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 bipolar junction transistor has 3 regions: the base, the collector, and the emitter. This is illustrated below: The collector region is the region of the transistor where the amplified current is output from. It is the output region through where the amplified current leaves through a transistor. Role of Collector Region of a BJT Transistor
