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”. WebA BJT is made of a heavily doped emitter (see Fig. 8–1a), a P-type base, and an N-type collector. This device is an NPN BJT. (A PNP BJT would have a P+ emitter, N-type base, and P-type collector.)

WebThus, the BJT transistor consists of two pn junctions, connected back-to-back. These are called the emitter-base junction (EBJ) and the collector-base junction (CBJ). The circuit symbols for both kinds of BITs are shown in Figure 1. BJTs are asymmetrical devices, i.e. the collector and emitter regions are dissimilar.

WebDoes current flow from collector to emitter or from emitter to collector? And the answer depends on the type of transistor in use.
