A 06/06 MBRB7..PbF SCHOTTKY RECTIFIER 7.5 Amp IF(AV) = 7.5Amp VR = 35 - 45V Major Ratings and Characteristics Characteristics IF(AV) VRRM IFSM VF TJ @ tp = 5 s sine @ 7.5 Apk, TJ = 125C range Rectangular waveform 35 - 45 690 0.57 - 65 to 150 V A V C Description/ Features Units A The MBRB7.. Schottky rectifier has been optimized for low reverse leakage at high temperature. 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 High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance High frequency operation Guard ring for enhanced ruggedness and long term reliability Lead-Free ("PbF" suffix) Values 7.5 Case Styles Base Cathode 2 1 3 N/C Anode D2PAK www.irf.com 1 MBRBB7..PbF Series Bulletin PD-21048 rev.
