GiR Rectifier 120NQ...(R) SERIES
SCHOTTKY RECTIFIER 120 Amp
Major Ratings and Characteristics Description/Features
The 120NQ...(R) high currentSchottky rectifier module series
Characteristics 120NQ...(R) Units has been optimized for very low forward voltage drop, with
moderate leakage. The proprietary barriertechnology allows for
reliable operation up to 150° C junction temperature. Typical
applications are in switching powersupplies, converters, free-
wheeling diodes, and reverse battery protection.
VRRM range 35 to 45 V . 150° C T J operation
. Unique high power, Half-Pak module
