SMD5050-350NB 350V Gas Discharge Tube – SMD5050-B Package | RUILON
RUILON
The SMD5050-350NB Gas Discharge Tube (GDT) from RUILON is a high-reliability ceramic surge protection component designed to safeguard electronic circuits against transient overvoltage events such as lightning strikes, switching surges, and electrostatic discharge (ESD). Built with advanced gas discharge technology, it ensures fast response and consistent protection performance in demanding environments.
With a DC spark-over voltage of 350V, this device is ideal for medium to high-voltage applications, offering an optimal balance between sensitivity and stability. Compared to lower-voltage GDT variants, it reduces the risk of false triggering while maintaining strong surge suppression capability. The component supports high impulse discharge current (8/20µs) and features excellent impulse spark-over performance (1kV/µs), making it suitable for harsh electrical conditions.
The device features low capacitance at 1 MHz, preserving signal integrity in high-speed communication systems, along with high insulation resistance to minimize leakage current. Stable glow voltage and arc voltage characteristics contribute to long service life and reliable operation.
Encased in a compact SMD5050-B package, the SMD5050-350NB allows easy surface-mount installation and flexible PCB layouts. It is widely used in telecommunications equipment, power supplies, industrial automation, smart meters, and consumer electronics, delivering dependable surge protection and enhanced system reliability.
