Description/Features
The 60LQ045 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
resonant power convertors. Full MIL-PRF-19500 quality
conformance testing is availble on control drawings to
TX, TXV and S quality levels.
