WebApr 9, 2016 · The transistor is in reverse active mode. The collector acts as the emitter and the emitter as the collector. This is possible because NPN reversed is still NPN. The performance is worse than in forward active mode, because emitter and collector usually have different doping levels and a different structure. The transistor operates as switched ON in saturation mode and switched OFF in cut-off mode. When both junctions are connected in the forward bias condition and sufficient voltage is given to input voltage. In this condition, collector-emitter voltage is near to zero and the transistor operates as a short circuit. In … See more An NPN transistor is the most commonly used bipolar junction transistor, and is constructed by sandwiching a P-type semiconductor … See more As discussed above, the NPN transistor has two junctions and three terminals.
