Bulletin PD-2.262 rev. B 05/02 243NQ...(R) SERIES SCHOTTKY RECTIFIER 240 Amp D-67 Major Ratings and Characteristics Description/Features Characteristics 243NQ... Units IF(AV) Rectangular 240 A 80 to 100 V 25,500 A 0.72 V - 55 to 175 C waveform VRRM range IFSM @ tp = 5 s sine VF @ 240Apk, TJ=125C TJ range The 243NQ 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 four 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 243NQ100 Lug Terminal Anode Base Cathode 243NQ100R Lug Terminal Cathode Base Anode Outline D-67 HALF PAK Module Dimensions in millimeters and (inches) www.irf.com 1 243NQ...(R) Series Bulletin PD-2.262 rev.
