2R075TB-8 75V Gas Discharge Tube – 2RB-5 Package | RUILON
RUILON
The 2R075TB-8 Gas Discharge Tube (GDT) from RUILON is a compact, high-reliability ceramic surge protection device designed to protect sensitive electronic circuits from transient overvoltage events such as lightning strikes, switching surges, and electrostatic discharge (ESD). Built with advanced gas discharge technology, it delivers fast response and stable long-term protection performance in demanding environments.
With a DC spark-over voltage of 75V, this component is optimized for low-voltage protection applications requiring fast and precise triggering. Compared to higher-voltage GDT variants, it ensures earlier activation to effectively safeguard sensitive electronic components while maintaining stable operation. The device supports high impulse discharge current (8/20µs) and provides excellent impulse spark-over performance (1kV/µs), ensuring reliable surge suppression under harsh conditions.
The device features low capacitance at 1 MHz, preserving signal integrity in high-speed communication lines, while high insulation resistance reduces leakage current and improves efficiency. Stable glow voltage and arc voltage characteristics ensure consistent performance and extended service life.
Encased in a compact 2RB-5 package, the 2R075TB-8 allows easy integration into space-constrained PCB 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.
