Bulletin PD-2.249 rev. C 05/02 121NQ...(R) SERIES SCHOTTKY RECTIFIER 120 Amp D-67 Major Ratings and Characteristics Characteristics IF(AV) Rectangular waveform VRRM range IFSM @ tp = 5 µs sine VF TJ @ 120Apk, TJ=125°C range Description/Features The 121NQ... (R) 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 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 Low forward voltage drop High frequency operation Guard ring for enhanced ruggedness and long term reliability 121NQ...(R) Units 120 35 to 50 19,800 0.56 - 55 to 175 A V A V °C 123NQ100 Lug Terminal Anode Base Cathode 123NQ100R Lug Terminal Cathode Base Anode Outline D-67 HALF PAK Module Dimensions in millimeters and (inches) www.irf.com 1 121NQ...(R) Series Bulletin PD-2.249 rev.
