The 2R400TK-5 Gas Discharge Tube (GDT) from RUILON is a high-reliability surge protection component designed for medium-voltage applications requiring stable and efficient overvoltage protection. Utilizing advanced ceramic gas discharge technology, this DIP series device delivers rapid response to transient events such as lightning surges, switching spikes, and electrical disturbances.
With a nominal static breakdown voltage of approximately 400V, the 2R400TK-5 provides a higher protection threshold compared to lower voltage GDTs, effectively reducing the risk of nuisance triggering while maintaining strong surge suppression capability. Its ultra-fast breakdown time of less than 50 ns ensures immediate activation, protecting sensitive circuits from high-energy transients.
The device demonstrates stable ignition characteristics, including reliable first ignition performance after extended periods of inactivity and consistent following ignition values during continuous operation. It supports high peak discharge current capability of up to ~500A, ensuring excellent surge handling performance. Its robust electrical life and high switching durability make it suitable for repeated surge conditions.
Encased in a durable DIP package, the 2R400TK-5 enables easy through-hole mounting and strong mechanical stability. It is widely used in telecommunications, power supply systems, industrial automation, and surge protection modules requiring dependable performance.
