    Products Detail

    BD438 Overview


    In this device, the DC current gain is 30 @ 10mA 5V, which is calculated by taking the ratio of the base current to collector current and dividing transistor by two.A collector emitter saturation voltage of 200mV ensures maximum design flexibility.Saturation of VCE means Ic is at its maximum value (saturated), and VCE saturation (Max) is 600mV @ 200mA, 2A.Keeping the emitter base voltage at 5V allows for a high level of efficiency.3MHz is present in the transition frequency.An input voltage of 45V volts is the breakdown voltage.Maximum collector currents can be below 4A volts.

    BD438 Features


    the DC current gain for this device is 30 @ 10mA 5V
