TVS (Transient Voltage Suppressor) diodes are used in the design of electrical and electronic circuits for the purpose of protecting sensitive components from over-voltage transients. The MOV (Metal-Oxide Varistor) is one of the most common and popular types of TVS devices. The MOV-20D270KTR is a surface-mount technology (SMT) metal-oxide varistor which is used for providing protection from over-voltage transients.

The MOV-20D270KTR has a working voltage range of 7-27V, an energy rating specification of 20J, and a peak pulse current of up to 200A. The device is capable of withstanding up to 275V of reverse transients. Its high peak pulse power and current capability makes it ideal for High Voltage (HV) applications like surge protection.

The MOV-20D270KTR is most commonly used in energy and/or signal circuits to protect both sensitive components and equipment from high-voltage transients. It can also be used in power systems for other applications such as overvoltage protection, under-voltage protection, and over-current protection. The device is designed to absorb excessive energy generated by transient overvoltage and overcurrent events, thus preventing surges from damaging sensitive equipment.

The MOV-20D270KTR works on the principle of nonlinear conductance, meaning its resistance changes with voltage. The device works by allowing a small amount of current to pass through under normal operating conditions. When the current increases due to a surge or transient, the resistance of the device increases, thus limiting the amount of energy that passes though. This reduction in current limits the level of voltage seen by the connected components or circuits.

In summary, the MOV-20D270KTR is a surface-mount technology metal-oxide varistor which is most commonly used for providing over-voltage protection to energy and/or signal circuits. It is designed to absorb excessive energy generated by transient overvoltage and current events, preventing surges from damaging sensitive components. The device works by limiting the amount of current passing through it as the voltage level increases, thus reducing the level of voltage seen by the connected circuits.
