Since the 19th century, electricity has been studied and used by people for various energy applications. The use of electricity has come along with great advances in technology and with it, dangerous side effects like power surges and spikes which can damage electronic equipment and can even cause outages or fire. In order to protect against such high voltage occurrences, Gas Discharge Tube Arresters (GDTs) are employed.

GDTs are also referred to as Surge Arresters, Surge Suppressors, Surge Protectors, or Lightning Arresters, and are designed to protect valuable electronic circuitry from the impact of electrical power surge. GDTs are placed between the power source and protected components to absorb most of the energy from lightning strikes and other electrical surges and provide a low resistance path for the power to flow safely back to the source. This prevents excessive current or spikes of voltage from damaging any of the connected equipment.

The 2026-47-C2LF application field and working principle are as follows. The 2026-47-C2LF is part of the C2 series of GDTs from Littlefuse, delivered in a cylindrical package with 11 PIN connections.

The 2026-47-C2LF can be used for various lightning-protection applications, such as protecting telecom equipment, computers, video and security systems, and much more.The 2026-47-C2LF has a maximum voltage rating of 600V AC, a maximum let-through voltage of 9V, and a maximum surge current rating of 50A. It also has an internal diode to shunt any high voltage or current away from sensitive electronic components.

The 2026-47-C2LF works by absorbing the energy produced by a surge in current or voltage. When a surge of power is detected, the gas in the GDT ionizes, creating a conductive path for the current or voltage to flow safely to the power source. This ionized gas dissipates the electricity, preventing any further damage to the electronics.

The 2026-47-C2LF also offers protection to connected equipment from reverse voltage, ESD, and overvoltage surges. It utilizes gas filled chambers to clamp down very quickly and successfully on any incoming surges, protecting the equipment from the damage associated with them. It is also certified to UL1449 and CSA223.4-02, ensuring a high level of reliability and performance.

In conclusion, the 2026-47-C2LF GDT provides reliable, effective protection from voltage and current surges and lightning strikes. By absorbing the energy from these surges, it can prevent damage to sensitive electronic equipment, and also provide necessary protection for reverse polarity, ESD and overvoltage conditions.
