  • This 150 V power Schottky rectifier is ideal for switch mode power supplies on up to 24 V rails and high frequency converters.

    Packaged in SMA and axial, the STPS1150 is optimized for use in consumer and computer applications where low drop forward voltage is required to reduce power dissipation.

    Key Features

    • Negligible switching losses
    • Low forward voltage drop for higher efficiency and extended battery life
    • Low thermal resistance
    • Surface mount miniature package
    • Avalanche capability
    • ECOPACK®2 compliant component
