Bulletin PD-2.274 rev. B 03/01 122NQ030 (R) 120 Amp SCHOTTKY RECTIFIER D-67 Description/Features Major Ratings and Characteristics Characteristics 122NQ030(R) Units IF(AV) Rectangular 120 A VRRM 30 V 22,500 A 0.41 V - 55 to 150 °C waveform IFSM @ tp = 5 µs sine VF @120Apk,TJ=125°C TJ range The 122NQ030 (R) 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 TJ operation Unique high power, Half-Pak module Replaces two 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 122NQ030 Lug Terminal Anode Base Cathode 122NQ030R Lug Terminal Cathode Base Anode Outline D-67 HALF PAK Module Dimensions in millimeters and (inches) www.irf.com 1 122NQ030 Bulletin PD-2.274 rev.
