SMD5050-470NB 470V Gas Discharge Tube – SMD5050-B Package | RUILON

RUILON

The SMD5050-470NB Gas Discharge Tube (GDT) from RUILON is a high-performance ceramic surge protection device designed to protect electronic circuits from high-energy transient overvoltage events. Utilizing advanced gas discharge technology, it delivers fast and reliable response to lightning strikes, switching surges, and electrostatic discharge (ESD), ensuring long-term circuit protection and system stability.

With a DC spark-over voltage of 470V, this component is well-suited for medium to high-voltage applications, offering enhanced stability and reduced risk of false triggering compared to lower-voltage GDT series. It provides strong impulse spark-over performance (1kV/µs) and supports high impulse discharge current (8/20µs), making it ideal for use in harsh and surge-prone environments.

The device features low capacitance at 1 MHz, helping preserve signal integrity in high-speed communication systems, while high insulation resistance minimizes leakage current and improves efficiency. Stable glow voltage and arc voltage characteristics ensure consistent performance and extended service life.

Encased in a compact SMD5050-B package, the SMD5050-470NB allows easy surface-mount assembly and flexible PCB layouts. It is widely used in telecommunications equipment, power supplies, industrial systems, smart meters, and consumer electronics, delivering dependable surge protection and enhanced system reliability.
