HIGH VOLTAGE POWER SCHOTTKY RECTIFIER
■Negligible switching losses
■Low forward voltage drop
■Low capacitance
■High reverse avalanche surge capability
FEATURES
High voltage dual Schottky rectifier suited for
switchmode power supplies and other power
converters. Packaged in TO-220AB, this device
is intended for use in medium voltage operation,
and particularly, in high frequency circuitries
where low switching losses and low noise are
required.
