TVS - Varistors, MOVs

The V18ZU40PX10 is a metal oxide varistor (MOV) application field and it is widely used in a variety of devices that need surge protection. MOVs are voltage-dependent devices and they work by providing a low-impedance path to ground when the voltage across the MOV exceeds its designed trip voltage. The MOV functions as a switch that allows the current to be shunted away from the protected component to ground, reducing the probability of any damage.

Varistors, or varistor devices, are effectively two-terminal, non-linear, voltage-dependent resistors. They work by diverting or shunting the surge current away from vulnerable system components to the ground. They are reactive components that respond to changes in their environment, including changes in the applied supply voltage.

The V18ZU40PX10 varistor has a high level of sensitivity to incoming surges, with a fast response time to protect against transients as short as 20 nano-seconds. It has a flat variable voltage, and a 19mm disc form factor to fit most surge protection applications. It also has an ultra low leakage current.

One major advantage of the V18ZU40PX10 is that it has a very high working voltage, meaning it is able to protect circuits against very high voltages without needing much current to do so. On the other side, its low impedance allows it to respond quickly and effectively to transients. It also has an excellent ability for load current handling.

The V18ZU40PX10 has an operating temperature range of -40 to +85 degrees Celsius and can withstand up to 2,280 AC V peak. It is also RoHS compliant, halogen-free and UL rated.

The V18ZU40PX10 is suitable for a wide range of applications, such as AC/DC mixing power, industrial base power supplies, telecom power supplies, LED lighting applications and monitor adapters. It is also suitable for use in mobile phones, laptops, tablets and other portable electronics.

In summary, the V18ZU40PX10 is an excellent metal oxide varistor for use in surge protection applications. It is highly sensitive to incoming surges, has a high working voltage and a low impedance, which makes it fast and effective at diverting transients away from circuits and components. Additionally, its excellent load current handling capabilities and wide operating temperature range make it ideal for protecting a variety of AC/DC mixing power, industrial base power supplies, telecom power supplies, LED lighting and other applications.
