WebNPN Transistor. The NPN transistor consists of two n-type semiconductors that sandwich a p-type semiconductor. Here, electrons are the majority charge carriers, while holes are the minority charge carriers. The NPN transistor is represented, as shown below. In the above figure, we can see an arrow pointing outwards from the emitter terminal. Web2 de jan. de 2024 · NPN Transistors are three-terminal, three-layer devices that can function as either amplifiers or electronic switches. In the previous tutorial we saw that the standard Bipolar Transistor or BJT, comes in two basic forms. An NPN ( N egative- P ositive- N egative) configuration and a PNP ( P ositive- N egative- P ositive) configuration.
