C 12/01 40CTQ045 40CTQ045S 40CTQ045-1 SCHOTTKY RECTIFIER 40 Amp Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM IFSM @ tp = 5 s sine VF TJ @ 20 Apk, TJ = 125C (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 Values 40 45 1240 0.48 - 55 to 150 C Case Styles 40CTQ... 40CTQ...
