AIRCRAFT AC POWER BUS PROTECTION
DESCRIPTION
Microsemi’s 200 kW bidirectional Transient Voltage Suppressor (TVS)
protects 120 volt ac airborne electronic equipment from harsh lightning
environments per RTCA/DO-160D Section 22 and is compatible with
Section 16 for 180 volt ac 100 ms highline surges. Microsemi also
offers a broad spectrum of other TVS products to meet your needs.

APPEARANCE
FEATURES
• Symmetrical bidirectional TVS construction
• Available as either low clamp with “CVCL” suffix or
normal clamping features with “CA” suffix.
• Suppresses transients up to 200 kW @ 10/40 us
• 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 +125^oC
(10X), surge (3X) in each direction, 24 hours HTRB
in each direction, and post test (V_Z and I_R)
• Options for screening in accordance with MIL-
PRF-19500 for JAN JANTX, JANTXV, and JANS
are also available by adding MQ, MX, MV, or MSP
prefixes respectively to part numbers
• Moisture classification is Level 1 with no dry pack
required per IPC/JEDEC J-STD-020B
APPLICATIONS / BENEFITS
• Pin injection protection per RTCA/DO-160D up to
Level 4 for Waveform 4 (6.4/69 µs) and Level 3 for
Waveform 5A (40/120 μs)
• Compatible with “abnormal surge and variation from a
controlled steady-state level” as described in 16.5.3.3
of RTCA/DO-160D.
• The 200KP295CVCL is designed for low clamping
protection of 400V transistors, MOSFETs and IGBTs
in off-line switching power supplies.
• The 200KP295CA normal clamp device is for use in
less sensitive applications including RFI/EMI filters
and general across-the-line protection.
• Secondary lightning protection per IEC61000-4-5 with
12 Ohms source impedance for Class 1,2, 3 and 4
• Secondary lightning protection per IEC61000-4-5 with
2 Ohms source impedance for Class 2 and 3
MAXIMUM RATINGS
• Steady-state power dissipation: 7 W @ T_A = 25^oC
• Peak Pulse Power at 25^oC: 200 kW at 10/40 µs
(linear derate to zero @ 150^oC)
• Repetition rate: 0.01% max.
• Operating & storage temperatures: -55^oC to +150^oC
