Gas Discharge Tube Arresters (GDT) are a type of device used to protect electronic circuits from high voltage surges. They work by diverting the surge current away from the circuit, and can thus prevent it from being destroyed. The 2036-42-B3LF is a type of GDT used in a wide range of applications, and this article will provide an overview of its field of use and working principle.

Applications:

The 2036-42-B3LF GDT arresters are primarily used for overvoltage protection for electronic circuits in industrial and consumer electronics. These arresters can be seen in power supplies, computers, mobile phones, radiators, and even some appliances. Other potential applications include automotive and power stations, where transient voltages can change rapidly. In these cases, the arresters are able to divert the power away from the circuit so that damage can be avoided.

The arresters are also used in CATV systems, where they help to prevent damage from lightning and other surges. CATV systems are especially susceptible to voltage spikes caused by lighting, and the arresters can help to protect both the system and the electronics connected to it.

In safety-critical systems like medical devices, crash test dummies, or diagnostic equipment, the 2036-42-B3LF can provide additional protection from static electricity, switching transients, and electrostatic discharge.

Working Principle:

The 2036-42-B3LF are gas discharge tube arresters, which operate by using a gas within a sealed electrode. The tube contains a special gas, such as sulfur hexafluoride, argon, or xenon, that ionizes when voltage surges occur. This ionization of the gas causes electrons to become excited and begin to flow through the tube, creating a negative voltage that will counteract the high voltage of the surge, and thus, dissipating the surge energy.

During normal operation, the voltage across the GDT is very low, and current does not flow through it. However, when a surge occurs, the voltage rises and the tube will ionize to conduct current and divert the surge energy away from the circuit. The current then flows through the arrester to the ground, and the surge is dissipated.

Once the surge has passed, the current subsides and the tube de-ionizes, returning to its original low-voltage state. As such, the GDT will not be damaged by the surge, and can continue to provide protection.

In addition to this surge protection, the 2036-42-B3LF also offers protection against electrostatic discharge and long-term voltage fluctuations. By working to divert the surge energy, the GDT also protects the delicate electronics within the circuit from damage.

The 2036-42-B3LF GDT arresters are used in a wide variety of applications, and offer reliable protection against high voltage surges and electrostatic discharges. Their gas-filled design helps to divert the surge energy away from the sensitive electronics, and thus, enabling them to continue to operate without damage.
