Bulletin PD-2.293 rev. B 05/02 181NQ...(R) SERIES SCHOTTKY RECTIFIER 180 Amp D-67 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 181NQ high current Schottky rectifier module series has been optimized for very low forward voltage drop, with moderate leakage. The proprietary barrier technology allows for reliable operation up to 175 C junction temperature. Typical applications are in switching power supplies, converters, freewheeling 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 Very low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term 181NQ... 180 30 to 45 22,000 0.56 - 55 to 175 181NQ045 Lug Terminal Anode Base Cathode 181NQ045R Lug Terminal Cathode Base Anode Outline D-67 HALF PAK Module Dimensions in millimeters and (inches) www.irf.com 1 181NQ...(R) Series Bulletin PD-2.293 rev.
