The 2R350SK-5 SMD Gas Discharge Tube (GDT) from RUILON is a high-voltage surge protection device engineered to provide robust defense against transient overvoltage events such as lightning strikes and switching surges. Built using advanced ceramic gas discharge technology, this component ensures rapid transition from insulation to conduction, safely diverting high-energy surges away from sensitive electronic circuits.
With a nominal spark-over voltage of approximately 350V, the 2R350SK-5 is ideal for applications requiring higher voltage protection levels compared to lower-rated GDTs. It features high insulation resistance and ultra-low capacitance, making it especially suitable for high-frequency communication lines and precision electronic systems where signal integrity is critical.
The device supports high impulse discharge current capability (8/20 µs waveform) and offers excellent endurance under repeated surge conditions, ensuring long-term reliability. Its stable glow and arc voltage characteristics contribute to consistent performance even in harsh electrical environments.
The compact SMD package design allows seamless integration into modern PCB layouts and supports automated SMT assembly, reducing manufacturing complexity. Compared to lower voltage series, the 2R350SK-5 provides enhanced surge handling capacity and improved robustness, making it an ideal choice for industrial, telecom, and power protection applications.
