    Products Detail

    BULK128D-B Overview


    In this device, the DC current gain is 8 @ 2A 5V, which is calculated by taking the ratio of the base current to collector current and dividing transistor by two.Saturation of VCE means Ic is at its maximum value (saturated), and VCE saturation (Max) is 1.5V @ 500mA, 2.5A.Keeping the emitter base voltage at 9V allows for a high level of efficiency.Maximum collector currents can be below 4A volts.

    BULK128D-B Features


    the DC current gain for this device is 8 @ 2A 5V
    the vce saturation(Max) is 1.5V @ 500mA, 2.5A
    the emitter base voltage is kept at 9V


    BULK128D-B Applications
