PD-2.247 rev. A 12/97 85HQ... SERIES SCHOTTKY RECTIFIER Amp Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM range IFSM @ tp = 5 µs sine VF TJ @ 85 Apk, TJ=125°C range 35 to 45 9000 0.62 - 65 to 175 V Description/Features Units A The 85HQ 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 reverse battery protection. 175°C TJ operation A V °C Low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability Hermetic packaging 85HQ... 85 CASE STYLE AND DIMENSIONS Conforms to JEDEC Outline DO-203AB (DO-5) Dimensions in millimeters and inches www.irf.com 1 85HQ...
