The 2R800SK-8 SMD Gas Discharge Tube (GDT) from RUILON is an ultra-high voltage surge protection device engineered to protect electronic systems from severe transient overvoltage events such as lightning strikes, switching surges, and induced electrical disturbances. Utilizing advanced ceramic gas discharge technology, this component ensures ultra-fast switching by transitioning from a high-resistance state to a low-impedance conduction path, effectively diverting high-energy surge currents away from sensitive circuitry.
With a nominal spark-over voltage of approximately 800V, the 2R800SK-8 is ideal for applications requiring very high voltage tolerance and maximum surge protection capability. Compared to lower-voltage GDT variants, it provides significantly enhanced energy handling capacity and improved durability, making it suitable for harsh industrial, telecom, and power infrastructure environments. The device also features high insulation resistance and ultra-low capacitance, ensuring minimal impact on high-frequency signal integrity.
Designed for long-term reliability, the component supports high impulse discharge current capability (8/20 µs waveform) and maintains consistent performance under repetitive surge conditions. Its stable glow and arc voltage characteristics contribute to dependable operation in demanding applications.
The compact SMD package design allows efficient PCB integration and supports automated SMT assembly processes, making it ideal for high-density and space-constrained electronic systems.
