Bulletin PD-20849 rev. A 05/06 40CTQ045PbF SCHOTTKY RECTIFIER 40 Amp IF(AV) = 40Amp VR = 45V Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM IFSM @ tp = 5 μs sine VF TJ @ 20 Apk, TJ = 125°C (per leg) range Description/ Features Units A V A V This center tap 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 Center tap configuration Very low forward voltage drop 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 40 45 1240 0.48 - 55 to 150 °C Case Styles 40CTQ045PbF Base Common Cathode 2 1 Anode 2 Common Cathode 3 Anode TO-220 www.irf.com 1 40CTQ045PbF Bulletin PD-20849 rev.
