Major Ratings and Characteristics IF(AV) Rectangular 240 A waveform VRRM range 80 to 100 V IFSM @ tp = 5 µs sine 25,500 A VF @ 240Apk, TJ=125°C 0.72 V TJ range - 55 to 175 °C Characteristics 243NQ... Units Description/Features 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 opera- tion up to 175° C junction temperature. Typical applications are in switching power supplies, converters, free-wheeling diodes, and reverse battery protection. 175° 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 Low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability SCHOTTKY RECTIFIER 240 Amp 243NQ...(R) SERIES Bulletin PD-2.262 rev.
