RT100KP33A thru RT100KP400CA, e3

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.
