Technical content

The 75HQ Schottky rectifier 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 switching power supplies, converters, free-wheeling diodes, and re- verse battery protection. 175 °C T J operation Low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability Hermetic packaging IF(AV) Rectangular 75 A waveform V RRM range 30 to 45 V IFSM @ tp = 5 µs sine 9000 A VF @ 75 Apk, TJ = 125°C 0.63 V TJ range - 65 to 175 °C Major Ratings and Characteristics Characteristics 75HQ...
