Active electronic components are those that can amplify or generate electrical signals. They are the opposite of passive electronic components, which simply pass signals along. Some common examples of active electronic components include:

  • Transistors: Transistors are semiconductor devices that can amplify or switch electrical signals. They are the basic building blocks of many electronic circuits.

  • Diodes: Diodes are semiconductor devices that allow current to flow in one direction only. They are used in a variety of applications, such as rectifiers, filters, and oscillators.

  • Integrated circuits (ICs): ICs are miniaturized electronic circuits that are made up of many transistors and other components. They are used in a wide variety of electronic devices, such as computers, smartphones, and TVs.

  • Optoelectronic devices: Optoelectronic devices convert light into electricity or vice versa. They are used in a variety of applications, such as lasers, sensors, and displays.

  • Microcontrollers: Microcontrollers are small, programmable computers that are used in a variety of electronic devices. They can be used to control the operation of devices, such as motors, sensors, and displays.


Active electronic components are essential for the operation of many electronic devices. They are used to amplify, generate, and control electrical signals. By understanding how active electronic components work, you can better understand how electronic devices work.

Here are some of the materials used to make active electronic components:

  • Semiconductors: Semiconductors are materials that have electrical properties that are intermediate between conductors and insulators. They are used to make transistors, diodes, and other active electronic components.

  • Metals: Metals are used to make conductors, which are components that allow electricity to flow freely.

  • Inorganic compounds: Inorganic compounds are used to make insulators, which are components that prevent electricity from flowing.

  • Organic compounds: Organic compounds are used to make polymers, which are used to make the packaging for electronic components.


The materials used to make active electronic components are constantly evolving as new technologies are developed. By understanding the materials used to make active electronic components, you can better understand the limitations and potential of these components.
