Bulletin PD-20581 rev. A 07/01 408CNQ060 SCHOTTKY RECTIFIER 400 Amp TO-244AB Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM range IFSM VF TJ @ tp = 5 µs sine @200Apk, TJ=125°C (per leg) range Description/Features The 408CNQ center tap Schottky rectifier module series has been optimized for low reverse leakage at high temperature. The proprietary barrier technology allows for reliable operation up to 150 °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. 150 °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 408CNQ...
