Bulletin PD-2.222 rev. C 12/01 90SQ... SERIES SCHOTTKY RECTIFIER 9 Amp Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM range IFSM @ tp = 5 µs sine VF TJ @ 9 Apk, TJ = 125°C range Description/Features Units A V A V °C The 90SQ axial leaded Schottky rectifier series has been optimized for very low forward voltage drop, with moderate leakage. The proprietary barrier technology allows for reliable operation up to 150°C junction temperature. Typical applications are in switching power supplies, converters, freewheeling diodes, and reverse battery protection. 150° C TJ operation High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance Very low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability 90SQ... 9 35 to 45 2150 0.42 - 55 to 150 CASE STYLE AND DIMENSIONS Conforms to JEDEC Outline DO - 204AR Dimensions in millimeters and inches www.irf.com 1 90SQ...
