SMD5050-800NA 800V Gas Discharge Tube – SMD4042 Package | RUILON
RUILON
The SMD5050-800NA Gas Discharge Tube (GDT) from RUILON is a high-voltage ceramic surge protection device engineered to protect sensitive electronics from extreme transient overvoltage events. Utilizing advanced gas discharge technology, it provides rapid response to lightning strikes, switching surges, and electrostatic discharge (ESD), ensuring reliable and long-term circuit protection.
With a DC spark-over voltage of 800V, this component is ideal for high-voltage applications where enhanced stability and higher surge thresholds are required. Compared to lower-voltage GDT series, it minimizes false triggering while maintaining strong surge protection performance. The device supports high impulse discharge current (8/20µs) and features excellent impulse spark-over characteristics (1kV/µs), making it suitable for harsh and demanding environments.
It offers low capacitance at 1 MHz, preserving signal integrity in high-speed communication lines, along with high insulation resistance to reduce leakage current. Stable glow voltage and arc voltage performance ensure consistent operation and extended service life.
Housed in a compact SMD4042 package, the SMD5050-800NA allows easy surface-mount integration and flexible PCB layout design. It is widely used in telecommunications, industrial automation, power systems, smart grid infrastructure, and consumer electronics, delivering dependable surge protection and system reliability.
