What is a Darlington Transistor?

A Darlington transistor, also known as a Darlington pair, consists of a pair of bipolar transistors that are connected in order to provide a very high-current gain from a low-base current. In a Darlington transistor, the input transistor’s emitter is wired to the output transistor’s base and their collectors are tied together. Therefore, the current that is amplified by the input transistor is amplified even further by the output transistor.
