Introduction of transistor and thyristor
A transistor is a type of triode that consists of an emitter, a base, and a collector. Its main role is to amplify electrical signals and control currents. The transistor works by controlling the collector current by controlling the base current, thereby realizing functions such as current amplification and switching control. Transistors are commonly used in circuits such as amplifiers, switches, oscillators, etc. in electronic circuits. Transistors are mainly divided into bipolar transistors (BJT) and field effect transistors (FET).
A thyristor is a triac that controls the on/off and direction of current. The working principle of thyristor is to control the main electrode current by controlling the gate current, so as to realize functions such as current control and voltage regulation. Thyristors are commonly used in circuits such as voltage regulation, current control, and DC power conversion in AC circuits.
Therefore, transistors and thyristors are both semiconductor devices, but their working principles and application scenarios are different, and it is necessary to choose which device to use according to the specific circuit design and requirements.

Small size: The transistor is small in size and light in weight, making it easy to integrate and assemble.
Characteristics of thyristor
Strong controllability: The thyristor can control the main current by controlling the gate current to achieve current control and regulation.
Bidirectional conduction: The thyristor can conduct current in both directions and can control and regulate forward and reverse currents.
High reliability: The thyristor has a long life, high reliability, not easy to be damaged, and has a long service life.
Small size: The thyristor is small in size and light in weight, making it easy to integrate and assemble.
Therefore, both transistors and thyristors have the advantages of high reliability and small size, but they are different in functions and application scenarios. The choice of which device to use needs to be based on the specific circuit design and requirements.
