The 2R470TK-5 Gas Discharge Tube (GDT) from RUILON is a high-reliability surge protection component designed for medium-to-high voltage applications requiring stable and efficient overvoltage protection. Built with advanced ceramic gas discharge technology, this DIP series device ensures rapid response to lightning surges, switching transients, and other high-energy disturbances.
With a nominal static breakdown voltage of approximately 470V, the 2R470TK-5 provides an elevated protection threshold compared to lower voltage GDTs, reducing nuisance triggering while maintaining strong surge suppression performance. Its ultra-fast breakdown time of less than 50 ns ensures immediate activation, effectively protecting sensitive electronic 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 repeated surge conditions.
Encased in a robust DIP package, the 2R470TK-5 allows easy through-hole mounting and secure integration into a wide range of circuit designs. It is widely used in telecommunications, power supply systems, industrial automation, and surge protection modules where consistent and reliable protection is essential.
