2SC4081U3T106R

2SC4081U3T106R is a NPN epitaxial planar silicon transistor and can be classified under Transistors - Bipolar (BJT) - Single.

The application fields of 2SC4081U3T106R transistors include output applications such as sensing, drive and astable multivibrator circuits, motor control, power switching circuits and other low frequency switching applications. Its maximum collector current rating is 0.5A and maximum voltage rating is 50V.

The working principle of a transistor involves three connections: the base, collector, and emitter. The base controls the entire circuit, by controlling the current flowing from collector (input) to the emitter (output). The current is regulated by the current amplification factor, or β. If the current flowing from the collector to the emitter increases, the current through the collector also increases, and therefore the current flowing to the emitter will increase too.

When voltage is applied to the base terminal, current begins to flow from the collector to the emitter; this current is known as the input or collector current. The base current is then amplified and sent through the base-collector junction. This amplified current is then sent back to the emitter as the output, or emitter current. This action then causes the collector current, and thus the input current, to increase. This current increase is proportional to the gain of the transistor.

The collector in a 2SC4081U3T106R transistor acts as the input terminal, and the emitter acts as the output terminal. The base terminals receive the bias voltage that is used to control the current gain of the transistor, and so it is important to ensure that the correct voltage is applied to the base to obtain the desired gain.

In summary, a 2SC4081U3T106R is an NPN epitaxial planar silicon transistor that is used in switching applications, motor control and other low frequency switching applications. It has a maximum collector current rating of 0.5A and maximum voltage rating of 50V, and uses the base terminal to control the current flowing from the collector to the emitter, which is proportional to the current gain of the transistor.
