The STM MJD127T4 is a high-gain PNP bipolar Darlington transistor housed in a DPAK surface-mount package. It features a collector-emitter voltage of up to -100V and a continuous collector current of -8A, making it suitable for medium-power switching and amplification tasks. Its Darlington configuration combines two transistors in one package to offer a very high current gain, significantly reducing the base current required to drive it. This makes the MJD127T4 a reliable component in scenarios where efficient control and high current handling are necessary, particularly in saturated switching and linear applications.
