    Products Detail

    The STA421A is a PNP general purpose transistor designed for high-current applications. It features a collector current of -3A continuous and -6A pulse, with a collector-emitter voltage of -60V. The device offers fast switching times (ton=0.25µs, tstg=0.75µs, tf=0.25µs) and low saturation voltage (VCE(sat)=-1.0V max). It operates over a wide temperature range from -40°C to +150°C and is suitable for various amplification and switching circuits.

    Key Features

    • High current capability: -3A continuous, -6A pulse
    • High voltage rating: -60V
    • Fast switching times: ton=0.25µs, tstg=0.75µs, tf=0.25µs
    • Low saturation voltage: -1.0V max
    • Wide operating temperature: -40°C to +150°C
    • Minimum hFE of 40 at -1A
