The working principle of the 2N4402TA consists of two distinct electrodes, the base and the collector connected to the central terminal. The base is connected to the source and delivers a current that flows from the collector to the emitter. This current is dependent on the voltage difference between the base and the emitter, and the size of the base-collector junction. This current flow is controlled by the base current which is supplied by the emitter and serves as the input voltage. The collector-emitter voltage is regulated by adjusting the voltage difference between the base and emitter, producing a flow of electrons or holes in the emitter. This movement produces a continuous current in the collector circuit, this current is regulated by controlling the base current.

The 2N4402TA is a small signal, general-purpose transistor designed for use in a variety of medium-power applications. Its wide range of features makes it ideal for use in consumer, automotive and industrial applications. It has a low collector-emitter saturation voltage and a fast switching speed, making it suitable for low-voltage, high-frequency applications.
