Preferred 100 kW Transient Voltage Suppressor for AIRCRAFT POWER BUS PROTECTION WWW.Microsemi .COM SCOTTSDALE DIVISION RT100KP33A thru RT100KP400CA, e3 RT100KP33A – 400CA, 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 o r 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.

Clamping voltage does not include any variable parasitic lead inductance effects observed during the 6.4 µs rise time due to lead length. 3. The Maximum Peak Pulse Current (IPP) shown represents the performance capabilities by design. * Surge test screening is only performed up to 900 Amps (test equipment limitations). 4.
