Working Principle

The NPN transistor consists of three terminals, namely a base, an emitter, and a collector. It is used for amplifying or switching electronic signals. Due to its higher gain, NPN transistors are used in switching applications. When a small current arrives at the base terminal, it is then amplified at the collector terminal.

The sequence of events taking place inside an NPN transistor is that the base current causes the base-emitter junction to turn on, which, in turn, causes the large current to start flowing from the collector to the emitter. This large current flow is stabilized by the current gain of the NPN transistor. This gain is expressed by the current gain factor hFE, which represents the amplification of the current between the collector and the emitter.

The KSB810YTA has high hFE linearity and high current gain which makes it very effective in audio amplification, DC motor control, and other switching applications. Moreover, it has a low noise profile, low distortion, and low saturation voltage.
