In the process of using the solid-state relay, it is still good to check all aspects. After a period of heating, when I check it again, I find that the solid-state relay is broken. What is the reason for this? It is mainly the effect of temperature. What are the effects of temperature on the use of solid state relays?

1. In fact, solid-state relays are very sensitive to temperature. High and low temperatures may have a bad influence on it. When solid-state relays are operated in a high-temperature environment for a long time, they will cause rapid aging of their components. For example, internal plastics and insulating materials also have problems such as deterioration of parameters, difficulty in extinguishing arcs, and electrical oxidation. Faced with these various problems, solid-state relays should be operated with good heat dissipation and ventilation. Properly take some overheating maintenance on the solid state relay to avoid the above problems.

2. There are some problems with the operation of solid-state relays in high temperatures, but operating in low-temperature environments also requires the applicable range of temperature. If the temperature is too low, the same will also have a series of adverse effects on the solid state relay. For example, the cold sticking effect of the contacts will increase. We must fully consider the remaining temperature of the solid state relay, and try to control the influence of temperature on it within a small range.
