WebWhat is BJT – Bipolar Junction Transistor? Bipolar junction transistor (BJT) is a bidirectional device that uses both electrons and holes as charge carriers. While Unipolar transistor i.e. field effect transistor uses only one type of charge carrier.BJT is a current controlled device. The current flows from emitter to collector or from collector to emitter …
