    Products Detail

    STFN42 Overview


    As dc = Ic/Ib, DC current gain is the ratio of base current to collector current, and DC current gain for this device is 10 @ 400mA 5V.The collector emitter saturation voltage is 1.5V, which allows for maximum design flexibility.When VCE saturation is 1.5V @ 250mA, 750mA, transistor means Ic has reached transistors maximum value (saturated).Emitter base voltages of 9V can achieve high levels of efficiency.Fuse current ratings refer to how much current the fuse can carry for an indefinite period without deteriorating too much, and this device has a current rating of 1A.This device can take an input voltage of 400V volts before it breaks down.A maximum collector current of 1A volts can be achieved.

    STFN42 Features


    the DC current gain for this device is 10 @ 400mA 5V
    a collector emitter saturation voltage of 1.5V
    the vce saturation(Max) is 1.5V @ 250mA, 750mA
    the emitter base voltage is kept at 9V
    the current rating of this device is 1A
