SMD5050-470NA 470V Gas Discharge Tube – SMD5050 Package | RUILON
RUILON
The SMD5050-470NA Gas Discharge Tube (GDT) from RUILON is a high-reliability ceramic surge protection device designed to safeguard electronic circuits from high-energy transient voltages. Built using advanced gas discharge technology, it delivers fast response to lightning surges, switching transients, and ESD events, ensuring robust and consistent protection.
With a DC spark-over voltage of 470V, this device is well-suited for high-voltage applications, offering improved stability and minimizing the risk of premature triggering compared to lower-voltage GDT variants. It supports high impulse discharge current (8/20µs) and strong impulse withstanding voltage capability, making it ideal for harsh electrical environments.
The low capacitance at 1 MHz ensures minimal signal distortion, making it suitable for sensitive communication lines, while high insulation resistance reduces leakage current and enhances efficiency. Stable glow voltage and arc voltage characteristics contribute to long service life and dependable performance.
Encased in a compact SMD5050 package, the device allows easy surface-mount integration and flexible PCB design. It is widely used in telecommunications, industrial equipment, power systems, smart meters, and consumer electronics, providing superior protection and long-term reliability.
