The 3R600TB-6 Gas Discharge Tube (GDT) from RUILON is a high-reliability ceramic surge protection device designed to safeguard electronic systems from transient overvoltage events such as lightning strikes and switching surges. Featuring a 600V DC spark-over voltage, this component is optimized for high-voltage applications requiring stable, fast, and efficient surge suppression performance.
Built with advanced gas discharge technology, the 3R600TB-6 delivers 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 circuits. Its strong capability to withstand high impulse discharge current (8/20µs waveform) ensures reliable energy absorption and long operational life.
Compared to lower voltage variants, the 600V model provides enhanced resistance to false triggering in high-voltage environments while maintaining consistent and reliable protection performance. The compact 3RB-6 package supports efficient PCB layout and dependable operation in space-constrained applications.
This GDT is widely used in telecommunications equipment, power systems, industrial automation, signal line protection, and surge protection devices (SPD), delivering consistent and long-lasting circuit protection.
