  • Dual center tap Schottky barrier rectifier designed for high frequency switched mode power supplies and DC to DC converters.

    Packaged in TO-220AB, TO-247 and D2PAK these devices are intended for use in low voltage,
    high frequency inverters, free-wheeling and polarity protection applications.

    Key Features

    • Low forward voltage drop meaning very small conduction losses
    • Low switching losses allowing high frequency operation
    • Avalanche capability specified
