KSD1621UTF is a type of single bipolar transistor. It has three pins, the collector (C), the base (B) and the emitter (E). It is mainly used as a driver for small motors and as a control for circuits such as amplifiers, switches and relays.
Application Field of KSD1621UTF
- Power Circuits
- Amplifiers
- Switches and Relays
- Small Motors
- Converters
- Display Devices
Working Principle of KSD1621UTF
- When a voltage is applied to the base of the transistor, the filled electron shell of it increases. This results in the electrons in the base layer being drawn to the base region and hence, the conduction of current is increased.
- The collector collects the current from the base and it can be used for various applications such as amplifiers or small motor drivers.
- The collector-base junction is normally reverse biased, so that current does not flow from collector to base.
- The emitter of the transistor releases the electrons from the base and makes the current flow from collector to emitter.
- In the absence of a base current, the collector-emitter current will be zero.
