Gas discharge tubes (GDTs) are electrical components designed to protect sensitive electronics from transient overvoltages, often referred to as surges or spikes. GDTs can be used to protect electronic components in both AC and DC current, at frequencies ranging from DC up to 300 KHz or more.

GDTs are made up of a sealed glass tube filled with a noble gas such as Argon or Xenon. Generally, the electrodes are made from zinc and the center electrode is made from copper. When an overvoltage surges through a GDT, the gas inside the tube breaks down, and a relatively low-resistance path is created to allow the surge current to travel through. This path will remain until the voltage drops back below the device’s “breakover” voltage, after which the gas will recombine and the path is broken again. In this respect, GDTs are analogous to electrical fuses.

GDTs are often used in the protection of telecommunications, industrial and power electronics systems. In such systems, the GDT is typically placed inline with the protected device, in parallel with the power line. GDTs are also used to protect sensitive electronics from electrostatic discharge, such as in laboratory and medical equipment and in devices exposed to high-electrostatic fields, such as elevator shafts.

GDTs have many advantages over other forms of surge protection. They are highly reliable and quick-acting, with no mechanical parts to wear out and no need for manual resetting. They are also extremely compact, with no need for bulky gas cylinders and external circuits. Finally, GDTs have a high reliability and extremely low failure rate, providing excellent protection from transient overvoltages.

One of the most popular GDTs is the 2015-SMH-RPLF which is an ultra-fast-reacting, high-performance GDT for telecom and industrial applications. This GDT is rated for 32A continuous current, with a peak surge current up to 220A. It has a surge withstand capability of 7000 joules and a maximum voltage of 24V DC. This GDT is suitable for both AC and DC applications, and is designed specifically for harsh operating environments.

The working principle of the 2015-SMH-RPLF GDT is based on the Zener breakdown phenomenon, which occurs when a voltage above the “breakover” voltage is applied to the device. When this occurs, the gas inside the tube is ionized, which creates a path for the surge current to travel through the GDT until the voltage drops below the breakover value. The gas then recombines, breaking the path and protecting the device from the surge.

GDTs provide a high level of protection against transient overvoltages, and the 2015-SMH-RPLF is one of the most popular GDTs used in industrial and telecommunications applications. Its high performance, reliability, and quick-acting protection make it an excellent choice for protecting sensitive electronics from transient overvoltages.
