PD-20720 12/99 189NQ... SERIES SCHOTTKY RECTIFIER 180 Amp Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM range IFSM @ tp = 5 s sine VF TJ @ 180Apk, TJ=125C range Description/Features Units A V A V C The 189NQ high current Schottky rectifier module series has been optimized for low reverse leakage at high temperature. The proprietary barrier technology allows for reliable operation up to 175 C junction temperature. Typical applications are in switching power supplies, converters, free-wheeling diodes, and reverse battery protection. 175 C TJ operation Unique high power, Half-Pak module Replaces three parallel DO-5's Easier to mount and lower profile than DO-5's High purity, high temperature epoxy encapsulation for enhanced mechanical strength and moisture resistance Low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability 189NQ... 180 135 to 150 15000 0.74 - 55 to 175 CASE STYLE AND DIMENSIONS Outline HALF PAK Module Dimensions in millimeters and inches www.irf.com 1 189NQ...
