The transistor, as the core component in the electronic circuit, plays an important role in amplifying the current and controlling the current and voltage. S9014 is a common silicon NPN transistor, which occupies an important position in electronic engineering due to its good electrical properties and wide range of applications.
The basic structure of the transistor is composed of three electrodes: collector, base and emitter, and the working principle of S9014 as an NPN type transistor mainly depends on the flow of electrons. When a small voltage is applied to the base, the electrons in the base are excited and flow towards the collector, forming a collector current. At the same time, holes in the collector flow to the emitter, forming an emitter current. The interaction of these two currents makes the transistor have the function of amplifying the signal.
