Gas Discharge Tube Arresters (GDT) are electrical protective devices that help protect electronic equipment from lightning lightning strikes and other transient overvoltage faults. GDTs are specifically used to limit or suppress voltage of both high-energy lightning impulse and low-energy surges. GTCS26-351M-R05-2 is a Double Trisil Surge Suppressor GDT specifically designed to limit or suppress transient voltage. This article will look at the application field and working principle of GTCS26-351M-R05-2.

GTCS26-351M-R05-2 Double Trisil Surge Suppressor GDT is used in communication, instrumentation, power, protection system, telecommunications, medical electronic equipment and industrial automation equipment with a rated working voltage of up to 30V DC or above. It is usually installed in a DC circuit and can protect two lines. This GDT device has a UL94-V0 flame retardant and 2.45mm pitch insulation spacing structure, making it well suited for a variety of applications. In addition, GTCS26-351M-R05-2 has passed UL certification and can be used outdoors.

As for the working principle of GTCS26-351M-R05-2, the device consists of two Trisil chips and a gas discharge tube. When the normal working voltage is lower than the nominal voltage of the device, the elecric energy of the system is favorable, so no current will pass through the GDT. When the peak voltage reaches the rated voltage of the GDT, the gas discharge tube will discharge the current and form a low internal resistance path. This process will limit the peaks of the current, thus protecting the circuit and other devices from damage.

When the peak voltage exceeds the rated voltage of the GDT, the Trisil will start conduction at the same time. Since there is a reverse voltage increase during the discharge of the GDT, the Trisil is used to further reduce the reverse voltage and protect the circuit. After the peak voltage cancels out, the Trisil will be cut off and no current will pass through the GDT.

In conclusion, GTCS26-351M-R05-2 is a Double Trisil surge suppressor GDT used in a variety of applications that can effectively protect the circuit and other devices from damage due to lightning surges or other transients. The device is comprised of two Trisil chips and a gas discharge tube. When the peak voltage reaches the rated voltage of the GDT, it will be triggered and the Trisil will be activated to limit the peak voltage, thereby protecting the circuits and other components.
