2R600LB-8TH 600V Gas Discharge Tube (GDT) Surge Protector – 2RL-8TH Package | RUILON

The 2R600LB-8TH Gas Discharge Tube (GDT) from RUILON is a high-reliability ceramic surge protection device engineered to protect electronic systems from high-energy transient overvoltage events such as lightning strikes and switching surges. Featuring a 600V DC spark-over voltage, this component is ideal for high-voltage applications requiring stable and robust protection performance.

Manufactured using advanced gas discharge technology, the 2R600LB-8TH provides stable impulse spark-over voltage at 1KV/µs, along with high insulation resistance and low capacitance at 1 MHz, ensuring minimal signal distortion in sensitive communication and control circuits. Its strong capability to handle high impulse discharge current (8/20µs waveform) enables effective surge absorption and long service life.

Compared to lower voltage GDT variants, the 600V model significantly reduces the risk of false triggering in higher operating voltage environments while maintaining reliable surge protection. The 2RL-8TH through-hole package ensures excellent mechanical strength and dependable 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 consistent and long-lasting circuit protection.
