The 2856692 application field and working principle of TVS - Varistors, MOVs include a variety of uses, from automotive and industrial applications to consumer electronics.

TVS - Varistors are a type of nonlinear resistor whose resistance changes with the applied voltage. Varistors are usually made up of a set of P-N junction layers connected together in parallel, with each layer exhibiting different resistance characteristics. When a voltage is applied to the P-N junctions, the resistance across them will decrease, forming a resistive path from the source to ground. The bridge-like characteristics of these components facilitate heavy duty current protection for circuits.

MOVs, or Metal Oxide Varistors, are a type of nonlinear resistor that varies in resistance depending on its applied voltage. Different from other varistors, MOVs use a special construction that allows them to become self-regulating and protect circuits from high surge current. By utilizing the principle of forward biasing, the electron movement inside the MOV’s will increase in response to an increase in voltage. This will create additional resistance, leading to an increase in energy dissipated and voltage decreased.

In automotive applications, MOVs are usually used as surge protectors on battery terminals and other electrical components exposed to static electricity, such as relays, switches, and lights. MOVs act as a fuse, absorbing a surge in current that otherwise may damage the other components. Industrial and power lines also take advantage of MOVs protection, as their self-regulating construction makes them ideal for protecting expensive equipment from surges.

MOVs are also popular in consumer electronics. They are used to protect sensitive semiconductor components from voltage spikes that may occur during times of heavy electrical usage. By locating the MOV near the power input of a device, we can ensure that a surge in power does not damage the device. With increasing concern over the lasting power of consumer electronics, manufacturers are now recommending the use of MOVs in their products.

In conclusion, the 2856692 application field and working principles of TVS - Varistors, MOVs covers a wide range of applications and are now essential for modern electronics. As our reliance on sensitive electronics grows, the use of these varistors is becoming increasingly important to protect valuable equipment, both in commercial and consumer fields.
