47CTQ020PBF Datasheet | International Rectifier

Description / Features Units A V A V °C This center tap Schottky rectifier has been optimized for ultra low forward voltage drop specifically for 3.3V output power supplies. The proprietary barrier technology allows for reliable operation up to 150 °C junction temperature. Typical applications are in parallel switching power supplies, converters, reverse battery protection, and redundant power subsystems. 150 °C TJ operation Values 40 20 1000 0.34 - 55 to 150 Center tap configuration Optimized for 3.3V application Ultra low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance Lead-Free ("Pb F" suffix) Case Styles Base mon Cathode Anode 2 mon Cathode Anode TO-220 .irf. 47CTQ020Pb F Bulletin PD-20854 rev.
