| Bulletin PD-20593 rev. A 03/02 MBR340 SCHOTTKY RECTIFIER 3.0 Amp Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM IFSM VF TJ @ tp = 5 s sine @ 3 Apk, TJ = 25C Description/Features Units A V A V C 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 MBR340 3.0 30/40 430 0.6 - 40 to 150 CASE STYLE AND DIMENSIONS Outline C - 16 Dimensions in millimeters and inches www.irf.com 1 MBR340 Bulletin PD-20593 rev.
