SCHOTTKY RECTIFIER 20 Amps 20L15TPbF Bulletin PD-20844 09/04 1www.irf.com IF(AV) Rectangular 20 A waveform VRRM 15 V IFSM @ tp = 5 µs sine 700 A VF @ 19 Apk, TJ=125°C 0.25 V ( Typical) TJ range - 55 to 125 °C Characteristics Values Units Major Ratings and Characteristics The Schottky rectifier module has been optimized for ultra low forward voltage drop specifically for the OR-ing of parallel power supplies. The proprietary barrier technology allows for reliable operation up to 125 °C junction temperature. Typical applications are in parallel switching power supplies, convert- ers, reverse battery protection, and redundant power sub- systems. 125°C T J operation (VR < 5V) Single diode configuration Optimized for OR-ing applications Ultra low forward voltage drop Guard ring for enhanced ruggedness and long term reliability High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance Lead-Free ("PbF" suffix) Description/ Features Case Styles TO-220AC 20L15TPbF Anode 1 3 Cathode Base Cathode IF(AV) = 20Amp VR = 15V
