2R800LB-8TH 800V Gas Discharge Tube (GDT) Surge Protector – 2RL-8TH Package | RUILON

The 2R800LB-8TH Gas Discharge Tube (GDT) from RUILON is a high-voltage ceramic surge protection device designed to protect electronic systems from extreme transient overvoltage events such as lightning strikes and switching surges. With an 800V DC spark-over voltage, this component is ideal for applications requiring high voltage tolerance and enhanced surge protection reliability.

Built using advanced gas discharge technology, the 2R800LB-8TH ensures stable impulse spark-over voltage at 1KV/µs, along with high insulation resistance and low capacitance at 1 MHz, minimizing signal distortion in sensitive communication and control circuits. Its capability to withstand high impulse discharge current (8/20µs waveform) provides excellent surge absorption and long service life.

Compared to lower voltage GDT variants, the 800V model offers improved resistance to false triggering in higher operating voltage environments, making it well-suited for industrial and power-related applications. The 2RL-8TH through-hole package ensures strong mechanical durability and reliable performance under demanding conditions.

This GDT is widely used in power supplies, telecommunications equipment, industrial automation systems, signal line protection, and surge protection devices (SPD), delivering dependable and long-lasting circuit protection.
