Bulletin PD-20593 rev. B 03/03 MBR340 SCHOTTKY RECTIFIER 3.0 Amp Description/ Features Major Ratings and Characteristics Characteristics MBR340 Units IF(AV) Rectangular 3.0 A 30/40 V IFSM @ tp = 5 s sine 430 A VF 0.6 V - 40 to 150 C waveform VRRM @ 3 Apk, TJ = 25C TJ The MBR340 axial leaded Schottky rectifier has been optimized for very low forward voltage drop, with moderate leakage. Typical applications are in switching power supplies, converters, free-wheeling diodes, and reverse battery protection. Low profile, axial leaded outline 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 CASE STYLE AND DIMENSIONS Outline C - 16 Dimensions in millimeters and inches www.irf.com 1 MBR340 Bulletin PD-20593 rev.
