For the patch transistor, some people in the industry call it a semiconductor transistor. The semiconductor transistor has a current amplification effect. It is divided into two types: bipolar and unipolar.

Bipolar semiconductor transistors are also called crystal transistors, or triodes for short. It is named because of the electric field and electron carriers involved in conduction during work.

The unipolar semiconductor transistor is also called a field effect transistor. It is a semiconductor transistor that uses the electric field effect to control the output current. Only one type of carrier (majority carrier) participates in conduction during operation, so it is called a unipolar semiconductor transistor.

The transistor has three poles, three regions, and two PN junctions. According to the power, it can be divided into: small power tube <500mW, medium power tube 0.5~1W, high power tube> 1W
