The 3RS-6×8 series is a high-power, three-electrode surface-mount gas discharge tube designed for common-mode surge protection in high-energy differential systems. This series offers multiple DC breakdown voltage ranges from 75V to 600V with a ±20% tolerance. Its 1kV/μs impulse spark overvoltage range is 600V to 1400V, ensuring high-precision common-mode triggering protection. The device features ultra-low inter-electrode capacitance of ≤1pF, ensuring the integrity of high-speed differential signal transmissions such as Gigabit Ethernet, while maintaining a high insulation resistance of ≥10GΩ to control leakage current. The three-electrode architecture supports line-line-ground coordinated operation and can repeatedly withstand 10kA common-mode surge currents with 8/20μs waveforms and 10A discharge capability at 50Hz AC.
It complies with the ITU-T K.12 standard and provides symmetrical suppression performance. Operating temperature ranges from -40°C to +90°C, it is primarily used for primary protection of 5G base station main circuits, core ports of industrial Ethernet switches, CATV backbone equipment, and high-power power systems. The 3RS-6×8 series adopts a 6mm × 8.2mm enhanced surface mount package.
