  • The 2STF1550 and 2STN1550 are NPN transistors manufactured using new \"PB-HCD\" (Power bipolar high current density) technology.

    The resulting transistor shows exceptional high gain performances coupled with very low saturation voltage.

    Key Features

    • Very low collector-emitter saturation voltage
    • Fast switching speed
    • High current gain characteristic
    • Surface mounting devices in medium power SOT-89 and SOT-223 packages
