Basic principles of surface mount diodes

Although surface mount diodes are not common electrical devices, they are the most commonly used electrical devices in our daily lives. So what is the basic principle of surface mount diodes?

The resistivity of surface mount diodes at room temperature is approximately between 10E-5 and 10E7 ohms per meter, and the resistivity index decreases as the temperature increases. Germanium and silicon are the most commonly used element surface mount diodes; Compound surface mount diodes include III-V compounds

Gallium arsenide, gallium phosphide, etc., II-VI compounds (cadmium sulfide, zinc sulfide, etc.), oxides (manganese, chromium, iron, copper oxides), and solid solutions composed of III-V and II-VI compounds (gallium aluminum arsenic, gallium arsenide phosphorus, etc.)

Etc.). In addition to the crystalline surface mount diodes mentioned above, there are also amorphous glass surface mount diodes, organic surface mount diodes, etc.

Therefore, it can be known that the conductivity of surface mount diodes is temperature dependent. The sensitivity of the material properties of surface mount diodes to temperature can be used to produce thermal and photosensitive devices, which is also the reason for the poor temperature stability of surface mount diode devices.

Through the analysis of these principles, one can also find the maintenance and upkeep of surface mount diodes in daily life. Remember, do not neglect the maintenance and upkeep of him just because of small relaxation, and do not let small things go to waste.
