    Products Detail

    BULK128 Overview


    The DC current gain is the ratio of the base current to the collector current ?dc = Ic/Ib and the DC current gain for this device is 14 @ 2A 5V.Vce saturation means Ic is at its maximum value(saturated), and the vce saturation(Max) is 500mV @ 1A, 4A.If the emitter base voltage is kept at 9V, a high level of efficiency can be achieved.Collector current can be as low as 4A volts at its maximum.

    BULK128 Features


    the DC current gain for this device is 14 @ 2A 5V
    the vce saturation(Max) is 500mV @ 1A, 4A
    the emitter base voltage is kept at 9V
