2R230SK-8 SMD Gas Discharge Tube 230V High Surge Current GDT Protector SMD Series | RUILON

The 2R230SK-8 SMD Gas Discharge Tube (GDT) from RUILON is a compact and highly reliable surge protection device designed to protect sensitive electronic circuits from transient overvoltage events such as lightning surges and switching spikes. Built with advanced ceramic gas discharge technology, this component provides rapid response by switching from a high-resistance state to a low-impedance conduction path, effectively diverting high-energy surges away from critical components.

With a nominal spark-over voltage of approximately 230V, the 2R230SK-8 is optimized for medium-voltage protection applications. It offers high insulation resistance and ultra-low capacitance, making it ideal for high-frequency communication lines and signal-sensitive circuits where maintaining signal integrity is essential.

The device is capable of handling high impulse discharge currents (8/20 µs waveform) and is engineered for long service life under repetitive surge conditions. Its stable glow and arc voltage characteristics ensure consistent performance even in harsh electrical environments.

The SMD package design allows for easy integration into compact PCB layouts and supports automated SMT manufacturing processes. Compared to lower voltage variants, the 2R230SK-8 provides improved surge endurance and reliability, making it suitable for telecom, industrial, and power protection applications.
