What are the types of active electronic components?

25 March, 2025

What are the types of active electronic components? Electronic components can be categorized into two main types: active electronics components and passive electronics components. Among them, what kinds of active electronic components are included? We have taken a look at some of the more common active electronic components, and hope to bring you some reference.

Power Supplies

A power supply is a basic type of active electronic components that provides DC or AC power to a circuit to ensure that the circuit works properly. There are many types of active electronics components in the power supply category, including dry cell batteries, storage batteries, AC adapters, etc. They are used to provide stable operating voltage and current for circuits. Their role is to provide stable operating voltage and current for the circuit.

Transistor

Transistors are semiconductor electronic components that amplify current and are one of the more commonly used active electronic components in modern electronic circuits.

Transistors can be subdivided into three types: DIODES, triodes and tetrodes, which are suitable for different applications. Overall, transistors are active electronics components for current amplification, switching circuits, signal modulation and so on.

Field Effect Transistor

A field effect transistor is a semiconductor device that controls current through electric field effects and is therefore one of the active electronic components. Same as active electronic components, but field effect transistor and bipolar transistor are different, field effect transistor only majority carriers involved in the conductive, independent of the minority carriers. Therefore, it has the advantages of high input resistance, low noise, low power consumption, large dynamic range, easy to integrate, no secondary breakdown phenomenon, and a wide safe operating region.

Integrated Circuit

Integrated circuits are an important representative of active electronic components, which are miniature electronic devices that integrate multiple electronic components on a single silicon wafer, and have the advantages of small size, low power consumption, stable performance, and so on.

This kind of active electronics components is widely used in computers, cell phones, TVs and other electronic devices, mainly playing the role of signal processing, data storage, logic control and so on.

Operational Amplifiers

Operational amplifiers are high-performance integrated circuits, and are therefore one of the active electronics components. This kind of active electronics components has a great multiplier and input impedance, and is able to perform linear amplification, differential amplification, integration, differentiation and other operations on the input signal, which is widely used in the fields of analog signal processing, measurement and control, and communication.

Different active electronic components can achieve different functions, including the role of operational amplifiers, including signal amplification, differential amplification, signal processing and so on.In addition to these, there are many types of active electronic components, such as silicon controlled rectifiers. Different active electronics components can play different roles to provide support for the development of the electronics industry.
