DESCRIPTION
The 303CNQ... center tap Schottky rectifier 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,
freewheeling diodes, welding, and reverse battery
protection.
