Gas Discharge Tube arresters (GDT) are protective devices used to divert potentially hazardous surge currents that otherwise can damage electrical systems. Since their introduction in the early 1900s, GDT arresters have been an integral component in the protection of electrical circuits, especially in areas where lightning protection is important.

The 2052-40-SM-RPLF arrester is a very popular Application Specific Integrated Circuit (ASIC) type of GDT that offers a longer operating life and higher performance than other arrester types. It is ideal for use in power supplies, telecommunications systems, and any other application where a reliable and efficient protection against electrostatic discharge or lightning strike is required. The arrester is designed to provide an efficient solution for dissipating electrical energy in a determined manner, allowing minimal disruption to the system.

The 2052-40-SM-RPLF arrester features a unique four-electrode design that dissipates energy from both the primary and secondary electrodes simultaneously for maximum protection. This combination of current and voltage monitoring allows the arrester to support a wide range of applications, including lightning protection, lightning arresters, transient voltage surge suppression, and vertical line protection.

The 2052-40-SM-RPLF arrester is able to effectively protect connected electronic components from surge currents up to 10.0A peak, 10/160µs wave, or 6.0A/μs repetitive. It is able to respond in less than 25 nsec, and its high frequency/voltage rating allows it to be used in high duty applications. The arrester is also extremely resistant to surge currents, withstanding up to 10kA 8/20µs wave and 1000V/μs voltage surge.

The 2052-40-SM-RPLF arrester works by detecting an overvoltage condition and, in response, short-circuiting the input signal to ground by extending the anode gap. The anode gap is designed to respond to overvoltage events faster than a traditional system would take to respond, drastically reducing the time taken to protect the system and the attached components.

When the arrester is exposed to an overvoltage condition, the anode gap is increased in length via an internal mechanism, which creates a voltage drop along the gap. This drop in voltage causes the arrester to essentially short-circuit the input signal, effectively stopping any overvoltage from reaching the circuitry and components of the system. After the overvoltage is handled, the anode gap shrinks back to its original length.

The 2052-40-SM-RPLF arrester is a reliable, efficient, and durable GDT device that is suitable for a variety of high-energy applications. Its unique four-electrode design allows for a higher surge capacity than other arrester types, and its higher frequency/voltage rating makes it suitable for applications where extreme electrical surges are expected. It is also able to respond quickly and effectively to overvoltage conditions, providing maximum protection to the system and connected components.
