Protectors are subjected to 50 impulse cycles. Each
cycle is a 1000VPK, 10A, 10x1000µs 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 4
hours and again after being subjected to an ambient temperature of 49°C for an
additional 4 hours.
4. Discharge Test - Protectors must comply with strike voltage requirements after
being subjected to five successive discharges from a 2µF capacitor charged to
1000VDC (Figure 4-19).
Teccor Electronics
(972) 580-7777

UL 497B
SIDACtor® Data Book
5. Repeated Discharge Test - Protectors must not break down at a voltage higher
than the manufacturers maximum rated breakdown voltage nor lower than
rated stand-off voltage after being subjected to 500 discharges from a .001µF
capacitor charged to 10000VDC. The discharges are applied in 5 second
intervals between one side of the protector and ground. Upon completion of the
discharge tests, protectors are once again required to meet the strike voltage
requirement (Figure 4-19).

Overview
When determining the most appropriate solution to meet the lightning and AC power
fault conditions for regulatory requirements, coordination between the SIDACtor, fuse,
and any series impedance that may be used is essential.
The following figures have taken this coordination into consideration and are offered
as templates for the most cost effective and reliable solutions available. For exact
design criteria and information regarding the applicable regulatory requirements,
please refer to the SIDACtor and fuse selection criteria in Chapter 5 and the previous
sections in Regulatory Requirements.

FCC Part 68 and UL 1459/UL 1950
Because equipment that is tested to FCC Part 68 specifications is also generally
tested to UL specifications, it is easiest to look at a solution that meets both FCC and
UL requirements simultaneously.
FCC Part 68 Operational Solution and UL 1459/UL 1950
Figures 4-22 and 4-23 are line interface protection circuits that meet both UL 1459 and
UL1950 power cross requirements and pass FCC Part 68 Type A and Type B lightning
immunity tests operationally.
FCC Part 68 Non-Operational Solution and UL 1459/UL 1950
Although Figures 4-22 and 4-23 provide an operational solution for FCC Part 68, FCC
Part 68 allows telecommunications equipment to pass Type A surges non-
operationally as well. For non-operational FCC Part 68 solutions, the IPP rating of the
SIDACtor and the I2t rating of the fuse should be coordinated such that both will
withstand the FCC Part 68 Type B surge, but during the Type A surge, the fuse will
open.
Figures 4-24 and 4-25 are line interface protection circuits that meet UL power cross
requirements and pass FCC Part 68 lightning immunity tests non-operationally.

Overview
SIDACtors are thyristor devices used to protect sensitive circuits from electrical
disturbances caused by lightning and AC power cross conditions. The unique structure
and characteristics of the thyristor are used to create an over-voltage protection device
with precise and repeatable turn-on characteristics with low voltage overshoot and
high surge current capabilities.
Key Parameters
Key parameters for SIDACtors are VDRM, IDRM, VS, IH, and VT. VDRM is the repetitive
peak off-state voltage rating of the device (also know as stand-off voltage) and is the
continuous peak combination of AC and DC voltage that may be applied to the
SIDACtor in its off-state condition. IDRM is the maximum value of leakage current that
results from the application of VDRM. Switching voltage (VS) is the maximum voltage
that subsequent components may be subjected to during a fast rising (100V/µs) over-
voltage condition. Holding current (IH) is the minimum current required to maintain the
device in the on-state. And on-state voltage (VT) is the maximum voltage across the
device during full conduction.

Operation
The SIDACtor operates much like a switch. In the off-state, the device exhibits leakage
currents (IDRM) less than 5µA making it invisible to the circuit it is protecting. As a
transient voltage exceeds the SIDACtors VDRM, the device will begin to enter its
protective mode with characteristics similar to an avalanche diode. When supplied with
enough current (IS), the SIDACtor will switch to an on-state, shunting the surge from
the circuit it is protecting. While in the on-state, the SIDACtor is able to sink large

amounts of current because of the low voltage drop (VT) across the device. Once the
current flowing through the device is either interrupted or falls below a minimum
holding current (IH), the SIDACtor resets, returning to its off-state.
Physics
The SIDACtor is a semiconductor device which is characterized as having four layers
of alternating conductivity; PNPN. 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 increases and exceeds the devices VDRM, 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’s current gain
exceeds unity. Once unity is exceeded, the SIDACtor switches from a high impedance
(measured at VS) to a low impedance (measured at VT) until the current flowing
through the device is reduced below it’s holding current (IH).

SIDACtor Selection Criteria
6,'$&WRUꢀ6HOHꢁWLRQꢀ&ULWHULD
When selecting a SIDACtor, the following criteria should be used:
Off-state Voltage (VDRM
)
The VDRM of the SIDACtor must be greater than the maximum operating voltage of the
circuit that the SIDACtor is protecting.
Example 1: For a POTS (Plain Old Telephone Service) application, convert the maximum
operating ring voltage (150VRMS) to a peak voltage and add the maximum DC bias
of the central office battery:
150VRMS√2 + 56.6VPK = 268.8VPK
VDRM >268.8V
Example 2: For an ISDN application, add the maximum voltage of the DC power supply to the
maximum voltage of the transmission signal:
150VPK + 3VPK = 153VPK
VDRM >153V
Switching Voltage (VS)
The VS of the SIDACtor should be equal to or less than the instantaneous peak
voltage rating of the component it is protecting.
Example 1: VS ≤ VRelay Breakdown
Example 2: VS ≤ SLIC VPK
Peak Pulse Current (IPP
)
For circuits that do not require additional series resistance, the surge current rating
(IPP) of the SIDACtor should be greater than or equal to the surge currents associated
with the lightning immunity tests of the applicable regulatory requirement (IPK).
IPP ≥ IPK
For circuits that utilize additional series resistance, the surge current rating (IPP) of the
SIDACtor should be greater than or equal to the available surge currents associated
with the lightning immunity tests of the applicable regulatory requirement (IPK(available)).
IPP ≥ IPK(available)
The maximum available surge current is calculated by dividing the peak surge voltage
(VPK) by the total circuit resistance (RTOTAL).
IPK(available) = VPK/RTOTAL
For longitudinal surges (TIP-GND, RING-GND), RTOTAL is calculated for both TIP and
RING.
RSOURCE = VPK/IPK
RTOTAL = RTIP + RSOURCE
RTOTAL = RRING + RSOURCE
Teccor Electronics

SIDACtor Selection Criteria

For metallic surges (TIP-RING):
RSOURCE = VPK/IPK
RTOTAL = RTIP + RRING + RSOURCE
Example 1: A modem manufacturer must pass the Type A surge requirement of FCC Part 68
without any series resistance.
I
PK = 100A, 10 x 560 µs
IPP ≥ 100A, 10 x 560 µs
Example 2: A line card manufacturer must pass the surge requirements of Bellcore 1089 with
30 Ω on Tip and 30 Ω on Ring.
IPK = 100A, 10 x 1000 µs
VPK = 1000V
RSOURCE = VPK/IPK = 10 Ω
RTOTAL = RSOURCE + RTIP = 40 Ω
IPK (available) = VPK/RTOTAL = 100V/40Ω
IPP ≥ 25A
Holding Current (IH)
Because FCC Part 68.306.A.6.iii specifies that registered terminal equipment not
exceed 140mA of DC current per conductor under short circuit conditions, the holding
current of the SIDACtor is set at 150mA.
For specific design criteria, the holding current (IH) of the SIDACtor must be greater
than the DC current that can be supplied during an operational and short circuit
condition.
Off-State Capacitance (CO)
Assuming that the critical point of insertion loss is 70% of the original signal value, the
SIDACtor can be used in most applications with transmission speeds of up to 30MHz.
For transmission speeds greater than 30MHz, a compensation circuit may be required.

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. In
an attempt to simplify this process, Teccor has worked with several fuse manufacturers
to compile Table 5-1.

When selecting a fuse the following criteria should be used:

Over-Voltage Protection Comparison
SIDACtor® Data Book
2YHUꢂ9ROWDJHꢀ3URWHꢁWLRQꢀ&RPSDULVRQ
There are principally four different technologies used for over-voltage protection:
Gas Discharge Tubes (GDTs), Metal Oxide Varistors (MOVs), TVS diodes, and
SIDACtors. 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.
Gas Discharge Tubes
Overview
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 break-down
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 500A for 200 impulses and capacitance ratings can be as low as 1pF with a
zero volt bias.
Restrictions
Gas tubes have a limited shelf life, their performance degrades with usage, and 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 usually used in telecommunications applications other than station protection
modules.
Metal Oxide Varistors
Overview
Metal Oxide Varistors (MOV’s) 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, MOV’s shunt transients by decreasing
their resistance as voltage is applied.
Advantages
Since MOV’s surge capabilities are determined by their physical dimensions, high
surge current ratings are available. And because MOV’s are clamping devices, they
can be used as transient protectors in secondary AC power line applications.
Restrictions
Like gas tubes, MOV’s have slow response times resulting in peak clamping voltages
which can be greater than twice the devices voltage rating (Figure 5-3). MOV’s also
have long term reliability and performance issues due to their tendency to fatigue, high
capacitance and limited packaging options.

(972)580-7777
SIDACtor® Data Book
Over-Voltage Protection Comparison
Applications
Although MOV’s are restricted from being used 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.
TVS Diodes
Overview
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. The
first is that 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. The second is that 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.
SIDACtors
Overview
A SIDACtor is a PNPN device that can be thought of as a TVS diode with a gate. Upon
exceeding its peak off-state voltage (VDRM), a SIDACtor will clamp a transient voltage
to within the devices switching voltage (VS) rating. Then, once the current flowing
through the SIDACtor exceeds its switching current, the device will crowbar and
simulate a short circuit condition. Once the current flowing through the SIDACtor is
less than the devices holding current (IH), the SIDACtor will reset and return to its high
off-state impedance.
Advantages
Advantages of the SIDACtor include its fast response time (Figure 5-3), stable
electrical characteristics, long term reliability, and low capacitance. Also, because the
SIDACtor is a crowbar device, it can not be damaged by voltage and it has extremely
high surge current ratings.
Restrictions
Because the SIDACtor is a crowbar device, it can not be used directly across the AC
line; it must be placed behind a load. Failing to do so will result in exceeding the
SIDACtors surge current rating which may cause the device to enter a permanent
short circuit condition.

Applications
Although found in other applications, SIDACtors are primarily used as the principle
over-voltage protector in telecommunications and data communications circuits. For
applications outside this realm, the design criteria on pages 5-5 and 5-6 should be
followed.

Over-Current Protection
2YHUꢂ&XUUHQWꢀ3URWHꢁWLRQꢀ
In addition to protecting against over-voltage conditions, equipment should also be
protected from over-current conditions using either PTC’s, fuses, power/line feed
resistors, or flameproof resistors. In all instances the over-current protector is a series
element placed in front of the over-voltage protector on either Tip or Ring for metallic
(closed loop) applications and on both Tip and Ring for longitudinal (grounded)
applications.
PTC’s
Overview
PTC’s 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 will increase its resistance asymptotically until the device simulates
an open, 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 PTC’s are resettable devices, they work well in a variety of industrial
applications where electrical components can not withstand multiple, low current
faults.
Restrictions
Although PTC’s 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
PTC’s are used in a variety of applications. In addition to protecting
telecommunications equipment, PTC’s are also used to prevent damage to
rechargeable battery packs, interrupt the current flow during a motor lock condition,
and limit the sneak currents that may cause damage to a 5-pin module.
Fuses
Overview
Due to their stability, fuses are one of the most popular solutions for meeting AC power
cross requirements for telecommunications equipment. Similar to PTC’s, fuses
function by reacting to the heat generated due to excessive current flow. Once the
fuses I2t rating is exceeded, the center conductor will open.
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 will only interrupt a circuit when extreme
fault conditions exist, and when coordinated properly with an over-voltage protector,
offer a very competitive and effective solution for transient immunity needs.
Teccor Electronics
(972) 580-7777
5 - 11
Over-Current Protection
SIDACtor® Data Book
Weaknesses
Because a fuse will not reset, consideration should be given to their use in applications
where multiple fault occurrences are likely. Examples such as AC strip protectors and
ground fault interrupting circuits (GFIC) are applications where an alternative solution
might be more prudent.
Applications
Telecommunications equipment that is 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.
Power/Line Feed Resistors
Overview
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 over-voltage
protectors that can not withstand the surge currents associated with applicable
regulatory requirements.
Flameproof Resistors
Overview
For cost sensitive designs, small, 1/8W - 1/4W flameproof metal film resistors are often
used in lieu of PTC’s, 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 cheap and plentiful.
Restrictions
Flameproof resistors are not resistive to transient conditions and are susceptible to
nuisance blows.
Applications
Outside of very inexpensive customer premise equipment, small resistors are rarely
used as a means to protect telecommunications equipment during power fault
conditions.

Overview
Because the interface portion of a PCB is subjected to high voltages and surge
currents, consideration should be given to the trace widths, trace separation, and
grounding.
Trace Widths
IPC-D- 275 specifies the trace widths required for various current carrying capacities.
This is very important for grounding conditions to insure 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 .025 inch trace width with 1oz. copper.

SIDACtor® Data Book
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 percent. An easy approximation can be
generated by starting with Figure 5-4 to calculate the conductor cross sectional area
required. Once this has been done, Figure 5-5 converts the cross sectional area to the
required conductor width dependent on the copper foil thickness of the trace.

Conductor Cross-Section Area (sq mils)
Trace Separation
Because Tip and Ring traces are subjected to transient conditions, they should be
routed towards the edge of the PCB away from sensitive areas, and should maintain a
minimum separation of 2.5mm between themselves and other traces. A good rule of
thumb for separation of non-coated top layer traces is to maintain spacing equal to
.010mm per volt.
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.
The first is that a large copper plane should be provided using a grid pattern for the
ground reference point.
Next, it should be decided 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 (λ = 300,000/FkHz) and a multi
point (also called distributed) grounding scheme is used for circuit trace lengths

greater than one-fourth of a wavelength.
Finally, because traces exhibit a certain level of inductance, the length of the ground
trace on the PCB should be kept 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:
1. V=L (dI/dt)
2. L=0.0051ρ [loge 2ρ/(t+w) +½ - logeG] in µH
ρ = length of trace
G = is a function thickness and width as is given below
t

w = trace width
As an example, assume circuit A is protected by a P3100SC with a VS equal to 300V
and a ground trace one inch in length and a self-inductance equal to 2.4µH/inch.
Assume circuit B has the identical characteristics as the first, except the ground trace
is 5 inches in length instead of 1 inch in length. If both circuits are surged with a 100A,
10x1000µs wave-form, the results would be as follows:

Other practices to ensure sound grounding techniques are:
1. Always cross signal grounds and earth grounds perpendicularly in order to
minimize the field effects of “noisy” power supplies.
2. Always 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 is invariably
connected first.

Overview
When placing surface mount components, a good solder bond is critical because:
1. The solder provides a thermal path in which heat is dissipated from the
packaged silicon to the rest of the board.
2. A good bond is less subject to thermal fatiguing and results in improved component
reliability.
Reflow Soldering
The preferred technique for mounting the DO-214 package is to reflow-solder the
device onto a PCB - printed circuit board. (Figure 5-6).
Figure 5-6 Reflow Soldering Procedure
1. Screen print solder paste
(or flux)
2. Place component
(allow flux to dry)
3. Reflow solder
For reliable connections, the PCB should first be screen printed with a solder paste or
fluxed with a reliable solution that is easily removed 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. 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
5 - 16

excess of 215°C, care should be taken such that the maximum temperature of the
leads does not exceed 275°C and the maximum temperature of the plastic body does
not exceed 250°C (Figure 5-8).

During reflow, the surface tension of the liquid solder will draw 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. However, if
the footprints of the pad are not concentrically aligned, the same effect can result in
undesirable shifts as well, hence the importance of using a standard contact pattern
which leaves sufficient room for self-positioning.
After the solder has cooled, 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 such 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 - 260°C and permanently affixes the component to the
PCB.
Although a popular method of soldering, wave soldering does have some drawbacks:
1. A double pass is often required to remove excess solder.
2. Solder bridging and shadows begin to occur as board density increases.
3. Wave soldering utilizes the sharpest thermal gradient.

Telecommunications Protection
7HOHꢁRPPXQLꢁDWLRQVꢀ3URWHꢁWLRQ
Overview
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.
System Transients
Telecommunications equipment connected to power and telephone cables is exposed
to system transients caused by lightning and power cross conditions.
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 by
terminating equipment and is the primary reason most regulatory agencies require
telecom equipment to have both longitudinal and metallic surge protection.
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 a
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
SIDACtor® Data Book
/LJKWQLQJ
Overview
Lightning is one of nature’s most common and dangerous phenomena. At any one
time, there are approximately 2,000 thunderstorms in progress around the globe with
lightning striking the earth over 100 times per second. During a single year in United
States, lightning will strike 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
The formation of 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.
The Formation of Lightning
Cloud to ground lightning will begin 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 will begin 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 and can rise up out of a tree, roof of a house,
or even the top of your head. 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.
The 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 500ms and 1 second.
During a lightning strike, the associated voltages range from 20,000V to 1,000,000V
while currents average around 35,000A. However, it should be noted that maximum
currents associated with lightning have been measured as high as 300,000A.

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.

Standard Terms and Conditions
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:
(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.
