| Bulletin PD-20567 rev. D 08/03 40L15CW SCHOTTKY RECTIFIER 2 x 20 Amps Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM IFSM @ tp = 5 s sine VF TJ @ 19 Apk, TJ=125C (per leg, Typical) 15 700 0.25 V A V Description/ Features The 40L15CW 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. 125C 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 40L15CW Units 40 A - 55 to 125 C Case Styles 40L15CW TO-247AC www.irf.com 1 40L15CW Bulletin PD-20567 rev.
