MOSPEC
Schottky Barrier Rectifiers
Using the Schottky Barrier principle with a Refractory metal capable of
high temperature operation metal. proprietary barrier technology allows for
reliable operation up to 150℃ junction temperature. Typical application are
in switching Mode Power Supplies such as adaptors, DC/DC converters
free-wheeling and polarity protection diodes.
