1 / 4 page Preferred 100 kW Transient Voltage Suppressor for AIRCRAFT POWER BUS PROTECTION S C O T TS DALE DIVISION 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. IMPORTANT: For the most current data, consult MICROSEMI’s website: http://www.microsemi.com FEATURES APPLICATIONS / BENEFITS • Available in both Unidirectional and Bidirectional construction (Bidirectional with CA suffix) • TVS selection for 33 to 400 V Standoff Voltages (V WM) • 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 -55 oC 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 • Protection from high power switching transients, induced RF, and lightning threats with comparatively small package size (0.25 inch diameter) • Protection from ESD and EFT per IEC61000-4-2 and IEC61000-4-4 • Pin injection protection per RTCA/DO-160E up to Level 4 for Waveform 4 (6.4/69 µs) on all devices • Pin injection protection per RTCA/DO-160E up to 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. MAXIMUM RATINGS MECHANICAL & PACKAGING • Peak Pulse Power dissipation at 25ºC: 100 kW at 6.4/69 µs waveform in Figure 8 (also see figures 1 and 2) • Impulse repetition rate: 0.005% • tclamping (0 volts to VBR min): <100 ps theoretical for unidirectional and <5 ns for bidirectional • Operating & storage temperatures: -65 oC to +150oC • Thermal resistance: 17.5C/W junction to lead, or 77.5C/W junction to ambient when mounted on FR4 PC board with 4 mm 2 copper pads (1 oz ) and track width 1 mm, length 25 mm • Steady-state power dissipation: 7 Watts @ TL = 27.5 oC or 1.61 Watts at TA =25 oC when mounted on FR4 PC Board described for thermal resistance above • Forward surge: 250 Amps 8.3 ms half-sine wave for unidirectional devices only • Solder Temperatures: 260 oC for 10 s maximum • CASE: Void free transfer molded thermosetting epoxy meeting UL94V-O requirements • FINISH: Tin-Lead or RoHS Compliant matte-Tin plating solderable per MIL-STD-750, method 2026 • Polarity: Cathode marked with band for unidirectional (no band required for bi-directional) • MARKING: Manufacturers logo and part number. Add prefix MA, MQ, MX, etc., for screened parts. • WEIGHT: 1.7 grams (approximate) • TAPE & REEL option: Standard per EIA-296 for axial package (add “TR” suffix to part number) • Package dimensions: See last page Microsemi Scottsdale Division Page 1 Copyright © 2007 10-03-2007 Rev B 8700 E.
