Working Principle

The KSA1203OTF is comprised of three main components – an emitter, a collector and a base. A semiconductor material is used to construct each of these components. The purpose of the transistor is to control the current flow between the emitter and the collector, using a current signal sent to the base.

The signal sent to the base determines the operation mode of the device. When the signal is low, the device is in a put-off mode. The device is then “turned off” and no current is passed through the device. When the signal is high, the device is in an off-on mode, which allows current to pass through. The current gain of the device and the resulting voltage gain is determined by the resistance of the collector and the current passed through it.

The KSA1203OTF can be used in a variety of circuits, such as amplifiers, audio devices, switch operations and motor controllers. Its low noise performance and high input impedance makes it an ideal choice for applications requiring these characteristics.
