IF(AV) Rectangular 400 A waveform VRRM range 35 to 45 V IFSM @ tp = 5 µs sine 29,000 A VF @ 200Apk, TJ=125°C 0.52 V (per leg) TJ range - 55 to 150 °C Characteristics 400DMQ... Units Major Ratings and Characteristics Description/ Features The 400DMQ high current, Schottky rectifier doubler 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, convert- ers, free-wheeling diodes, welding, and reverse battery protection. 150 °C T J operation 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 SCHOTTKY RECTIFIER 400 Amp 400DMQ...
