Preferred 100 kW Transient Voltage
Suppressor for AIRCRAFT POWER
BUS PROTECTION
DESCRIPTION
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)
www.DataSheet4Uw.ciothm 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
APPEARANCE
FEATURES
• Available in both Unidirectional and Bidirectional
construction (Bidirectional with CA suffix)
• TVS selection for 33 to 400 V Standoff Voltages (VWM)
• 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 -55oC 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
APPLICATIONS / BENEFITS

Level 5 for Waveform 4 (6.4/69 µs) on device types
RT100KP33A or CA up to RT100KP260A or CA
• Pin injection protection per RTCA/DO-160E up to
Level 3 for Waveform 5A (40/120 µs) on all devices
• Pin injection protection per RTCA/DO-160E up to
Level 4 for Waveform 5A (40/120 µs) on device types
RT100KP33A or CA up to RT100KP64A or CA
• Consult Factory for other voltages with similar Peak
Pulse Power capabilities.

Note: High current fast rise-time transients of 250 ns or less can more than triple the VC from parasitic inductance effects (V= -Ldi/dt) compared to the
clamping voltage shown in the initial Electrical Characteristics on page 1 as also described in Figures 5 and 6 herein.
Also see MicroNotes 127, 130, and 132 on the Microsemi website (Support section) for further information on Transient
Voltage Suppressors with reference to aircraft industry specification RTCA/DO-160E.
