Major Ratings and Characteristics Description/Features 7/13/01 CASE STYLE IR Case Style TO-254AA www.irf.com 1 Characteristics 35GQ100 Units IF(AV) 35 A VRRM 100 V IFSM @ tp = 8.3ms half-sine 270 A VF @ 35Apk, TJ =125°C 1.0 V TJ,Tstg Operating and storage -55 to 150 °C HIGH EFFICIENCY SERIES The 35GQ100 Schottky rectifier has been expressly designed to meet the rigorous requirements of hi-rel environments. It is packaged in the hermeticly isolated TO-254AA package. The device's forward voltage drop and reverse leakage current are optimized for the lowest power loss and the highest circuit efficiency for typical high frequency switching power supplies and resonent power converters. Full MIL-PRF-19500 quality conformance testing is available on source control drawings to TX, TXV and S quality levels.
