Gas Discharge Tube Arresters (GDT) are devices that are used to protect electronic circuits from transient voltage spikes. The CG2470SN is one of the most popular GDTs used in the industry today. In this article, we will take a look at the application fields and working principle of the CG2470SN.

Application of CG2470SN

The CG2470SN is used in a variety of applications, including automotive, industrial, telecommunications, and military. In the automotive industry, the CG2470SN is used for protection from electrical noise, surges, and voltage transients. In the industrial sector, the GDT is used to protect circuit boards from high-voltage transients and lightning strikes. Telecommunications systems also rely on the CG2470SN for protection from electrical transients. And in the military, the device is used to protect vital equipment from sudden electrical spikes.

Working Principle of CG2470SN

The CG2470SN is a highly efficient device that is designed to protect sensitive circuits from sudden electrical surges. It works by using a two-stage arcing mechanism to ground out the surge current before it can damage or overload the protected circuit. The first stage of the arcing mechanism is a fast transient voltage suppressor (TVS). The TVS is designed to reduce the peak voltage level of the surge quickly and efficiently. This prevents most of the damaging voltage from traveling through the protected circuit.

The second stage of the arcing mechanism is the gas discharge tube (GDT). The GDT acts as a spark gap and is designed to dissipate the excess voltage and current present in a surge. The GDT is filled with a short-lived gas that ionizes when exposed to a high voltage. This ionization of the gas creates a spark, which then accelerates the arc discharge. This arc discharge then safely carries the surge current to ground, thus preventing it from damaging the protected circuitry.

Once the surge is over, the gas discharge tube begins to cool, and the short-lived gas recombines to form an inert gas that no longer conducts electricity. This ensures that the GDT will not short out any circuits or cause interference after the surge has passed. It also prevents any voltage or current surges from occurring again.

Conclusion

The CG2470SN is a reliable and efficient device that is used in a variety of applications to protect sensitive circuits from transient voltage spikes. Its two-stage arcing mechanism provides excellent protection from both high voltages and currents. With its robust design and superior performance, the CG2470SN has earned its place as one of the most popular GDTs used in the industry today.
