2R450TK-8 450V DIP Gas Discharge Tube | Fast Switching GDT <50ns | High Surge Durability | RUILON
RUILON
The 2R450TK-8 Gas Discharge Tube (GDT) from RUILON is a high-performance surge protection device engineered for medium-to-high voltage applications requiring stable and reliable overvoltage protection. Built with advanced ceramic gas discharge technology, this DIP series component provides rapid response to lightning surges, switching transients, and other high-energy electrical disturbances.
With a nominal static breakdown voltage of approximately 450V, the 2R450TK-8 offers an elevated protection threshold compared to lower voltage GDTs, significantly reducing nuisance triggering while maintaining strong surge suppression capability. Its ultra-fast breakdown time of less than 50 ns ensures immediate activation, effectively protecting sensitive electronic components from transient damage.
The device features stable ignition characteristics, including reliable first ignition performance after extended inactivity and consistent following ignition values 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 in repetitive surge environments.
Encased in a durable DIP package, the 2R450TK-8 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 robust protection is essential.
