The 2R300TK-5 Gas Discharge Tube (GDT) from RUILON is a high-performance surge protection device designed to provide reliable overvoltage protection in medium-voltage electronic circuits. Built with advanced ceramic gas discharge technology, this DIP series component ensures rapid response to transient events such as lightning surges, switching spikes, and electrical disturbances.
With a nominal static breakdown voltage of approximately 300V, the 2R300TK-5 offers a balanced protection threshold, making it ideal for applications requiring higher voltage tolerance than lower-rated GDTs. Its ultra-fast breakdown time of less than 50 ns ensures immediate activation, effectively diverting surge energy away from sensitive components. The device maintains stable first ignition values even after long periods of inactivity and consistent following ignition values during continuous operation.
Engineered for durability, the GDT supports high peak discharge current capability of up to ~500A, ensuring strong surge handling performance. It also demonstrates excellent electrical life characteristics with high switching reliability under repeated stress conditions. Compared to lower voltage models, this variant reduces nuisance triggering while maintaining efficient protection.
Encased in a robust DIP package, the 2R300TK-5 allows easy through-hole mounting and secure integration into industrial and power systems. It is widely used in telecom equipment, power supplies, industrial controls, and surge protection modules.
