The 2R550TK Gas Discharge Tube (GDT) from RUILON is a high-performance surge protection device designed for medium-to-high voltage applications requiring reliable and efficient overvoltage suppression. Utilizing advanced ceramic gas discharge technology, this DIP series component ensures rapid response to lightning strikes, switching transients, and other high-energy electrical disturbances.
With a nominal static breakdown voltage of approximately 550V, the 2R550TK provides a higher protection threshold compared to lower voltage GDTs, significantly reducing the risk of nuisance triggering while maintaining strong surge suppression capability. Its ultra-fast breakdown time of less than 50 ns enables immediate activation, effectively diverting surge energy away from sensitive electronic components.
The device features stable ignition characteristics, including reliable first ignition values after extended periods of inactivity and consistent following ignition performance 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 robust DIP package, the 2R550TK 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.
