| Bulletin PD-2.021 rev. E 11/02 51HQ... SERIES SCHOTTKY RECTIFIER 60 Amp TO-203AB (DO-5) Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM range IFSM @ tp = 5 s sine VF TJ @ 60 Apk, TJ = 125C range 35 to 45 10,800 0.58 - 65 to 150 V A V C Description/ Features Units A The 51HQ 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, free-wheeling diodes, and reverse battery protection. 150 C TJ operation Very low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability Hermetic packaging 51HQ... 60 Conforms to JEDEC Outline DO-203AB (DO-5) Dimensions in millimeters and (inches) www.irf.com 1 51HQ...
