PD-20354E
SCHOTTKY RECTIFIER
HIGH EFFICIENCY SERIES
25GQ045
35Amp, 45V
Description/Features
The 25GQ150 Schottky rectifier has been expressly
designed to meet the rigorous requirements of HiRel
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.
