Multiple-emitter transistor

A multiple-emitter transistor is a type of transistor that has more than one emitter terminal. This design allows it to be used in applications where multiple signals need to be amplified simultaneously or where multiple input sources can be connected to the same transistor. Despite its name, the multiple-emitter transistor is typically just a variation of a standard bipolar junction transistor (BJT) or field-effect transistor (FET).
