The triode is one of the basic semiconductor components. It has the function of current amplification and is the core component of electronic circuits. The triode is made of two PN junctions very close to each other on a semiconductor substrate. The two PN junctions divide the positive semiconductor into three parts. The middle part is the base area, and the two sides are the emitter area and the collector area. The arrangement is PNP And NPN, two kinds. The main purpose of S9012NPN triode: as audio amplifier and 1W push-pull output of radio.
