Bulletin PD-20044 rev. B 09/01 85CNQ015A SCHOTTKY RECTIFIER New GenIII D-61 Package Major Ratings and Characteristics Characteristics IF(AV) Rectangular VRRM IFSM @ tp = 5 µs sine VF TJ @ 40 Apk, TJ= 75 °C (per leg) range 80 Amp Description/Features The 85CNQ015A 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 85CNQ015A Units 80 waveform 15 5200 0.32 V A V A - 55 to 100 °C New fully transfer-mold low profile, small footprint, high current package Case Styles 85CNQ...A 85CNQ...ASM 85CNQ...ASL D61-8 www.irf.com D61-8-SM D61-8-SL 1 85CNQ015A Bulletin PD-20044 rev.
