2N5822 is a small-signal PNP bipolar junction transistor (BJT). It has a maximum collector current of 200mA and can handle collector-emitter voltages up to 40V. It is widely used in general-purpose amplifier and switching applications.

A bipolar junction transistor consists of three layers of semiconductor. The base layer acts as a control electrode, the emitter is the electron source and the collector is the electron sink. When a positive voltage is applied to the base, the electrons from the emitter are attracted to the base. This causes the current to start flowing, and the transistor is said to be in the “on” state. When the voltage is removed, the transistor is said to be in the “off” state. This is the basic working principle of a BJT.

2N5822 is a versatile transistor and can be used for a variety of applications, including:

• Amplifiers: 2N5822 can be used as an amplifier in audio and RF applications. It can provide gain up to 200 and can handle power outputs up to 2.5W.
