SCHOTTKY RECTIFIER
HIGH EFFICIENCY SERIES
30LJQ100
30 Amp, 100V
Major Ratings and Characteristics
Description/Features
The 30LJQ100 Schottky rectifier has been expressly
designed to meet the rigorous requirements of hi-rel
environments. It is packaged in the hermetic surface mount
SMD-0.5 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.
