Gas Discharge Tube Arresters (GDT) are a special type of electrical component that is designed to protect circuits and equipment from high voltage and/or electrical transients. B88069X0190S102 specifically refers to an arrestor that is designed to protect automotive electronic devices from voltage spikes caused by events such as lightning strikes and driving on rough terrain.

Application Field

Primary applications for the B88069X0190S102 include automotive applications such as car stereos, dashboards, radios, and other equipment that requires protection from electrical surges. In addition, this GDT arrester can also be used to protect other types of electronic equipment from voltage transients and other electrical disruption. Ultimately, the B88069X0190S102 will be a good fit for any application where protection against voltage spikes is needed.

Working Principle

GDT Arresters operate by utilizing the reverse breakdown operation of gas-filled tubes. The Gas Discharge Tube is filled with noble gases, such as argon, nitrogen, helium, neon, and air. Each gas has its own breakdown region. The air filled tubes are superior to the other gases in terms of noise level but, depending upon the application, GDTs may be filled with any of these gases. GDTs have a triggering voltage that must be exceeded before the gas can break down and conduct current. When the B88069X0190S102 is subjected to a voltage surge exceeding the triggering voltage, the gas in the tube breaks down, forming a spark gap. This spark gap conducts current until it is shorted out. The shorting force is typically provided by a built-in resistor (such as a varistor component) which limits the maximum current to a safe level.

In summary, the B88069X0190S102 Gas Discharge Tube Arrestor is designed to protect circuits and equipment from high voltage transients and electrical surges. This device is primarily used in automotive applications such as car radios, dashboards, and other electronic devices. It operates on the principle of reverse breakdown operation of a gas-filled tube, which will short out the voltage surge and limit the current to a safe level.
