The 2R550TK-8 Gas Discharge Tube (GDT) from RUILON is a high-performance surge protection device engineered for medium-to-high voltage applications requiring robust and stable overvoltage suppression. Utilizing advanced ceramic gas discharge technology, this DIP series component provides rapid response to lightning strikes, switching transients, and high-energy surge events.
With a nominal static breakdown voltage of approximately 550V, the 2R550TK-8 offers an elevated protection threshold compared to lower voltage GDTs, effectively minimizing nuisance triggering while maintaining strong surge suppression capability. Its ultra-fast breakdown time of less than 50 ns ensures immediate activation, safeguarding sensitive electronic 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 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 circuit parameters, ensuring long service life and reliability. Encased in a durable DIP package, the 2R550TK-8 allows easy through-hole mounting and secure integration into various circuit designs.
