The 3R150TA-6 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 provides a balanced protection level for low- to medium-voltage applications requiring stable and fast surge suppression performance.
Built with advanced gas discharge technology, the 3R150TA-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 signal lines. Its strong capability to withstand high impulse discharge current (8/20µs waveform) ensures efficient surge energy absorption and long service life.
Compared to lower voltage variants, the 150V model offers improved resistance to false triggering while maintaining fast and reliable protection performance, making it suitable for a wide range of electronic systems. The compact 3RA-6 package supports efficient PCB layout and dependable operation in space-constrained applications.
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.
