Working Principle of 2N4124TFR

2N4124TFR transistor is constructed of a P-type base material, a N-type emitter region and an N-type collector region. When a breakdown voltage is applied to the base-emitter junction of the device, current from the collector region passes through the base-emitter junction and is transferred to the emitter. This collector-emitter current will then cause a change in the potential of the collector region.The device works in such a way that when an input signal is applied to the base of the 2N4124TFR transistor, the resulting current will increase or decrease the N-type collector region. This causes a corresponding change in the voltage across the base-emitter junction, resulting in an output signal.
