Gas Discharge Tube Arresters (GDT) are used to protect electrical components from the effects of power surges. The B88069X4930S102 application field of GDT is designed to protect AC line-interactive power supplies, digital communications wiring, telephone main lines, and other sensitive installations. Moreover, GDTs are used to protect energy and communication systems against overvoltage surges.

A B88069X4930S102 is a Gas Discharge Tube Arrester (GDT) with very high surge handling capacity. GDTs are also known as Gas Discharge Tubes (GDTs) since they contain a gas-filled hollow glass cylinder. The GDT is a spark gap device with an internal glass envelope. When voltage or electrical spark disturbances reach a certain level, the gas contained in this tube will ionize and create a conductive path through the electrode system. The conductive path then guides the voltage surge energy to ground.

The B88069X4930S102 is designed to offer robust surge protection features such as high surge levels, high temperature performance, wide operating temperature range, and single cycle operation. It is also capable of protecting against reverse polarity, hard switching and heavy dynamic current excursions. Its low leakage current, coupled with its low leakage resistance, makes this GDT an ideal solution for protecting applications requiring high levels of protection.

The working principle of the B88069X4930S102 GDT is based on the dielectric breakdown of the gas present in the tube. When a high voltage surge reaches the GDT, the gas filled within the glass envelope will breakdown and ionize, thus forming a conductive path for the surge current to flow to ground. The voltage threshold at which the gas discharge breakdown occurs is referred to as the arrester\'s “breakover voltage”. This breakover voltage is affected by the ambient temperature and the pressure in the gas. As the pressure increases, the current breaks down at a higher voltage and vice versa.

The B88069X4930S102 is designed to withstand high surge levels with low follow current and low leakage resistance at any applied voltage. This GDT features a durable construction that is designed to offer superior lightning performance in the most demanding applications. Additionally, the B88069X4930S102 is designed with an internal precision resistor to reduce the possible voltage at the electrodes during turn-on and provides protection against false turn-on of the GDT.

In conclusion, the B88069X4930S102 Gas Discharge Tube Arrester is designed to offer robust surge protection features coupled with higher voltage surge ratings. This GDT device is designed to withstand high surge levels with low follow current and low leakage resistance at any applied voltage. Its durable construction and internal precision resistor make this GDT ideal for protecting applications requiring high levels of protection.
