3R150TD-8 150V Gas Discharge Tube (GDT) Surge Protector – 3RD-8 Package | RUILON

The 3R150TD-8 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. Featuring a 150V DC spark-over voltage, this component is optimized for low- to medium-voltage applications requiring stable and fast surge suppression performance.

Built with advanced gas discharge technology, the 3R150TD-8 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 signal lines. Its strong capability to withstand high impulse discharge current (8/20µs waveform) ensures efficient energy absorption and long operational life.

Compared to lower voltage variants, the 150V model provides a balanced protection level that reduces false triggering while maintaining fast and reliable surge response. The compact 3RD-8 package supports efficient PCB layout and dependable 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 long-lasting circuit protection.
