SCHOTTKYRECTIFIER
HIGH EFFICIENCY SERIES
45CKQ100
45A*, 100V
Description/Features
MajorRatingsandCharacteristics
The 45CKQ100 center tap Schottky rectifier has been
expressly designed to meet the rigorous requirements
of HiRel environments. It is packaged in the hermetic
isolated TO-258AA 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.
