Gas Discharge Tube Arresters (GDT) are crucial components used for overvoltage protection in electrical and electronic equipment. These devices operate by ionizing gas within a sealed tube to dissipate excess electrical energy, effectively safeguarding sensitive circuitry from potential damage caused by voltage spikes.

GDTs are renowned for their high surge handling capabilities and fast response times, making them an ideal solution for applications in telecommunications, power supplies, and industrial automation. They offer low capacitance and minimal leakage, ensuring consistent performance over time.

Leading manufacturers of Gas Discharge Tube Arresters include Littelfuse, Bourns, and EPCOS, each offering a wide range of specifications to meet the diverse needs of modern electronic systems. With robust construction and reliable performance, GDTs are a trusted choice for professionals seeking superior protection against transient voltage anomalies.
