The 2R380SK-8 SMD Gas Discharge Tube (GDT) from RUILON is a high-voltage surge protection component engineered to protect electronic systems from transient overvoltage events such as lightning strikes, switching surges, and induced electrical spikes. Built using advanced ceramic gas discharge technology, this device provides ultra-fast switching by transitioning from a high-resistance state to a low-impedance conduction path when surge thresholds are exceeded.
With a nominal spark-over voltage of approximately 380V, the 2R380SK-8 is ideal for applications requiring elevated voltage protection levels compared to lower-rated GDT variants. It features high insulation resistance and ultra-low capacitance, ensuring minimal impact on high-frequency signal integrity, making it suitable for communication and data line protection.
Designed for high reliability, the device supports high impulse discharge current capability (8/20 µs waveform) and maintains stable performance under repeated surge exposure. Its controlled glow and arc voltage characteristics ensure consistent operation and extended service life in demanding electrical environments.
The compact SMD package design allows easy integration into space-constrained PCB layouts and supports automated SMT assembly processes. Compared to lower voltage GDTs, the 2R380SK-8 offers enhanced surge handling capability and improved durability, making it an excellent choice for industrial, telecom, and power protection applications.
