Bulletin PD-20793 rev. A 11/06 40L15CWPbF SCHOTTKY RECTIFIER 2 x 20 Amps IF(AV) = 40Amp VR = 15V Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM IFSM @ tp = 5 μs sine VF TJ @ 19 Apk, TJ=125°C Description/ Features Units A V A V The 40L15CWPbF center tap 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, converters, reverse battery protection, and redundant power subsystems. 125°C TJ operation (VR < 5V) Center tap module Optimized for OR-ing applications 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 ("PbF" suffix) Values 40 15 700 0.25 (per leg, Typical) - 55 to 125 °C Case Styles Base Common Cathode 2 1 3 2 Anode 1 Anode 2 TO-247AC Common Cathode www.irf.com 1 40L15CWPbF Bulletin PD-20793 rev.
