| PD-2.330 rev. A 12/97 SD241 SCHOTTKY RECTIFIER 60 Amp Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM IFSM @ 60Hz VF TJ @ 30Apk, TJ = 25C (per leg) 35/45 400 0.82 V A V Description/Features Units A The SD241 center tap Schottky rectifier 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 Center tap TO-3 package Low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability Hermetic packaging SD241 60 - 55 to 175 C CASE STYLE AND DIMENSIONS Conforms to JEDEC Outline TO-204AA (TO-3) Dimensions in millimeters and inches www.irf.com 1 SD241 PD-2.330 rev.
