  • The STPS1170 is a 170 V Schottky rectifier suited for switch mode power supplies and high frequency DC to DC converters.

    Packaged in SMA Flat and SMA Flat Notch, the STPS1170 is ideal for use in low voltage, high frequency inverters, freewheeling and polarity protection. Also ideal for all LED lighting applications where efficiency and space constraint are required.

    Key Features

    • Negligible switching losses
    • High junction temperature capability
    • Very small conduction losses
    • Low leakage current
    • Avalanche rated
    • ECOPACK2 component
