The 80SCLQ045 center tap Schottky rectifier has been
expressly designed to meet the rigorous requirements of hirel environments. It is packaged in the hermetic surface
mount SMD-1 ceramic 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.
