Why heat dissipation for triode?

1 Triode is a large-scale integrated circuits are very important electronic components, triode as a semiconductor device, its own heat dissipation is not obvious, so, from time to time need to add a heat sink on its collector. Because the higher the current, the higher the temperature is too high will make the triode load capacity decline, the speed of the output voltage and current will also fall within a certain range, to a certain extent will burn the device. Such as working in the switching state of the transistor temperature is too high will make its frequency characteristics decline that conduction in high-power circuits, heat dissipation of this link is very important.

2 triode, full name should be semiconductor transistor, also known as bipolar transistor, crystal transistor, is a current control current semiconductor devices - its role is to amplify the weak signal into a larger amplitude value of the electrical signal, but also used as a contactless switch. Crystalline transistor, is one of the basic semiconductor components, with the role of current amplification, is the core component of electronic circuits. Triode is a semiconductor substrate on the production of two very close to each other PN junction, the two PN junction of the entire semiconductor into three parts, the middle part of the base area, the two sides of the part of the emitting area and the collector area, the arrangement of PNP and NPN two kinds.
