SL1011A250C

Gas Discharge Tube Arresters (GDT) are devices that are designed to protect sensitive electrical systems by limiting high voltage exposure from surges or other transient events. The SL1011A250C product in this family is designed to limit high voltage transients to 250 volts. The product is a silica based tube with a built in resistor between the cathode and anode which is specialized for use in sensitive electronic circuits.

The SL1011A250C component is designed to absorb energy from voltage or current transients and dissipate it in a controlled manner by initiating a spark within the device. The component creates an electrical barrier to limit voltage from the application to a predetermined level. This process is known as “tripping” and occurs when the voltage exceeds the predetermined level. Once tripped, the device should remain in a non-conductive state until the power is reset. The component can reset itself in the absence of a reset pulse.

The SL1011A250C is suitable for use in surge protection circuits, overvoltage protection, and single transient protection networks. These components are commonly used in power supplies, test equipment, communications equipment, computer circuits, machine tools, and other equipment where sensitive electronics are the primary concern. The components are manufactured with a wide range of ratings, including 250 volts.

The SL1011A250C product is constructed from a cylindrical, non-reactive, silica-based material which acts as an insulator. The product has anode and cathode wires that are in contact with electrodes at opposite ends of the device. When current flow increases, the resistance between the two wires increases, resulting in an electrical arc across the gap between them. This arc acts as a spark gap, interrupting the flow of current and protecting the equipment from excessive voltage.

The device has two distinct working modes. The first mode of operation is high voltage-clamping mode and the second mode is shunting mode. In high voltage-clamping mode, the SL1011A250C component actively clamps the surge voltage to a predetermined level and dissipates the excess energy. In shunting mode, the device functions as a shunt resistor, allowing the peak surge current to bypass the protected circuit. This mode of operation is especially useful in single-transient protection networks, such as those used in power supplies.

The SL1011A250C also has a built-in resistor which helps to protect the device from damage caused by high surge currents or temperatures. This makes the component suitable for use in a variety of environments including extreme temperatures. The resistor also acts as a protective filter, absorbing any noise that is generated by the device.

In summary, the SL1011A250C is a specialized gas discharge tube arrester that is designed to protect sensitive electronics and other equipment from current and voltage surges. It will actively clamp the surge voltage to its predetermined level and dissipate the excess energy. It is suitable for use in high voltage-clamping mode and shunting mode in a number of applications. Additionally, the device has a built-in resistor which provides additional protection from temperature and noise.
