| Bulletin PD-2.060 rev. F 03/03 50SQ... SERIES SCHOTTKY RECTIFIER 5 Amp Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM range IFSM @ tp = 5 s sine VF TJ @ 5 Apk, TJ = 125C range Description/ Features Units A V A V C The 50SQ... axial leaded Schottky rectifier series has been optimized for low reverse leakage at high temperature. The proprietary barrier technology allows for reliable operation up to 175C junction temperature. Typical applications are in switching power supplies, converters, free-wheeling diodes, and reverse battery protection. 175 C TJ operation 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 50SQ... 5 60 to 100 1900 0.52 - 55 to 175 CASE STYLE AND DIMENSIONS Conforms to JEDEC Outline DO - 204AR Dimensions in millimeters and inches www.irf.com 1 50SQ...
