Transistor Product classification

Transistor Product classification

Divided into two types based on polarity: one is the NPN type transistor, which is the most commonly used type, and the other is the PNP type transistor.

There are two types of materials: one is silicon transistor, which is the most commonly used one, and the other is germanium transistor, which was previously used more frequently.

Three electrodes are divided into two types according to their operating frequency: one is a low-frequency transistor, mainly used in areas with relatively low operating frequencies; Another type is high-frequency transistor, mainly used in areas with high operating frequencies.

There are three types of transistors based on power: one is a low-power transistor, which has a lower output power; One type is a medium power transistor, which has a higher output power; Another type is high-power transistor, which can have a large output power and is mainly used in high-power output situations.
