TVS - Varistors, MOVs

TVS-Varistors, MOVs (Metal Oxide Varistors) are components used to protect circuit boards from electrical surges. Often referred to as surge protectors, MOVs are semiconductor devices that generally absorb the electrical surge and clamp the voltage levels down in order to prevent damage to sensitive electronic components. MOV-07D781KTR is a specific type of MOV with a maximum voltage rating of 370V.

MOV-07D781KTR Application Field

MOV-07D781KTR is designed for use in many different types of electronic equipment, including computers and other home electronics. These types of MOVs have the highest performance in regards to power ratings; they are able to handle up to 781KV of surge current and provide effective protection for circuits. MOV-07D781KTR components are also used in a variety of portable electronic devices such as mobile phones, portable game systems, and remote control vehicles. The MOV-07D781KTR is designed to be utilized in a variety of situations, including those with high temperature and humidity. Its ability to withstand extreme temperatures is one of the biggest benefits associated with the MOV-07D781KTR, and its protective characteristics can be applied to a wide range of electronic devices.

MOV-07D781KTR Working Principle

When an excessive amount of voltage is applied to an electronic circuit, the MOV-07D781KTR typically absorbs the amount of voltage that exceeds the predetermined threshold. This is known as "clamping” and reduces the number of surges that could cause harm to sensitive electronic components. The MOV-07D781KTR conducts electricity in an unusual way. During normal operation, the MOV conducts little electricity until it reaches a specific threshold. At this point, a small gate opens, allowing the electron flow to continue. As the voltage increases, more of the gate opens and the electron flow increases. The gate closes only when the voltage drops below the predetermined threshold, preventing further damage. MOVs use a technology that is known as the “avalanche breakdown” effect. When the excess voltage reaches a certain point, the current path becomes unpredictable and current rushes through the MOV device, which limits the voltage to ensure that no damage occurs to sensitive electrical components. The MOV-07D781KTR is effective and reliable, and its protective capabilities can be used to safeguard a variety of electronic equipment. Due to its relatively low cost, the MOV-07D781KTR is used in many different applications, ranging from computers to small electronic gadgets. It is also easy to install and can significantly improve the safety and performance of any electronic device that it is used to protect.
