The 2R630TK-8 Gas Discharge Tube (GDT) from RUILON is a high-voltage surge protection component engineered for demanding applications requiring reliable and efficient overvoltage suppression. Utilizing advanced ceramic gas discharge technology, this DIP series device provides rapid response to lightning strikes, switching transients, and high-energy surge events.
With a nominal static breakdown voltage of approximately 630V, the 2R630TK-8 offers an elevated protection threshold, making it ideal for circuits that require higher voltage tolerance compared to lower-rated GDTs. This helps reduce nuisance triggering while ensuring strong surge suppression performance. Its ultra-fast breakdown time of less than 50 ns enables immediate activation, effectively protecting sensitive electronic components from transient damage.
The device features stable ignition characteristics, including consistent first ignition values after prolonged inactivity and reliable 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 under repetitive surge conditions.
Designed for harsh electrical environments, the GDT demonstrates strong surge handling capability under defined test parameters, ensuring long service life. Encased in a robust DIP package, the 2R630TK-8 allows easy through-hole mounting and secure integration into various circuit designs.
