Description/Features
The 1N7045T3 Schottky rectifier has been expressly designed to meet the rigorous requirements of Hirel environments. It is packaged in the hermetic isolated TO-257AA 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. Ful lMIL-PRF-19500 quality conformance testing is available on source control drawings to TX, TXV and S levels.
