It is also used in some circuit designs to increase voltage and current gain. Additionally, it is also used in telecommunication circuits and as a high speed switch.

Working Principle

Bipolar junction transistors (BJT) work on the principle of current amplification. The base-emitter junction, when forward-biased, allows the flow of current. This is then amplified through the base-collector junction. The collector current (Ic) is related to the base current (IB) by the gain current ratio or hFE. This factor determines the gain of the BJT.

The PBSS4021NT,215 has a myriad of features making it a great choice for many applications. With its low power dissipation and high gain, it is an excellent choice for many designs, including power switching and motor control.
