Darlington

nounShop talkElectronics

A clipped name for a two-transistor configuration that provides very high current gain.

A shorthand reference to a Darlington pair, a compound structure consisting of two bipolar junction transistors. The emitter of the first transistor feeds directly into the base of the second, multiplying their individual current gains together. Engineers often use the single word when referring to pre-packaged integrated circuits that contain this arrangement.

Heard on the job

Swap out that standard NPN for a Darlington if you want to drive the relay directly from the logic pin.
