The 2R350LB-8TH Gas Discharge Tube (GDT) from RUILON is a high-reliability ceramic surge protection device designed to protect electronic circuits from transient overvoltage events such as lightning strikes and switching surges. With a 350V DC spark-over voltage, this component is well-suited for medium- to high-voltage applications requiring stable and dependable protection.
Manufactured using advanced gas discharge technology, the 2R350LB-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 communication and control systems. Its ability to handle high impulse discharge current (8/20µs waveform) ensures excellent surge absorption and extended service life.
Compared to lower voltage GDT variants, the 350V model offers improved resistance to false triggering while maintaining effective surge suppression. The 2RL-8TH through-hole package provides strong mechanical durability and reliable performance in harsh operating conditions.
This GDT is widely used in telecommunications equipment, power supplies, industrial automation systems, signal line protection, and surge protection devices (SPD), delivering consistent and long-lasting circuit protection.
