HIGH VOLTAGE POWER SCHOTTKY RECTIFIER
s
Negligible switching losses
s
Low forward voltage drop
s
Low capacitance
s
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.
