Gas Discharge Tube Arresters (GDT) are designed to protect electronic devices from electrical transients, such as those caused by lightning strikes. The 2026-15-C18 arrester is a device that is used to protect equipment and circuits from electrical surge damage due to lightning, switching transients, and static discharge. It is an adjustable type voltage arrester, consisting of a gas discharge tube, a silicon avalanche diode, and a metal oxide varistor in series combination.

The gas discharge tube consists of two electrodes sealed in a glass tube. When the voltage across the tube increased, the gas breaks down and forms a low resistance channel that allows current to flow. The avalanche diode consists of a reverse biased PN junction that is capable of blocking voltages up to a certain voltage and then passes current at a very high rate. The metal oxide varistor is a variable resistor with a highly nonlinear current-voltage characteristic that is used to limit the peak voltages created by transients.

The 2026-15-C18 gas discharge tube arrester can be used to protect equipment in a wide variety of applications, including automotive, telecommunication, industrial, and energy systems. The device can be used for lightning strike protection, protection from switching transient, static discharge, and withstanding events up to 20 kA. The working voltage of the arrester is adjustable, from 17-21 V, allowing it to be tailored to the specific application.

In operation, the 2026-15-C18 arrester blocks low transient voltages and conducts high transient current. It is designed to clamp the peak voltage to a safe value, protect equipment from overvoltage and surge damage, and suppress electromagnetic pollution generated by the surge current. The device has a fast reaction time, and can suppress large disturbances within a few microseconds.

The 2026-15-C18 GDT arrester is a valuable tool for protecting equipment from electrical transients such as those caused by lightning strikes. It can be used in a wide range of applications, and has adjustable voltage levels that allow it to be suitably tailored for each application. Additionally, it offers fast response times and can suppress large disturbances within a few microseconds, providing effective protection from overvoltage and surge damage.
