WebMar 15, 2024 · What is a NPN Transistor. An NPN transistor is the most commonly used bipolar junction transistor, and is constructed by sandwiching a P-type semiconductor between two N-type semiconductors. An NPN transistor has three terminals– a collector, emitter and base. The NPN transistor behaves like two PN junctions diodes connected … WebBJT. for short. Transistors are three terminal active devices made from different semiconductor materials that can act as either an insulator or a conductor by the …

The npn BJT and the pnp BJT. The BJT symbols and their corresponding block diagrams are shown on Figure 1. The BJT is fabricated with three separately doped regions. The npn device has one p region between two n regions and the pnp device has one n region between two p regions.
WebJan 7, 2016 · Storage time (ts) - how long to get out of saturation. Using the datasheet (these parameters are usually listed), you can figure out how fast a transistor can switch between the two states. f m a x = 1 t d + t r + t f + t s. * This is what transistor can theoretically do, but there are tricks that can be done to improve the switching speed.
