401CMQ... SERIES
SCHOTTKY RECTIFIER 400 Amp
TO-244AB Isolated
Major Ratings and Characteristics Characteristics
IF(AV) Rectangular waveform VRRM range IFSM VF TJ @ tp = 5 s sine @ 200 Apk, TJ = 125C (per leg) range
Description/Features
The 401CMQ center tap, high current, 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 high current switching power supplies, converters, free-wheeling diodes, welding and reverse battery protection. 175 C TJ operation 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
