SCHOTTKY RECTIFIER 240 Amp 242NQ030 PD-2.281 rev. A 12/97 1www.irf.com Dimensions in millimeters and inches Outline HALF PAK Module CASE STYLE AND DIMENSIONS Major Ratings and Characteristics IF(AV) Rectangular 240 A waveform VRRM 30 V IFSM @ tp = 5 µs sine 27,000 A VF @ 240Apk, TJ=125°C 0.42 V TJ range - 55 to 150 °C Characteristics 242NQ030 Units The 242NQ030 high current Schottky rectifier module has been optimized for very low forward voltage drop, with moderate leakage. The proprietary barrier technology allows for reliable operation up to 150° C junction temperature. Typical applications are in switching power supplies, converters, free- wheeling diodes, and reverse battery protection. 150° C T J 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 Very low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability Description/Features
