SMD5050-090NB 90V Gas Discharge Tube – SMD5050-B Package | RUILON
RUILON
The SMD5050-090NB Gas Discharge Tube (GDT) from RUILON is a compact and high-reliability ceramic surge protection device designed to safeguard sensitive electronic circuits from transient overvoltage events. Utilizing advanced gas discharge technology, it provides rapid response to lightning strikes, switching surges, and electrostatic discharge (ESD), ensuring consistent and long-term circuit protection.
With a DC spark-over voltage of 90V, this device is ideal for low-voltage applications requiring precise and early protection. Compared to higher-voltage GDT series, it enables faster triggering to protect sensitive components from damage while maintaining stable operation. The component supports high impulse discharge current (8/20µs) and features excellent impulse spark-over performance (1kV/µs), making it suitable for demanding environments.
The device offers low capacitance at 1 MHz, ensuring minimal signal distortion in high-speed communication lines, while high insulation resistance reduces leakage current and improves efficiency. Stable glow voltage and arc voltage characteristics contribute to long service life and reliable performance.
Encased in a compact SMD5050-B package, the SMD5050-090NB enables easy surface-mount installation and flexible PCB layouts. It is widely used in telecommunications equipment, power supplies, industrial controls, smart meters, and consumer electronics, delivering dependable surge protection and enhanced system reliability.
