Transient voltage suppression (TVS) is a component used to protect sensitive electronics from voltage spikes caused by lightning, power outages, switching circuits and other signals. TVS devices are made up of varistors, MOVs, and other components. A varistor is a resistor with a large electric field that changes with an applied voltage. An MOV (Metal Oxide Varistor) is an electronic device that provides electrical protection against overvoltage when used with a series of components. MOVs have a low threshold voltage that increases as the amount of current is increased.

The B72207S0500K111 is a Metal Oxide Varistor (MOV) designed to protect circuits and components from transient overvoltage. It is a Motorized, non-polarized, low-leakage, non-linear device. It is available in different capacitances, ranging from 0.12 μF up to 2500 pF.

The B72207S0500K111 application field is in the DC and AC power line and equipment, such as surge protection for electrical machinery and electronics equipment, power down protection for TV, OA, communication, and industrial control projects. It also works well in automotive systems such as ECU, airbags, central control of locks and lighting.

The working principle of the B72207S0500K111 is to provide a low level of protection against transient overvoltages. The device is designed to operate below its rated voltage and must be connected in series with the line or component to be protected. When a transient voltage is applied, the MOV will draw excess current away from the protected circuits, dissipating it as heat in the MOV. Once the overvoltage event is over, the MOV will return to its normal operating state.

The B72207S0500K111 provides a simple, cost-effective solution for protecting sensitive electronic components such as semiconductors, MOSFETs and IGBTs from transient overvoltage conditions. This device has been designed and tested to provide reliable protection against surges and spikes up to 7kV, and is UL1449 approved. It is also RoHS compliant and eco-friendly, making it an excellent choice for projects where environmental impact needs to be considered.

In conclusion, the B72207S0500K111 MOV provides high performance protection from transient overvoltage conditions. This device is reliable and cost effective, making it an excellent choice in applications where overvoltage protection is needed.
