A varistor, also known as a voltage-dependent resistor (VDR), is a non-linear electronic component used for protecting circuits from transient voltage spikes. They are commonly used as surge protection devices in low-voltage circuits. The VE2220K801R075 is a varistor designed for use in low voltage applications such as lighting dimmer circuits and other sensitive components.

The VE2220K801R075 is built with a silicone-coated zinc oxide (ZnO) material, which provides excellent performance in transient voltage suppressor (TVS) applications. The materials utilized in the construction of this varistor provide a very low current leakage, allowing it to effectively protect sensitive circuits against transient overvoltage. It also features a highly reliable and thermally stable dielectric layer that helps protect against thermal transients and breakdowns.

This varistor offers a wide working voltage range of 22 to 38 VDC, which is suitable for a variety of low voltage applications. It provides a peak-to-peak energy rating of 0.75 Joules and a maximum clamping voltage of 790 Joules. The VE2220K801R075 also features a very low tolerance for voltage transients, which makes it ideal for use in sensitive circuitry.

The working principle of the VE2220K801R075 is based on the concept of a voltage-dependent resistor (VDR). When a voltage spike or transient occurs in a circuit, the varistor will absorb the energy and limit the voltage rise. This helps protect sensitive components from damage and prevents a larger voltage spike from occurring.

The VE2220K801R075 provides an excellent alternative to traditional surge suppression methods, such as the use of gas tube arresters. It is smaller in size and requires less space, allowing for easier installation. It is also more reliable and offers better protection against transients than gas tube arresters.

The VE2220K801R075 is well-suited for use in many low voltage applications, such as lighting dimmers and other electronic circuits. It is an excellent choice for providing effective protection against transient voltage spikes, while remaining small and economical.
