The 3R150B-5S Gas Discharge Tube (GDT) from RUILON is a compact and high-reliability ceramic surge protection device designed to protect electronic circuits from transient overvoltage events such as lightning strikes and switching surges. With a 150V DC spark-over voltage, this component provides an optimal balance between fast response and stable protection for low- to medium-voltage applications.
Engineered with advanced gas discharge technology, the 3R150B-5S 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) enables effective surge absorption and long service life.
Compared to lower voltage GDT variants, the 150V model reduces the risk of nuisance triggering while maintaining reliable surge protection, making it suitable for a wide range of electronic systems. The compact 3RB-5S package supports efficient PCB design and dependable performance 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.
