  • Single Schottky rectifier suited to Switched Mode Power Supplies and high frequency DC to DC converters, freewheel diode and integrated circuit latch up protection.

    Packaged in SMA and SMB, this device is especially intended for use in parallel with MOSFETs in synchronous rectification.

    Key Features

    • Very low forward voltage drop for less power dissipation
    • Surface mount miniature packages
    • Optimized conduction/reverse losses trade-off which means the highest yield in the applications
    • Avalanche capability specified
