SCHOTTKY RECTIFIER Bulletin PD-20579 rev. C 02/04 203DMQ... SERIES 200 Amp Major Ratings and Characteristics Characteristics 203DMQ... Units IF(AV) Rectangular waveform VRRM range 200 A 80 and 100 V IFSM @ tp = 5 µs sine 16,000 A VF @ 100Apk, TJ=125°C 0.70 V (per leg) TJ range - 55 to 175 °C TO-244AB isolated doubler Description/ Features The 203DMQ Schottky rectifier doubler 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, plating power supplies, UPS systems, converters, free-wheeling diodes, welding, and reverse battery protection. 175 °C TJ operation 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 www.irf.com 1 3 2 Modified JEDEC Outline TO-244AB Isolated Dimensions in millimeters and (inches) 1 203DMQ...
