What are the common semiconductor components?

PCB factory: semiconductor components, as the name suggests, its main materials are semiconductors, electronic technology is changing with each passing day, and new semiconductor components are emerging one after another. Semiconductor components have always been at the core of electronic components. Today, let us take a look at what are the common semiconductor components!

diode
British scientist Fleming invented the diode at the end of the 19th century and the beginning of the 20th century, and it was also the first to apply semiconductors to electronic components. Times have changed. In today's advanced technology, diodes are commonplace. Especially in various electronic circuits, the use of diodes and resistors, capacitors, inductors and other components to make reasonable connections to form circuits with different functions can achieve Various functions such as AC rectification, detection of modulation signals, amplitude limiting and clamping, and voltage stabilization of the power supply.

Bipolar transistor
Semiconductor transistors are composed of bipolar transistors and field effect transistors. However, the invention and application of the bipolar transistor is much earlier than the field effect transistor, so it is customary to refer to the bipolar transistor as a triode or transistor for short. Bipolar transistors are composed of two back-to-back PN structures. When they are in operation, they carry both electron and hole carriers, and both of them participate in conduction. Therefore, it is called "bipolar", which is used to distinguish One of the important reasons for a field-effect transistor with carrier conduction.

Insulated gate field effect transistor
We have just mentioned the field-effect transistor roughly, now let’s learn more about it. A field effect transistor is a semiconductor device that uses the intensity of an electric field generated by an external voltage to control its conductivity. According to its structure, it can be divided into two categories: junction field effect transistor and insulated gate field effect transistor. Insulated gate field effect transistors are divided into N-channel and P-channel according to their different conductivity types, and each type is further divided into two types: enhancement type and depletion type.

Semiconductor Optoelectronic Devices
The conversion between the two different energies of light and television is also reversible. Semiconductor devices can be used as media for the conversion of light and electric energy. The photons in the irradiated light can break the covalent bond of the semiconductor crystal and release electrons under the action of light; and the energy emitted by the recombination of electrons and holes can also be radiated in the form of light of a certain wavelength under the action of an electric field. Semiconductor electronic devices used for light, electrical energy or signal conversion use different materials and processes. We are all referred to as semiconductor optoelectronic devices manufactured by structure.

These are common semiconductor components. After reading this article, can you understand it?
