Description / Features
The 35SCGQ030 center tap 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.
