    Products Detail

    ST631K Overview


    This device has a DC current gain of 120 @ 100mA 5V, which is the ratio between the base current and the collector current.A VCE saturation (Max) of 500mV @ 50mA, 500mA means Ic has reached its maximum value(saturated).A high level of efficiency can be achieved if the base voltage of the emitter remains at 5V.A maximum collector current of 1A volts is possible.

    ST631K Features


    the DC current gain for this device is 120 @ 100mA 5V
    the vce saturation(Max) is 500mV @ 50mA, 500mA
    the emitter base voltage is kept at 5V
