DESCRIPTION
The 403CNQ... 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.
