The 3R070TB-6 Gas Discharge Tube (GDT) from RUILON is a compact ceramic surge protection device designed to protect sensitive electronic circuits from transient overvoltage events such as lightning strikes and switching surges. Featuring a 70V DC spark-over voltage, this component is ideal for low-voltage applications requiring fast response and precise surge suppression.
Built with advanced gas discharge technology, the 3R070TB-6 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 high-speed communication and data lines. Its strong capability to withstand high impulse discharge current (8/20µs waveform) ensures effective surge absorption and long operational life.
Compared to higher voltage variants, the 70V model enables early triggering for rapid protection of sensitive circuits against transient surges. The compact 3RB-6 package supports efficient PCB layout and reliable operation in space-constrained applications.
This GDT is widely used in telecommunications equipment, signal line protection, consumer electronics, industrial automation systems, and surge protection devices (SPD), delivering consistent and dependable circuit protection.
