The 3R150B-5SS Gas Discharge Tube (GDT) from RUILON is a high-reliability ceramic surge protection device designed to safeguard electronic circuits from transient overvoltage events such as lightning strikes and switching surges. Featuring 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-5SS 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 absorption and long service life.
Compared to lower voltage GDT variants, the 150V model reduces nuisance triggering while maintaining reliable and fast surge suppression, making it suitable for a wide range of electronic systems. The compact 3RB-5SS package supports efficient PCB layout and dependable operation in space-constrained designs.
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.
