Bipolar Junction Transistor (BJT) Basics CircuitBread

WebzA BJT is physically just two back to back PN diodes, with three contacts, but the current between the emitter and the collector is a minority carrier current in the base. zEssentially, a forward biased diode is used to create a minority current, most of which then goes all the way across to the depletion region of another, reverse biased diode. WebThe emitter efficiency is known as α = I C /I E. Types of BJT Bipolar junction transistors are available as PNP as well as NPN devices. We present a comparison of these two in Figure below. The difference is the polarity of the base emitter diode junctions, as signified by the direction of the schematic symbol emitter arrow. talking point ican
