Description/Features
The 20CLQ045 center tap Schottky rectifier has been
expressly designed to meet the rigorous requirements of
hi-rel 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 controlled
drawings to TX, TXV and S levels.
