Electronic components refer to the collective term for electronic components and semiconductor power devices used in electronic circuits,
It is a fundamental element in electronic circuits,
Used to achieve specific electrical characteristics or functions.
Among them, electronic components refer to finished products that do not change their molecular composition during factory production and processing,
Such as resistors, capacitors, inductors, etc.
Because it does not produce electrons itself, it has no control or transformation effect on voltage and current,
So it is also known as a passive device;
Electronic devices refer to finished products that have changed their molecular structure during factory production and processing,
For example, transistors, electronic tubes, integrated circuits, vertical devices, chips, etc. Because it can generate electrons itself,
Has control and transformation effects on voltage and current (amplification, switching, rectification, detection, oscillation, modulation, etc.),
So it is also known as an active device.
Semiconductor components are an indispensable component of electronic devices, widely used in fields such as communication, computers, consumer electronics, and automotive electronics. The main categories or types of semiconductor components include:
1. Rectifier device: including diodes and rectifier bridges, used to convert alternating current into direct current, commonly used in power circuits.
2. Amplification devices: including transistors and field-effect transistors, used to amplify electrical signals, commonly used in amplifiers, audio equipment, etc.
3. Switching devices: including thyristors, thyristors, etc., used to control the on/off of current, commonly used in power switches, dimmers, etc.
4. Sensor components: including temperature sensors, pressure sensors, photoelectric sensors, etc., used to sense environmental signals and convert them into electrical signals.
5. Logic devices: including AND gates, OR gates, NOT gates, etc., used to implement logical operations, commonly used in digital circuits, computers, etc.
6. Storage devices: including random access memory (RAM), read-only memory (ROM), etc., used to store data and programs.
7. Integrated Circuit (IC): Integrating multiple semiconductor devices onto a single chip, commonly used in various electronic devices.
8. Optoelectronic devices: including photodiodes, phototransistors, etc., used for photoelectric conversion and optical signal detection.
9. Transmission devices: including fiber optic transceivers, drivers, etc., used for fiber optic communication and data transmission.
10. Power devices: including power diodes, power transistors, etc., used for high-power circuits and power control.
