DESCRIPTION
Dual center tap Schottky rectifier suited for
SwitchMode Power Supply and high frequency
DC to DC converters.
Packaged either in TO-220AB, TO-220FPAB,
I2PAK, or D2PAK, this device is especially
intended for use in low voltage, high frequency
inverters, free wheeling and polarity protection
applications.
