The 2R500TK-8 Gas Discharge Tube (GDT) from RUILON is a high-reliability surge protection device designed for medium-to-high voltage applications requiring robust and stable overvoltage suppression. Utilizing advanced ceramic gas discharge technology, this DIP series component ensures rapid response to lightning strikes, switching transients, and high-energy surge events.
With a nominal static breakdown voltage of approximately 500V, the 2R500TK-8 offers an increased protection threshold compared to lower voltage GDTs, significantly reducing nuisance triggering while maintaining strong surge suppression performance. 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 maintains stable performance at switching frequencies up to 200 Hz, ensuring dependable operation under repetitive surge conditions.
Designed for demanding environments, the GDT demonstrates strong surge handling capability under defined test conditions, ensuring long service life. Encased in a durable DIP package, the 2R500TK-8 allows easy through-hole mounting and secure integration into various circuit designs.
