Description/Features
The 60LQ045 Schottky rectifier has been expressly
designed to meet the rigorous requirements of high
reliability 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.
