Description/Features
The 1N7041CCU1 center tap Schottky rectifier has been
expressly designed to meet the rigorous requirements of
high reliabilty 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.
