Bulletin PD-2.249 rev. D 05/05 121NQ...(R) SERIES SCHOTTKY RECTIFIER 120 Amp IF(AV) = 120 A VR = 35/ 50V Major Ratings and Characteristics Description/ Features Characteristics Values Units IF(AV) Rectangular 120 A VRRM range 35 / 50 V IFSM @ tp = 5 s sine 19,800 A VF @ 120Apk, TJ=125C 0.56 V TJ range - 55 to 175 C waveform 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 Case Styles 121NQ...(R) D-67 Document Number: 93209 www.vishay.com 1 121NQ...(R) Series Bulletin PD-2.249 rev.
