The 2R450SK-5 SMD Gas Discharge Tube (GDT) from RUILON is a high-voltage surge protection component designed to safeguard sensitive electronic systems from transient overvoltage events such as lightning strikes, switching surges, and induced electrical disturbances. Utilizing advanced ceramic gas discharge technology, this device provides rapid switching by transitioning from a high-resistance state to a low-impedance conduction path when voltage thresholds are exceeded, ensuring efficient surge diversion.
With a nominal spark-over voltage of approximately 450V, the 2R450SK-5 is ideal for applications requiring elevated voltage protection levels. Compared to lower-rated GDT devices, it offers improved surge endurance and higher energy handling capability, making it suitable for demanding industrial and power line environments. The device also features high insulation resistance and ultra-low capacitance, ensuring minimal impact on high-frequency signal integrity.
Engineered for reliability, the component supports high impulse discharge current capability (8/20 µs waveform) and performs consistently under repetitive surge conditions. Its stable glow and arc voltage characteristics contribute to long operational life and dependable protection performance.
The compact SMD package design allows seamless PCB integration and supports automated SMT assembly, making it ideal for modern compact electronics requiring efficient and durable surge protection.
