  • Thanks to highly sensitive triggering levels, the 0.25 A P0109AL SCR Thyristor is suitable for all applications where available gate current is limited. Its high immunity makes it ideal for high electric noise circuits.

    The surface mount SOT23-3L package allows compact SMD based designs for automated manufacturing.

    Key Features

    • IT(RMS) 0.25 A
    • Low 1 µA gate current
    • High noise immunity 100 V/µs
    • ECOPACK®2 compliant component
