  • Single Schottky rectifier suited for high frequency Switch Mode Power Supply.

    Packaged in TO-220AC, this device is intended to be used in notebook & LCD adaptors, desktop SMPS, providing in these applications a margin between the remaining voltages applied on the diode and the voltage capability of the diode.

    Key Features

    • High junction temperature capability
    • Low leakage current
    • Avalanche rated
    • Good trade-off between leakage current and forward voltage drop
