The Working Principle

A transistor is a semiconductor device whose main function is to amplify electronic signals. It works using an electrically operated switch which opens and closes depending on the current applied, allowing the electronic signals to pass through it. In the case of a bipolar junction transistor (BJT), this is done by an electric current passing through two “base” terminals of the transistor, forming the transistor’s “collector” and “emitter”. The size of the current passing through the BJT’s base is directly proportional to the current passing through the collector and emitter, allowing for amplification of the input signal.

The 2SC4793, YHFJ (J) utilizes this principle to function as a low power amplifier. When a signal is fed into the base, the electric current passing through the collector and emitter of the transistor depending on the size of the input signal. This electric current is then amplified and passes through the output. Thus, with the help of the transistor, small input signals can be amplified and transferred to the output.
