The 2R300TK-8 Gas Discharge Tube (GDT) from RUILON is a high-performance surge protection component designed for medium-voltage applications requiring reliable and stable overvoltage protection. Built with advanced ceramic gas discharge technology, this DIP series device provides rapid response to lightning surges, switching transients, and other high-energy disturbances.
With a nominal static breakdown voltage of approximately 300V, the 2R300TK-8 offers an optimized balance between protection sensitivity and system stability. Compared to lower voltage GDTs, it reduces the likelihood of nuisance triggering while maintaining strong surge suppression capability. Its ultra-fast breakdown time of less than 50 ns ensures immediate activation, protecting sensitive circuits from damage.
The device features consistent ignition characteristics, including stable first ignition performance after prolonged inactivity and reliable following ignition values 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 repeated surge conditions.
Encased in a robust DIP package, the 2R300TK-8 allows easy through-hole mounting and secure integration into various circuit designs. It is widely used in telecommunications, power supply systems, industrial automation, and surge protection modules.
