Gas Discharge Tube Arresters (GDT) are widely used in many industry applications due to their capability to protect electrical equipment from damage caused by external and internal overvoltage events. GDTs are able to absorb overvoltage, dissipate it as heat, provide isolation between two conductors, and protect against high surges which could damage sensitive equipment. Among the various types of GDTs, the VIS800 series from Vishay Intertechnology is one of the most reliable and efficient GDTs currently available on the market.

The VIS800 series is especially designed for high power applications, as its design holds significantly higher surge capability compared to traditional GDTs. These GDTs are entirely constructed from non-hygroscopic materials, providing exceptional performance in environments with higher levels of moisture and humidity, such as construction and industrial sites where the air-conditioning could be compromised. In addition, the design of the VIS800 series helps it to be immune to corrosion, making it able to adequately protect circuit elements in even the most corrosive environments.

The working principle of the VIS800 series is based on a silicon dioxide (silica) gas discharge tube, which works by allowing current to flow through the device when there is an overvoltage event. When the overvoltage exceeds the GDT\'s threshold, the gas discharge tube conducts current and dissipates the voltage as heat, protecting the circuit from any damage. Thanks to its optimized design, the VIS800 series is able to absorb a large voltage surge and withstand high levels of continuous operating voltage.

The VIS800 series is also designed for convenient installation. It comes in two versions, a single-lead package and a dual-lead package, allowing it to be used in a wide range of applications. Unlike traditional GDTs, the VIS800 series does not require special spacers for mounting and can connection directly to the device in question, greatly simplifying integration into an existing system. Moreover, the VIS800 series has screw terminals for custom mounting and a special o-ring seal that helps to ensure reliable electrical performance.

Overall, the VIS800 series provides reliable protection and convenient installation, making it an ideal choice for protecting sensitive circuits against overvoltage events. Its highly reliable performance in high power applications and harsh environments makes it one of the most reliable GDTs available on the market. It is also easy to integrate into existing systems using its convenient screw terminals and o-ring seal.
