2R090LB-8TH 90V Gas Discharge Tube (GDT) Surge Protector – 2RL-8TH Package | RUILON

RUILON

The 2R090LB-8TH Gas Discharge Tube (GDT) from RUILON is a compact and highly reliable ceramic surge protection device designed to protect low-voltage electronic circuits from transient overvoltage events such as lightning surges and switching spikes. With a 90V DC spark-over voltage, this component is ideal for sensitive applications requiring fast and precise protection.

Built with advanced gas discharge technology, the 2R090LB-8TH offers stable impulse spark-over voltage at 1KV/µs, along with high insulation resistance and low capacitance at 1 MHz, ensuring minimal signal distortion in high-speed communication lines. Its strong capability to withstand high impulse discharge current (8/20µs waveform) provides excellent surge absorption and long operational life.

Compared to higher voltage GDT variants, the 90V model enables earlier clamping of transient surges, making it especially suitable for protecting low-voltage circuits and sensitive components. The 2RL-8TH through-hole package ensures robust mechanical strength and reliable performance in demanding environments.

This GDT is widely used in telecommunications equipment, signal line protection, consumer electronics, industrial control systems, and surge protection devices (SPD), delivering consistent and dependable circuit protection.
