SMD5050-800NA 800V Gas Discharge Tube – SMD5050 Package | RUILON
RUILON
The SMD5050-800NA Gas Discharge Tube (GDT) from RUILON is a high-voltage ceramic surge protection device designed to provide reliable protection against extreme transient overvoltage events. Built with advanced gas discharge technology, it delivers rapid response to lightning surges, switching transients, and electrostatic discharge (ESD), ensuring enhanced circuit safety and durability.
With a DC spark-over voltage of 800V, this device is optimized for high-voltage applications where greater tolerance and stability are required. Compared to lower-voltage GDT series, it significantly reduces the risk of nuisance triggering while maintaining strong protection performance. The component supports high impulse discharge current (8/20µs) and offers excellent impulse spark-over characteristics (1kV/µs), making it suitable for harsh electrical environments.
Its low capacitance at 1 MHz helps maintain signal integrity in high-speed communication systems, while high insulation resistance ensures minimal leakage current. Stable glow voltage and arc voltage characteristics contribute to long operational life and consistent performance over time.
Encased in a compact SMD5050 package, the SMD5050-800NA allows easy surface-mount installation and flexible PCB design. It is widely used in telecommunications, industrial systems, power infrastructure, smart grid solutions, and consumer electronics, delivering dependable and long-lasting surge protection.
