  • ​Dual center tap fast recovery epitaxial diodes suited for switch mode power supply and high frequency DC to DC converters.

    Packaged either in TO-220AB and D2PAK, this device is particularly intended for secondary rectification inside SMPS with high space and power density.

    Key Features

    • Ultrafast, soft and noise-free recovery
    • Low forward voltage drop meaning very small conduction losses
    • ECOPACK®2 compliant component for D²PAK on demand
