SERIES SCHOTTKY RECTIFIER 400 Amp TO-244AB Isolated Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM range IFSM VF TJ @ tp = 5 µs sine @200Apk, TJ=125°C (per leg) range Description/Features The 400CMQ high current 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, welding, and reverse battery protection. 150 °C TJ operation Center tap module - Isolated Base High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance Very low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability 400CMQ...
