WebThe BJT is a bipolar junction transistor whereas MOSFET is a metal oxide semiconductor field-effect transistor. A BJT has three terminals namely base, emitter, and collector, while a MOSFET has three terminals namely source, drain, and gate. BJT’s are used for low current applications, whereas MOSFET is used for high power applications. WebSep 8, 2024 · FIGURE 1. An NPN transistor looks like a pair of diodes back-to-back. The base-emitter diode is forward-biased while the base-collector diode is reverse biased. Note that the collector current does not flow to the emitter through the reverse-biased base-collector diode. Instead, it flows direct to the emitter via “transistor action”.
