Features, Applications

IF(AV) Rectangular waveform VRRM range IFSM 5 s sine 180Apk, TJ=125C range

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 175 C junction temperature. Typical applications are in switching power supplies, converters, free-wheeling diodes, and reverse battery protection. 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
