The 2R350SK-8 SMD Gas Discharge Tube (GDT) from RUILON is a high-voltage surge protection device designed to deliver reliable performance in protecting sensitive electronic systems from transient overvoltage events such as lightning strikes and switching surges. Utilizing advanced ceramic gas discharge technology, this component ensures rapid switching from a high-resistance state to a low-impedance conduction path, effectively diverting high-energy surges away from critical circuitry.
With a nominal spark-over voltage of approximately 350V, the 2R350SK-8 is ideal for applications requiring higher voltage thresholds compared to lower-rated GDT devices. It features high insulation resistance and ultra-low capacitance, ensuring minimal signal interference in high-frequency communication and data transmission lines.
Engineered for durability, the device supports high impulse discharge current capability (8/20 µs waveform) and maintains stable performance under repetitive surge exposure. Its controlled glow and arc voltage characteristics ensure consistent and reliable operation in harsh electrical environments.
The compact SMD package design allows seamless integration into modern PCB layouts and supports automated SMT assembly processes. Compared to lower voltage variants, the 2R350SK-8 provides enhanced surge handling capability and improved robustness, making it an excellent choice for telecom, industrial, and power protection applications.
