The 409DMQ Schottky rectifier doubler module series has
been optimized for low reverse leakage at high temperature.
The proprietary barrier technology allows for reliable operation
up to 175 °C junction temperature. Typical applications are in
high current switching power supplies, plating power supplies,
UPS systems, converters, free-wheeling diodes, welding, and
reverse battery protection.
