2R380SK-5 SMD Gas Discharge Tube 380V High Surge Protection GDT SMD Series | RUILON

RUILON

The 2R380SK-5 SMD Gas Discharge Tube (GDT) from RUILON is a high-voltage surge protection component designed to deliver reliable defense against transient overvoltage events such as lightning strikes and switching surges. Utilizing advanced ceramic gas discharge technology, this device ensures rapid activation under surge conditions, safely diverting excessive energy away from sensitive electronic circuits.

With a nominal spark-over voltage of approximately 380V, the 2R380SK-5 is ideal for applications requiring higher voltage thresholds compared to lower-rated GDT devices. It features high insulation resistance and ultra-low capacitance, making it suitable for high-frequency communication and signal lines where minimal interference is critical.

Engineered for durability, the component 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 operation and extended service life in demanding environments.

The compact SMD package allows for efficient PCB integration and supports automated SMT assembly, enabling modern, space-constrained designs. Compared to lower voltage GDTs, the 2R380SK-5 provides enhanced surge handling and improved robustness, making it an excellent choice for industrial, telecom, and power protection applications.
