Transient voltage suppression (TVS) devices based on Metal Oxide Varistor (MOV) technology are commonly employed to safeguard electrical and electronic devices from excessive voltage risks. These risks could arise from sources like lightning-induced transients, static electricity, or similar hazards. MOV-based TVS devices possess a relatively high parasitic capacitance, which makes them suitable for use in low-frequency circuits, particularly AC utility power inputs. In these applications, they excel due to their ability to dissipate high amounts of power and exhibit clamping behavior. The high power dissipation capability of MOV-based TVS devices allows them to absorb and divert excess energy away from protected devices during transient events. This prevents the voltage from surpassing safe levels and potentially damaging the equipment. The clamping behavior of these devices ensures that even after a protection event, they continue to allow normal operation of the protected devices without the need for a reset process, as is typically required with crowbar protection mechanisms. MOV-based TVS devices are designed to respond rapidly to transient voltage surges, effectively limiting the voltage level and protecting downstream components. They achieve this by transitioning from a high-resistance state to a low-resistance state when subjected to excessive voltage. This characteristic enables the MOV-based TVS device to shunt the excess current away from sensitive components, diverting it to ground or other paths. These devices are commonly used in various applications, including power distribution systems, telecommunications networks, industrial equipment, and consumer electronics. Their ability to handle high surge currents and provide continuous protection without requiring manual intervention makes them a reliable choice for safeguarding electrical and electronic devices against transient voltage hazards. In summary, TVS devices based on Metal Oxide Varistor (MOV) technology offer effective protection against transient voltage surges. They excel in low-frequency circuits, such as AC utility power inputs, due to their high power dissipation capability and clamping behavior. MOV-based TVS devices rapidly respond to transient events, diverting excess energy away from protected devices and preventing voltage damage. Their reliable performance makes them widely used in various applications to ensure the safety and longevity of electrical and electronic equipment.
