Description/ Features
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 擄C junction temperature.
Typical applications are in switching power supplies, convert-
ers, free-wheeling diodes, welding, and reverse battery
protection.
