| Bulletin PD 2.271 rev. C 02/01 85CNQ015 SCHOTTKY RECTIFIER 80 Amp Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM IFSM VF TJ @ tp = 5 s sine @ 40 Apk, TJ= 75 C (per leg) range Description/Features Units A V A V The 85CNQ015 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 Low profile, small footprint, high current package 85CNQ015 80 15 5200 0.32 - 55 to 125 C Case Styles 85CNQ015 85CNQ015SM 85CNQ015SL D61-8 D61-8-SM D61-8-SL www.irf.com 1 85CNQ015 Bulletin PD-2.271 rev.
