TVS (transient voltage suppression) diodes, or MOVs (metal oxide varistors) are devices that are used to protect electronic circuits from high-voltage or surge transients. The MOV-20D271KTR is a MOV that can provide effective protection against voltage surges and power disturbances, as well as reducing the risk of apparatus failure and delays in data transmission. This device is a 20mm radial-lead metal-oxide varistor with an AC and DC breakdown voltage of 220V and a peak current of 27 Amps.

The MOV-20D271KTR can be applied in a broad range of applications to provide protection against transient voltage surges. These application fields include: industrial, automotive, consumer electronics, telecom, LED devices, and power systems. Additionally, it can be applied in a wide range of devices including power supplies, communication systems, circuit boards, lighting fixtures, DC motors, cables, home appliances, and computer hardware.

The MET-20D271KTR is a non-linear semiconductor device that works to protect against transient or high-voltage surges. The device is based on the relatively simple and predictable non-linear electrical behavior of the zinc-oxide crystal. When a voltage higher than the breakdown voltage is applied to the MOV, it acts to clamp the voltage to a safe level, effectively protecting the device. This works by creating a short across the source voltage or current through the metal-oxide junction of the device.

The MOV\'s resistance changes in proportion to the applied voltage, and it takes charge from the voltage surge. This is called its "dynamic resistance", and the MOV will dissipate the energy absorbed from the transient voltage in the form of heat. The device also has a current limiting feature which works by limiting the current through the MOV, again protecting the circuit.

The MOV-20D271KTR offers a number of advantages compared to other surge protection devices, including the ability to dissipate relatively high levels of energy in short times with low internal losses, and the ability to effectively protect against transient voltage surges without requiring any external components.

The MOV-20D271KTR is an ideal device for protecting electronic circuits from transient voltage surges. Its wide range of application fields, broad range of devices and applications, and simple, predictable non-linear behavior make it an effective solution for surge protection. Its high-energy dissipation capacity, low internal losses, and lack of external components required for protection make it an attractive option for a variety of protection needs.
