IF(AV) Rectangular 200 A waveform VRRM range 80 to 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 Characteristics 203DNQ... Units Major Ratings and Characteristics The 203DNQ 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 T J 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 Description/ Features Modified JEDEC Outline TO-244AB Dimensions in millimeters and (inches)
