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. WebA diode is a device with two conductors. If you break emitter conductor of a bipolar transistor, then you’ll obtain a “collector–base diode”, but lose a transistor. While it is still a transistor, the thing is called the C–B junction …

BJTs exist as PNP and NPN types, based on the doping types of the three main terminal regions. An NPN transistor comprises two semiconductor junctions that share a thin p-doped region, and a PNP transistor comprises two semiconductor junctions that share a thin n-doped region.
