DESCRIPTION
APPEARANCE
Microsemi’s 65 kW bidirectional Transient Voltage Suppressors (TVSs)
protects 28 volt dc airborne electronic equipment from harsh lightning
environments per RTCA/DO-160E Section 22 and is compatible with
Section 16, paragraph 16.6.2.4 Category A for 46.3 V, Category B for 60 V,
and Category Z for 80 V high-line surges. It is also optionally available with
screening in accordance with MIL-PRF-19500 or avionics screening as
described in the Features section. It is also available as RoHS Compliant
(annealed matte-Tin finish) with an e3 suffix added to the part number.
Microsemi also offers a broad spectrum of other TVSs to meet your needs.
IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
FEATURES
APPLICATIONS / BENEFITS
Unidirectional TVS construction with A suffix or
bidirectional with a CA suffix
Suppresses transients up to 65 kW @ 6.4/69 μs
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 +125oC (10X), surge (3X) in
each direction, 24 hours HTRB in each direction, and post
test (VBR and ID)
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.
Moisture classification is Level 1 with no dry pack required
per IPC/JEDEC J-STD-020B.
RoHS Compliant devices available by adding “e3” suffix
Pin injection protection per RTCA/DO-160E up to Level
5 for Waveform 4 (6.4/69 s) and up to Level 3 for
Waveform 5A (40/120
μs) at 70oC
Compatible with “abnormal surge voltage (dc)” in
16.6.2.4 (Category A, B, and Z) of RTCA/DO-160E
The RTCA65KP48A is designed for Category A in
protecting 80V components**
The RTCA65KP54A or 60A is designed for Category B
in protecting 90V or 100 V components**
The RTCA65KP75A is designed for Category Z in
protecting 125 V components**
Consult Factory for other voltages with similar Peak
Pulse Power capabilities.
**includes switching transistors, MOSFETs & IGBTs
in off-line switching power supplies
