2pcs c945 transistor

C945 is an NPN bipolar junction transistor. It is composed of three regions: emitter, collector, and base. The base is doped with P semi-conductor type material. The collector and emitter are both coated with N-type semiconducting material. It’s a low-cost gadget and is extremely popular on the market because of its wide array of applications. Its functions include fast switching amplifying, low-power electronic circuits, and many more.
