2R230TD-8 230V Gas Discharge Tube – 2RD-8 Package | RUILON
RUILON
The 2R230TD-8 Gas Discharge Tube (GDT) from RUILON is a high-reliability ceramic surge protection device designed to protect electronic circuits from high-energy transient overvoltage events such as lightning strikes, switching surges, and electrostatic discharge (ESD). Using advanced gas discharge technology, it provides ultra-fast response and stable long-term protection in demanding electrical environments.
With a DC spark-over voltage of 230V, this component is optimized for medium-voltage surge protection applications, offering a strong balance between sensitivity and stability. Compared to lower-voltage GDT variants, it reduces false triggering while still ensuring fast activation during surge events. The device supports high impulse discharge current (8/20µs) and delivers excellent impulse spark-over performance (1kV/µs) for reliable and effective surge suppression.
The device features low capacitance at 1 MHz, helping maintain signal integrity in high-speed communication systems, while high insulation resistance minimizes leakage current and improves overall efficiency. Stable glow voltage and arc voltage characteristics ensure consistent operation, strong energy handling capability, and long service life under repeated surge conditions.
Encased in a compact 2RD-8 package, the 2R230TD-8 is easy to integrate into space-constrained PCB designs. It is widely used in telecommunications equipment, power supplies, industrial automation systems, smart meters, and consumer electronics, providing dependable surge protection and improved system reliability.
