SMD4042-230E 230V Gas Discharge Tube – SMD4042 Package | RUILON

RUILON

The SMD4042-230E Gas Discharge Tube (GDT) from RUILON is a high-reliability ceramic surge protection device designed to safeguard electronic circuits from transient overvoltage events. Utilizing advanced gas discharge technology, it delivers rapid response to lightning strikes, switching surges, and electrostatic discharge (ESD), ensuring consistent and long-term circuit protection.

With a DC spark-over voltage of 230V, this component is well-suited for medium-voltage applications, offering a balanced protection threshold between low and high-voltage GDT series. It ensures reliable triggering without premature activation, making it ideal for protecting sensitive electronics. The device supports high impulse discharge current (8/20µs) and features excellent impulse spark-over characteristics (1kV/µs), enabling dependable performance in harsh electrical environments.

Its low capacitance at 1 MHz helps maintain signal integrity in high-speed communication lines, while high insulation resistance minimizes leakage current and improves efficiency. Stable glow voltage and arc voltage characteristics contribute to extended service life and consistent operation.

Housed in a compact SMD4042 package, the SMD4042-230E allows easy surface-mount integration and flexible PCB layouts. It is widely used in telecommunications systems, industrial equipment, power supplies, smart meters, and consumer electronics, delivering robust surge protection and enhanced system reliability.
