The 2R250TK-5 Gas Discharge Tube (GDT) from RUILON is a high-reliability surge protection component designed for effective overvoltage suppression in low to medium voltage applications. Utilizing advanced ceramic gas discharge technology, this DIP series device ensures rapid response to transient events such as lightning surges, switching disturbances, and electrostatic discharge.
With a nominal static breakdown voltage of approximately 250V, the 2R250TK-5 provides precise protection with optimized ignition characteristics. It features an ultra-fast breakdown time of less than 50 ns, enabling immediate clamping of surge energy to safeguard sensitive electronic components. The device demonstrates stable first ignition performance even after extended periods of inactivity, along with consistent following ignition values during continuous operation.
Designed for durability, the GDT supports high peak discharge current capability (~300A) and maintains reliable electrical life across extensive switching operations. Compared to lower voltage GDTs, it offers slightly higher voltage tolerance, reducing the risk of nuisance triggering while maintaining effective protection.
The robust DIP package allows easy through-hole mounting and strong mechanical stability, making it suitable for industrial and power applications. The 2R250TK-5 is widely used in telecom systems, power supplies, industrial controls, and consumer electronics requiring dependable surge protection.
