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”.

WebBJTs are also simply known as bipolar transistors. 8.1 INTRODUCTION TO THE BJT A 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 NPNBJT. (A PNPBJT would have a P+emitter, N-type base, and P-type collector.) NPN transistors exhibit higher transconductance and T WebThe three leads of a BJT are Collector, base and emitter. Two types of BJT are NPN and PNP. A Bipolar Junction transistor is a current controlled device. The amount of current flow between the collector and the emitter is determined by the base current.
