2R400TB-8(BVL) 400V Gas Discharge Tube – 2RB-8(BVL) Package | RUILON
RUILON
The 2R400TB-8(BVL) Gas Discharge Tube (GDT) from RUILON is a high-performance ceramic surge protection device designed to protect sensitive 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 delivers ultra-fast response and stable long-term protection in harsh electrical environments.
With a DC spark-over voltage of 400V, this component is optimized for medium to high-voltage surge protection applications, providing a strong balance between protection sensitivity and operational stability. Compared to lower-voltage GDT variants, it significantly reduces false triggering while ensuring effective suppression of severe transient surges. The device supports high impulse discharge current (8/20µs) and offers excellent impulse spark-over performance (1kV/µs) for reliable protection under demanding conditions.
The device features low capacitance at 1 MHz, helping preserve 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, and extended service life.
Encased in a compact 2RB-8(BVL) package, the 2R400TB-8(BVL) offers flexible PCB integration for space-constrained designs. It is widely used in telecommunications equipment, power supplies, industrial automation systems, smart meters, and consumer electronics, delivering dependable surge protection and enhanced system reliability.
