Description

The 400DMQ high current, Schottky rectifier doubler module series has been optimized for very low forward voltage drop,with moderate leakage. The proprietary barrier technology allows for reliable operation up to 150 °C junction temperature.Typical applications of the 400DMQ are in switching power supplies, converters, free-wheeling diodes, welding, and reverse battery protection.
