SCHOTTKY RECTIFIER
Major Ratings and Characteristics Characteristics
IF(AV) Rectangular waveform VRRM range IFSM @ tp = 5 µs sine VF TJ @ 80 Apk, TJ = 125°C (per leg) range
160 Amp
Description/Features
The 160CMQ isolated, center tap Schottky rectifier module series has been optimized for very low forward voltage drop, with moderate leakage. The proprietary barrier technology allows for reliable operation up to 150° C junction temperature. Typical applications are in switching power supplies, converters, free-wheeling diodes, and reverse battery protection. 150° C TJ operation Isolated heatsink Center tap module High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance Very low forward voltage drop High frequency operation reliability
