DESCRIPTION

APPEARANCE

Microsemi’s RT130KP275 and RT130KP295 bidirectional 130 kW

Transient Voltage Suppressors (TVSs) protects 120 volt ac airborne

electronic equipment from harsh lightning per RTCA/DO-160E Section 22

and is compatible with Section 16 for 180 volt ac 100 ms highline surges

(paragraph 16.5.2.3.1b). Microsemi also offers a broad spectrum of other

TVS products to meet your needs.

IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com

FEATURES

APPLICATIONS / BENEFITS

•

Symmetrical bidirectional TVS construction

• Pin injection protection per RTCA/DO-160E Table 22-2

up to Level 5 for Waveform 4 (6.4/69 µs) and Level 3

for Waveform 5A (40/120 μs) at 70^oC

Two Working Standoff Voltages of 275 V and 295 V

Available as either low clamp with “CV” suffix or normal

clamping features with “CA” suffix.

• Compatible with “abnormal surge voltage” as

described in 16.5.2.3.1b of RTCA/DO-160E

•

Suppresses transients up to 130 kW @ 6.4/69 µs

• The very low clamping with “CV” suffix is designed for

low clamping protection of 400V transistors, IGBTs

and MOSFETs in off-line switching power supplies.

Fast response with less than 5 ns turn-on time.

Optional 100% screening for avionics grade is available

by adding MA prefix to part number for added 100%

temperature cycle -55^oC to +125^oC (10X), surge (3X) in

each direction, 24 hours HTRB in each direction, and post

test (V_Zand I_R)

• The normal clamp device with “CA” suffix is for use in

less-sensitive applications including RFI/EMI filters

and general across-the-line protection.

• Consult Factory for other voltages with similar Peak

•

Options for screening in accordance with MIL-PRF-19500

for JAN JANTX, JANTXV, and JANS are also available by

adding MQ, MX, MV, or MSP prefixes respectively to part

numbers

Pulse Power capabilities.

• Secondary lightning protection per IEC61000-4-5 with

12 Ohms source impedance for Class 1,2, 3 and 4

• Secondary lightning protection per IEC61000-4-5 with

•

Moisture classification is Level 1 with no dry pack required

per IPC/JEDEC J-STD-020B

2 Ohms source impedance for Class 2 and 3

• Consult Factory for other voltages with similar Peak

RoHS Compliant devices available by adding “e3” suffix

NOTE 2: Also equivalent to 90 and 87 Amps (40 kW) respectively at a longer impulse of 10/1000 μs (see Figure 1) with clamping voltages

shown. Also see other equivalent peak pulse power performance levels for aircraft waveforms on page 3 for this device.

NOTE: This P_PPvs. Time graph allows the designer to use these

parts over a broad power spectrum using the guidelines illustrated

in App Note 104 on Microsemi’s website. Aircraft transients are

described with exponential decaying waveforms. For suppression

of square waveforms, derate power and current to 66% of that for

exponential decay.

INSTALLATION

TVS devices used across power lines are

Correct

Wrong

subject to relatively high magnitude surge

currents and are more prone to adverse

parasitic inductance effects in the mounting

leads. Minimizing the shunt path of the lead

inductance and their V= -Ldi/dt effects will

optimize the TVS effectiveness. Examples

of optimum installation and poor installation

are illustrated in figures 3 through figure 6.

FIGURE 3

FIGURE 5

Figure

illustrates minimal parasitic

inductance with attachment at end of device.

Inductive voltage drop is across input leads.

Virtually no “overshoot” voltage results as

illustrated with figure 4.

The loss of

effectiveness in protection caused by

excessive parasitic inductance is illustrated

in figures 5 and 6. Also see MicroNote 111

for further information on “Parasitic Lead

Inductance in TVS”.

Note: High current fast rise-time transients of 250 ns or less can more than triple the V_Cfrom parasitic inductance effects (V= -Ldi/dt) compared to the

clamping voltage shown in the initial Electrical Characteristics on page 1 as also described in Figures 5 and 6 herein.
