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