As an amplifier, the 2SB1218ARL can be used to amplify small signal from input to a higher level of voltage at the output. For example, in an audio amplifier, an AC voltage signal is fed into the 2SB1218ARL transistor for the purpose of increasing the gain on the signal through the transistor. The transistor then amplifies the signal and outputs it to the speaker.

The working principle behind the 2SB1218ARL is BJT. A BJT is a kind of three terminal devices, which are current-controlled current devices. The basic principle of BJT is that they are able to amplify small electrical current signals and convert them into higher level amplified AC signals with the help of a small base current.

The base-emitter junction is a critical factor of BJTs; it acts as a voltage dependent switch which is controlled by the small base current. The forward-biased base-emitter junction will allow current flow to the collector. With an increase of small currents in the base connections, the base-emitter junction will become more forward bias, and more current will be allowed to flow from base to collector. The base-collector reverse bias junction will block the flow of current in the collector and hence, the voltage is amplified from the collector.

The 2SB1218ARL has a low saturation voltage of 0.65V and can be used for various signal processing purposes. The transistor is versatile and can= be used for various geometries or signal processing applications. It can be used for the amplifier, for signal regeneration and for signal conversion.
