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. IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com
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 -55oC to +125oC (10X), surge (3X) in each direction, 24 hours HTRB in each direction, and post test (VZ and IR) 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 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
