What is the use of semiconductor discharge tube? Semiconductor discharge tube manufacturers say

Semiconductor discharge tube manufacturers say that in the protection device, it is characterized by large current, slow response time and high impulse breakdown voltage. TVS diode has small flux, fast response time and good voltage clamping characteristics. The characteristics of the varistor are between the two; the semiconductor discharge tube conduction and breakdown voltage is accurate, the reaction speed is fast, less than 1ns. When a protection circuit requires a large total current and can achieve fine protection, the protection circuit often needs the cooperation of these protection devices to achieve the ideal protection characteristics.

How is the selection of semiconductor discharge tube?

How is the selection of semiconductor discharge tube?

Semiconductor discharge tube is a common overvoltage maintenance device in modern communication equipment, which can prevent communication equipment from being damaged by lightning and surge. At present, the wires in the wired communication network are metal wires and optical fibers. The wires are installed outdoors and will inevitably be affected and destroyed by nature and man-made.

What are the selection criteria for solid state relays?

What are the selection criteria for solid state relays?

When selecting solid state relays for small current specification printed circuit boards, because the lead terminals are made of high thermal conductivity materials, welding should be stopped under the conditions of temperature less than 250 ℃ and time less than 10S. If you think about the reason for the surrounding temperature, you can think about derating application if necessary, and generally control the load current within 1/3 of the rated value. When the charged load is turned on, a large surge current will be generated. Because the heat is too late to distribute, it is likely to damage the SCR inside the SSR. Therefore, the user should analyze the surge characteristics of the charged load when selecting the relay, and then select the relay. The relay can accept this surge current under the premise of ensuring steady-state operation. When selecting, refer to Table 2 for derating coefficients of various loads (at normal temperature).
