Major Ratings and Characteristics Description/ Features IF(AV) Rectangular 120 A waveform VRRM range 35 to 45 V IFSM @ tp = 5 µs sine 29,000 A VF @ 120Apk, TJ=125°C 0.52 V TJ range - 55 to 150 °C Characteristics 120NQ.. Units The 120NQ...(R) high current Schottky rectifier module series 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, convert- ers, free-wheeling diodes, and reverse battery protection. 150° C T J 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 SCHOTTKY RECTIFIER 120 Amp 120NQ...(R) SERIES Bulletin PD-2.224 rev.
