The 2R250TK-8 Gas Discharge Tube (GDT) from RUILON is a high-reliability surge protection device designed for efficient overvoltage suppression in low to medium voltage applications. Utilizing advanced ceramic gas discharge technology, this DIP series component ensures rapid response to lightning surges, switching transients, and other high-energy disturbances.
With a nominal static breakdown voltage of approximately 250V, the 2R250TK-8 provides a well-balanced protection threshold, offering improved stability compared to lower voltage GDTs while maintaining effective surge protection. 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 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, ensuring long-term reliability in demanding environments. Additionally, it maintains stable performance across switching frequencies up to 200 Hz, making it suitable for dynamic surge conditions.
Encased in a robust DIP package, the 2R250TK-8 allows easy through-hole mounting and strong mechanical stability. It is widely used in telecommunications, power supply systems, industrial control equipment, and surge protection modules.
