DESCRIPTION
APPEARANCE
Microsemi’s 100 kW Transient Voltage Suppressors (TVSs) are designed
for aircraft applications requiring high power transient protection with a
comparatively small axial-leaded package size.
This includes various
threats such as “Waveform 4” at 6.4/69 s per RTCA/DO-160E Section 22.
It is also available with screening in accordance with MIL-PRF-19500 or
avionics screening as described in the Features section herein. It may also
be optionally acquired with 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
Available in both Unidirectional and Bidirectional
construction (Bidirectional with CA suffix)
TVS selection for 33 to 400 V Standoff Voltages (V
WM)
Suppresses transients up to 100 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, and JANTXV are also available by adding
MQ, MX, or MV 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
