Gas Discharge Tube Arresters (GDT) are devices, often referred to as surge arresters, spark gaps, or surge protectors, used to protect electrical circuits, equipment, and networks from damage due to overvoltage transients caused by lightning or power system faults. The B88069X6350T602 is a type of GDT arrestor designed to selectively limit overvoltage transients, thus protecting the electronic components connected in series with it. In this article, we will discuss the application field and working principle of the B88069X6350T602.

Application Field

The B88069X6350T602 is a 4-pin dual-function GDT arrester, designed to be used in many applications, including:

• DC power systems, including solar inverters, frequency drives, and DC-DC converters.
• Computer servers, telecommunications systems, and other data processing equipment.
• Industrial equipment, including robotic systems and CNC machines.
• High-end consumer electronics, including televisions, audio equipment, and gaming consoles.

The B88069X6350T602 can also be used to protect sensitive electronic systems from transient overvoltage events such as lightning strikes, power-line surges, and short circuits. This type of GDT arrester is suitable for use in environments where temperatures can range from -40°C to +85°C.

Working Principle

A GDT arrester consists of a tube filled with noble gas and electrodes at each end of the tube. The electrodes are surrounded by an insulating material and when an overvoltage transient occurs, the gas in the tube ionizes and becomes conductive, allowing current to flow between the electrodes. This process acts to limit the overvoltage to a safe level. The B88069X6350T602 also contains a Zener diode, which is used for protecting surge current.

The gas in the tube is specifically chosen so that it will ionize easily at the desired overvoltage and, as it ionizes, it becomes more conductive, thus limiting the overvoltage further. The resistance of the tube therefore reduces as the overvoltage increases, until the tube is completely conducting and the circuit is protected from damage. The B88069X6350T602 also features a Zener diode, which provides additional protection against surge current.

The B88069X6350T602 is designed to protect against both common mode and differential mode overvoltage transients. Common mode transients, also known as power line surges, are created when the voltage on one side of a circuit is suddenly higher than on the other side. Differential mode transients occur when both sides of a circuit are affected, such as when lightning strikes nearby. The B88069X6350T602 is capable of limiting the overvoltage in both scenarios.

Conclusion

The B88069X6350T602 is a GDT arrester designed to protect against transient overvoltage events such as lightning strikes, power-line surges, and short circuits. This type of GDT arrester is suitable for use in environments where temperatures can range from -40°C to +85°C and is capable of limiting both common mode and differential mode transients. The B88069X6350T602 is designed for use in many applications, including DC power systems, servers and telecom systems, industrial equipment, and consumer electronics. It is also equipped with a Zener diode for additional protection against surge current.
