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 µs 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.
