2R450TK-5 450V DIP Gas Discharge Tube | Fast Switching GDT <50ns | High Surge Current ~600A | RUILON

The 2R400TK-8 Gas Discharge Tube (GDT) from RUILON is a high-reliability surge protection component designed for medium-voltage applications requiring precise and stable overvoltage protection. Utilizing advanced ceramic gas discharge technology, this DIP series device ensures rapid response to lightning strikes, switching transients, and other high-energy electrical disturbances.

With a nominal static breakdown voltage of approximately 400V, the 2R400TK-8 offers a higher protection threshold compared to lower voltage GDTs, significantly reducing nuisance triggering while maintaining strong surge suppression performance. Its ultra-fast breakdown time of less than 50 ns enables immediate activation, protecting sensitive circuits from transient damage.

The device features stable ignition characteristics, including reliable first ignition values after extended periods of inactivity and consistent following ignition behavior during continuous operation. It supports high switching durability of up to 2×10⁵ operations at +25°C and operates efficiently at switching frequencies up to 200 Hz, ensuring dependable performance under repetitive surge conditions.

Encased in a robust DIP package, the 2R400TK-8 allows easy through-hole mounting and secure integration into various circuit designs. It is widely used in telecommunications, power supply systems, industrial automation, and surge protection modules where consistent and reliable protection is essential.
