Classification of semiconductor discrete devices

Semiconductor discrete devices can be classified by their material, structure, or function. Among them, classification by function is a commonly used method, which is mainly divided into the following categories: 1. Diode: Also known as "diode tube", it is the simplest semiconductor device. It can conduct current under forward voltage, but cannot conduct current under reverse voltage. 2. Transistor: Also known as "transistor tube", it is a device that can amplify current and voltage and is used in medium and high-frequency amplification circuits such as television and radio. 3. Field effect transistor: also known as "transistor tube", it is a voltage-controlled current source, often used in signal amplification and switching circuits of high-frequency circuits. 4. Relay: It is a device that can control current on and off. It can drive large current switching actions at low voltage. It is often used in automation equipment and control circuits.
