HIGH EFFICIENCY SERIES
Case Outline and Dimensions - LCC-18
The 8EQ045 Schottky rectifier has been expressly
designed to meet the rigorous requirements of hi-rel
environments. It is packaged in the hermetic isolated
LCC-18 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.
