Introduction

Gas Discharge Tube Arresters (GDT), also known as Spark Gap Arresters or Gas Tube Switches, are devices used for over-voltage protection. GDTs are composed of three components: a gas-filled tube, a spark gap, and a series of resistors. In operation, an external voltage applied to the GDT triggers the spark gap, resulting in a spark across the gap. The spark then ionizes the gas within the tube, causing a temporary electrical circuit to be formed between the electrodes within the tube. This electrical circuit is designed to route excess voltage away from sensitive electronic components, protecting them from damage.

The Principles of GDT

The working principle of GDT is based on the process of gas discharge. The components necessary for this process include a gas-filled tube, a spark gap, and a series of resistors. When a voltage is applied to the GDT, the spark gap creates a spark which then ionizes the gas within the tube. This ionization process causes a temporary electrical circuit to be formed between the electrodes inside the tube. This circuit allows the excess voltage to be safely routed away from sensitive electrical components. The GDT works by redirecting excess voltage away from sensitive electrical components or circuit boards. When a voltage that is higher than the rated voltage of the component is applied, the spark gap opens and a spark is created between the electrodes. This spark ionizes the gas within the tube and creates a temporary electrical circuit between the electrodes. This circuit can dissipate the excess voltage, protecting the sensitive components from damage.

2035-28-SM-RPLF Application Field and Working Principle

The 2035-28-SM-RPLF is a Gas Discharge Tube Arrester specifically designed for use in high-voltage, high-frequency circuits. It is composed of a metal oxide gas-filled tube, a spark gap, and a series of resistors. The 2035-28-SM-RPLF is designed to protect circuit boards and components from electrical overvoltage conditions up to 20,000V. In operation, the 2035-28-SM-RPLF functions much like other GDTs. An external voltage applied to the arrester triggers the spark gap, which then ionizes the metal oxide gas within the tube. This ionization draws a current between the electrodes within the tube, creating a temporary electrical circuit. The resistors within the tube absorb the excess voltage and dissipate the energy, protecting the sensitive components and circuitry.
