MOV-07D820KTR, a silicon-carbide based Thyristor Voltage Surge Suppressor (TVS), is a component designed for overvoltage transient protection of electronic devices. It is used to protect devices against voltage transients caused by lightning, electrical noise, and switching loads. The MOV-07D820KTR is classified as a TVS- Varistor, MOV (Metal Oxide Varistor) and has been specifically designed for applications requiring high energy containment in a small form factor.

The MOV-07D820KTR has its own specific application fields, including protection of power lines against overvoltage transients generated by lightning, and its very small size helps in saving board space.

The device has two main functions: a capacitive element and a varistor element. The capacitive element is designed to reduce the voltage applied to the device while the varistor element is used to shunt most of the current away from the protected device. This helps to reduce the stress on the protected device and ensure its proper working condition.

The MOV-07D820KTR also incorporates voltage-dependent resistors (VDRs), which are designed to provide overvoltage protection for sensitive electronic components. VDRs also help in clamping any high voltage transients before they reach the protected device, thereby preventing any damage to the device.

The MOV-07D820KTR is based on the working principle of a Thyristor Voltage Surge Suppressor, which employs a solid-state switch to clamp the voltage transients in a very short amount of time.

When an overvoltage is detected, the thyristor switches from the OFF state to the ON state, providing a very fast response for overvoltage protection, while the MOV-07D820KTR also has a built-in thermal shutdown circuit which will stop the device from functioning when temperatures become excessively high or if the current exceeds its rated limit. This prevents any permanent damage from occurring.

The MOV-07D820KTR is ideal for applications that require high energy containment, and is thus deployed in a wide range of applications, including telecommunication, data communication, computer peripherals, office equipment, consumer electronics, medical equipment and automotive. It is also designed to protect against ESD, EFT, power supply transients, and inductive explosions.
