MPSA13 TO92 NPN Transistor

MPSA13 is an NPN darlington transistor manufactured in TO-92 package. It is a widely used transistor. It is a darlington transistor, which means it has two transistors or a pair of identical transistors connected in a special way called a darlington pair. It has a DC current gain of 5000, so the collector and emitter will be saturated with a very small amount of current, and the maximum collector-emitter saturation voltage is only 1.5V. The maximum collector current of the transistor is 500mA or 0.5A, which is quite enough to drive various loads. The maximum collector loss is 625 mW, so it can also be used as an amplifier and pre-amplifier for audio and other signals in electronics.
