SMD4042-1000E 1000V Gas Discharge Tube – SMD4042 Package | RUILON
RUILON
The SMD4042-1000E Gas Discharge Tube (GDT) from RUILON is a high-voltage ceramic surge protection device specifically engineered to protect electronic circuits from extreme transient overvoltage conditions. Utilizing advanced gas discharge technology, it provides ultra-fast response to lightning strikes, switching surges, and electrostatic discharge (ESD), ensuring reliable and long-term system protection.
With a DC spark-over voltage of 1000V, this device is ideal for high-voltage and heavy-duty applications where maximum surge tolerance and operational stability are critical. Compared to lower-voltage GDT series, it significantly reduces the risk of false triggering while maintaining powerful surge suppression capability. The component supports high impulse discharge current (8/20µs) and features excellent impulse spark-over performance (1kV/µs), making it suitable for harsh and high-energy environments.
The device offers low capacitance at 1 MHz, preserving signal integrity in sensitive communication lines, along with high insulation resistance to minimize leakage current. Stable glow voltage and arc voltage characteristics ensure consistent operation and extended service life.
Encased in a compact SMD4042 package, the SMD4042-1000E allows easy surface-mount integration and flexible PCB design. It is widely used in telecommunications infrastructure, industrial systems, power equipment, smart grid applications, and consumer electronics, delivering superior surge protection and enhanced reliability.
