2R300SK-5 SMD Gas Discharge Tube 300V Surge Protector High Energy GDT SMD Series | RUILON

RUILON

The 2R300SK-5 SMD Gas Discharge Tube (GDT) from RUILON is a high-voltage surge protection component designed to deliver superior performance in protecting electronic systems from transient overvoltage events. Utilizing advanced ceramic gas discharge technology, this device provides rapid switching under surge conditions, effectively diverting high-energy pulses away from sensitive circuitry.

With a nominal spark-over voltage of approximately 300V, the 2R300SK-5 is well-suited for applications requiring higher operating voltage margins. It offers excellent insulation resistance and ultra-low capacitance, ensuring minimal interference with high-speed signal transmission. This makes it ideal for communication lines, industrial interfaces, and precision electronic systems.

Engineered for durability, the device can withstand high impulse discharge currents (8/20 µs waveform) and repeated surge exposure without degradation, ensuring long service life. Its stable glow and arc voltage characteristics further enhance reliability in harsh electrical environments.

The compact SMD package allows easy integration into modern PCB layouts and supports automated assembly processes. Compared to lower voltage GDT variants, the 2R300SK-5 provides enhanced surge handling capability and improved robustness, making it a preferred solution for demanding protection applications.

Overall, the 2R300SK-5 combines high energy absorption, fast response, and compact design to ensure reliable circuit protection.
