Transient Voltage Suppression (TVS) products based on Metal Oxide Varistor (MOV) technology are used to protect electrical and electronic equipment from the harmful effects of overvoltage, such as those from lightning, static electricity, or other similar transients. These products have relatively high parasitic capacitance, making them suitable for low-frequency circuits, such as AC mains power inputs. However, their high power dissipation and clamping characteristics make them excel in this type of circuit protection, ensuring normal operation of the equipment without the need for resetting after a protection event.
