| PD-2.174 rev. B 12/97 161CMQ... SERIES SCHOTTKY RECTIFIER Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM range IFSM @ tp = 5 s sine VF TJ @ 80 Apk, TJ = 125C (per leg) range - 55 to 175 C 35 to 45 11,500 0.63 V A V 160 Amp Description/Features The 161CMQ isolated, center tap Schottky rectifier module series has been optimized for low reverse leakage at high temperature. The proprietary barrier technology allows for reliable operation up to 175 C junction temperature. Typical applications are in switching power supplies, converters, free-wheeling diodes, and reverse battery protection. 175 C T J operation Isolated heatsink Center tap module High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance Low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability Low profile, high current package 161CMQ...
