Dimensions in millimeters and inches Outline HALF PAK Module CASE STYLE AND DIMENSIONS Major Ratings and Characteristics Description/Features 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 IF(AV) Rectangular 180 A waveform VRRM range 135 to 150 V IFSM @ tp = 5 µs sine 15000 A VF @ 180Apk, TJ=125°C 0.74 V TJ range - 55 to 175 Characteristics 189NQ...
