Gas Discharge Tube Arresters (GDT)
Gas Discharge Tube Arresters (GDT) are circuit protection components used to protect electronic systems from high-energy surge events, lightning-induced transients and overvoltage conditions. They are widely used in communication equipment, power supplies, industrial control systems, telecom lines, networking devices, security systems, renewable energy equipment, meters and building electrical protection.
This category includes gas discharge tubes, GDT surge arresters, two-electrode GDTs, three-electrode GDTs, lightning protection arresters and related overvoltage protection components. These devices are commonly selected based on DC spark-over voltage, impulse discharge current, insulation resistance, capacitance, response characteristics, package type, safety standards and application requirements.
TomatoElec supplies original Gas Discharge Tube Arresters from recognized manufacturers such as Bourns, Littelfuse, TDK, EPCOS, Vishay, Eaton, Bel Fuse, Murata, Panasonic and other major brands. As an in-stock electronic components supplier and independent distributor, TomatoElec provides inventory support, original component sourcing and BOM sourcing services for global customers.
