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.

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 70oC
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 -55oC to +125oC (10X), surge (3X) in
each direction, 24 hours HTRB in each direction, and post
test (VZ and IR)
• 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, and JANTXV are also available by adding
MQ, MX, or MV 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
•
•
Moisture classification is Level 1 with no dry pack required
per IPC/JEDEC J-STD-020B
• Secondary lightning protection per IEC61000-4-5 with
2 Ohms source impedance for Class 2 and 3
RoHS Compliant devices available by adding “e3” suffix
• Consult Factory for other voltages with similar Peak
Pulse Power capabilities
MAXIMUM RATINGS

NOTE 1: See MicroNote 108 for lower Clamping Voltage performance at reduced IP values relative to IPP and PPP ratings and Figure 1.
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.
