Established in year 2004, we are one of the promising suppliers of NPN Transistor. It is transistor in which a single p-type semiconductor layer is sandwiched between two n-type semiconductor layers. Our transistor has three terminals: emitter, collector, and base. It can work as either an amplifier or an electronic switch. When acting as an amplifier, a small base current is amplified to produce large collector and emitter current. NPN Transistor is faster than other types of transistors due to a fact that electron mobility is higher than hole mobility. Our transistor is used in mobile phones, speakers, and in almost every device where sound amplification is required.
