| Bulletin PD-20724 rev. B 10/02 409DMQ... Series SCHOTTKY RECTIFIER 400 Amp TO-244AB isolated doubler Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM IFSM @ tp = 5 s sine VF TJ @ 200Apk, TJ=125C (per leg) range 135 to 150 25,500 0.72 V A V Description/ Features The 409DMQ 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 409DMQ...
