A varistor, also known as a voltage-dependent resistor (VDR), is a general-purpose electrical component which has a nonlinear, asymmetric voltage-current characteristic. TVS devices are one type of varistor that offer protection against high-voltage electrical surges. They utilize a varistor material, often zinc oxide (ZnO), in combination with a low-temperature oxide (LTO) or strontium titanate (STO) varistor dielectric. A MOV (metal oxide varistor) is another type of varistor which works in similar fashion, however, those are typically considered to be more reliable, in particular for higher-voltage applications.

The 2381 5740 10803 three-terminal varistor device from Schurter is one example of a TVS. This particular model is designed for applications up to 8 kV peak surge voltage and is available with standard test ratings from 5 to 25 A. It provides a high-performance, non-linear AC transient voltage surge device for protection of electronic circuits from transient voltage events. It is used to protect equipment from over voltage transients and other phenomena such as lightning strikes, inductive switching transients, and motor switching transients.

The 2381 574 10803 is constructed of high purity, non-conductive electrophoresis zinc oxide (ZnO) and low temperature solder (LTO). The dielectric is encapsulated in environmentally safe silicone rubber making it tolerant to a wide range of environmental conditions. The device employs a 3-terminal (T3) structure and a silicon-oxide-nitride-oxide-silicon (SONOS) technology to offer peak surge capability and high dv/dt immunity. It also has a wide operating temperature range of -40°C to +140°C.

The working principle of the 2381 574 10803 is relatively simple. When an AC voltage applied to the T3 terminals exceeds the varistor\'s critical voltage, the ZnO and LTO materials create a nonlinear voltage-current characteristic which limits and absorbs transient voltage events. This works by creating a narrow voltage gap in the ZnO material which reduces the current flow between the positive and negative terminals. The SONOS structure also helps to reduce the possibility of overvoltage and the build-up of electric charge, thus providing long-term protection against extreme voltage events.

In conclusion, the 2381 574 10803 varistor from Schurter is a highly versatile device which is used for protecting sensitive electronic equipment and circuits from transient voltage events. It is constructed with a ZnO and LTO dielectric, and utilizes the SONOS technology in order to provide excellent protection against overvoltage events. It is suitable for a wide range of applications, and can be used in a range of temperature environments.
