Triode, the full name should be semiconductor triode, also known as bipolar transistor, crystal triode, is a semiconductor device that controls the current. Its function is to amplify the weak signal into a larger amplitude value of the electrical signal, also used as a non-contact switch.
Triode is one of the basic components of semiconductor, which has the role of current amplification and is the core component of electronic circuits. Triode is made on a semiconductor substrate two close to each other PN junction, two PN junction to the whole semiconductor is divided into three parts, the middle part is the base area, the two sides of the part is the emission area and the collector area, PNP and NPN arrangement.
