Description/Features
The 10YQ045 Schottky rectifier has been expressly
designed to meet the rigorous requirements of hi-rel
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. Full MIL-PRF-19500 quality conformance
testing is available on source control drawings to TX, TXV
and S levels.
