Description/Features
The 25GQ045 Schottky rectifier has been expressly
designed to meet the rigorous requirements of hi-rel
environments. It is packaged in the hermetic 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 controlled drawings to TX,
TXV and S levels.
