2N2222 transistor

Description

The 2N2222 transistor is used to amplify or switch small signals.

This transistor consists of three pins called emitter, base, and collector.
The emitter acts as a source of current, and the collector serves to accept the current. The base accepts control signals and regulates the flow of current.

The 2N2222 transistor accepts a small current input signal, amplifies it, and outputs a large current. Mainly used in amplifiers, switching circuits, etc.

They are designed for high-speed switching applications at collector currents up to 500 mA, and feature useful current gain over a wide range of collector current, low leakage currents and low saturation voltages.
