Technical content

The 409CNQ 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 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 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 Description/FeaturesMajor Ratings and Characteristics IF(AV) Rectangular 400 A waveform VRRM range 135 to 150 V IFSM @ tp = 5 µs sine 20000 A VF @ 200Apk, TJ=125°C 0.72 V (per leg) TJ range - 55 to 175 °C Characteristics 409CNQ...
