B 03/02 20CTQ150 20CTQ150S 20CTQ150-1 SCHOTTKY RECTIFIER 20 Amp Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM IFSM @ tp = 5 s sine VF TJ @ 10 Apk, TJ = 125C (per leg) range Description/Features Units A V A V This center tap Schottky ectifier has been optimized for low reverse leakage at high temperature. The proprietary barrier technology allows for reliable operation up to 175 C junction temperature. Typical applications are in switching power supplies, converters, free-wheeling diodes, and reverse battery protection. 175 C TJ operation Center tap configuration 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 20 150 1030 0.66 - 55 to 175 C Case Styles 20CTQ150 20CTQ150S 20CTQ150-1 Base Common Cathode 2 Base Common Cathode 2 Base Common Cathode 2 1 Anode 2 Common Cathode 3 1 Anode Anode 2 Common Cathode 3 1 Anode Anode 2 Common Cathode 3 Anode TO-220AB D2PAK TO-262 www.irf.com 1 20CTQ150, 20CTQ150S, 20CTQ150-1 Bulletin PD-20648 rev.
