ON transistor price, we Beijing transit Askey Electronics Co., Ltd. is a professional switching power supply, power inverter, power inverter, communications power, automotive power, servo motors, motor controllers, industrial equipment and other services to provide a full range of the transistor, the full name shall semiconductor transistor, also known as bipolar transistors, a transistor, a current controlled semiconductor device. Its role is to weak signal amplified electrical signal into amplitude value is larger, also used as a non-contact switch. As the main component, it promptly, generally the first to be applied in the communications tools and produce huge economic benefits. In the manufacture of transistors, consciously make the majority of the emitter region of the carrier concentration is greater than the base region, while very thin base region, and to strictly control the content of impurities, so that once the power is turned on, due to the emitter junction is forward biased , majority carriers (holes) emitting region majority carriers (electrons) and the base region is very easily across the emitter diffusion on each other, but the concentration of the base of the former than the latter, so that the current through the emitter basically a flow of electrons, which shares the electron emitter current of a stream called. Transistor, is one of the basic components of a semiconductor, having current amplification effects, is the core element of an electronic circuit. Transistor promote and brought "solid revolution", thus promoting the semiconductor electronics industry worldwide. Due to the structure of the transistor revolutionized electronic circuits, integrated circuits and LSI have emerged, such as the manufacture of high-precision equipment like high-speed computer becomes a reality.
