| PD-2.328 rev. A 12/97 SD41 SCHOTTKY RECTIFIER 30 Amp Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRWM IFSM @ 60Hz VF TJ @ 60Apk, T J = 150C 35/45 600 0.70 - 65 to 150 V Description/Features Units A The SD41 Schottky rectifier 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 A V C Very low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability Hermetic packaging SD41 30 CASE STYLE AND DIMENSIONS Conforms to JEDEC Outline DO-203AA (DO-4) Dimensions in millimeters and inches www.irf.com 1 SD41 PD-2.328 rev.
