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”. The BJT remains a device that excels in some applications, such as discrete circuit design, due to the very wide selection of BJT types available, and because of its high transconductance and output resistance compared to MOSFETs. The BJT is also the choice for demanding analog circuits, especially for very-high-frequency applications, such as radio-frequency circuits for wireless systems.
