GDTs, or Gas Discharge Tube Arresters, are essential surge protection components used in a wide variety of electrical application fields. It is important to be familiar with the working principle and of the specific B88069X7050B502 GDT due to their critical role in mitigating risk of damage from electrical surges. This article will discuss the general working principle of GDTs, provide an overview of the typical application fields, and provide an in-depth examination of the B88069X7050B502.

General Working Principle

Fundamentally, GDTs act as a sacrificial component protecting the target electronic device from electrical surges. With any electrical surge arrester, they include a spark gap composed of lead-filled ceramic rings with a metal electrode. The spark gap acts as a protection barrier which is able to start “jumping” when the surge current flows in it.

When a transient or surge voltage is above the rating, the GDTs will fire, diverting the charge current away from the protected device. After the surge, the GDT will reset itself and become normal. In this way, GDTs can protect against transient overcurrents such as EFT and lightning discharges, as well as defend against permanent magnetism.

Application Fields

GDTs are typically used in a variety of applications where electric devices are subject to transient overvoltage or abnormal current surges. Various items in home, like computers, audio and video equipment, and automatic control devices are typically protected with GDTs. Industrial systems, like semiconductor production and automative production plants, also make use of GDTs. Another popular application for GDTs is the protection of telecommunications equipment. In residential homes, GDTs can be used to protect phones, computers, TVs, and other electrical devices.
