2R350TA-5 350V Gas Discharge Tube – 2RA-5 Package | RUILON
RUILON
The 2R350TA-5 Gas Discharge Tube (GDT) from RUILON is a high-performance ceramic surge protection device designed to safeguard electronic circuits from high-energy transient overvoltage events such as lightning strikes, switching surges, and electrostatic discharge (ESD). Built with advanced gas discharge technology, it ensures rapid response and reliable long-term protection in demanding environments.
With a DC spark-over voltage of 350V, this component is ideal for medium to high-voltage applications, offering a well-balanced protection threshold that minimizes false triggering while maintaining strong surge suppression capability. Compared to lower-voltage GDT variants, it provides enhanced operational stability and dependable performance. The device supports high impulse discharge current (8/20µs) and features excellent impulse spark-over performance (1kV/µs), making it suitable for surge-prone environments.
The device features low capacitance at 1 MHz, preserving signal integrity in high-speed communication systems, while high insulation resistance reduces leakage current and improves efficiency. Stable glow voltage and arc voltage characteristics ensure consistent operation and extended service life.
Encased in a compact 2RA-5 package, the 2R350TA-5 is ideal for space-constrained PCB designs and allows easy integration. It is widely used in telecommunications equipment, power supplies, industrial automation systems, smart meters, and consumer electronics, delivering reliable surge protection and enhanced system durability.
