A TVS (transient voltage suppressor), MOV (metal oxide varistor) or varistor is a component that is designed to protect electrical/electronic circuits from voltage transients. The V751HC32 is a common type of varistor designed for specific application fields and encompasses specific working principles.

Application fields

The V751HC32 is a varistor used in a wide range of electronic and electrical systems. It is particularly popular for applications involving high-power electrical components such as electric motors, air conditioners, and refrigerators. It is also used to protect electronic circuits from voltage transients. Protection of data lines, DC power supplies, data processing and communication equipment is another common application field where the V751HC32 is used.

The V751HC32 is used in the medical industry, thanks to its high level of protection. In particular, it is well-suited for MRI and X-ray machines, as the device can protect the power supplies of these machines from unexpected voltage fluctuations.

Working principle

The V751HC32 is a type of varistor which protects electrical/electronic circuits from voltage transients. It works by providing a low impedance path to absorb the surge energy. This in turn limits the voltage spike to ensure that the components are not damaged.

The device operates by using zinc oxide blocks as a voltage-dependent resistor, or VDR. The VDRs are connected in series, in a manner similar to a voltage divider. This allows the device to monitor the input voltage, and if it deviates from the desired level, the VDRs will reduce the voltage spike.

The V751HC32 is designed to have a ‘fail safe’ operation, meaning that it will not allow a voltage spike to pass through the device if the voltage exceeds the specified level. This is a safety feature that helps protect the components that the device is protecting. Additionally, the device is designed so that it is self-restoring, meaning that it will reset after a transient has been absorbed. This ensures that the device will continue to provide protection even after a transient has been absorbed.

Conclusion

The V751HC32 is a commonly used type of varistor which is widely used in a range of electronic and electrical applications. It has a specific application field and works by providing a low impedance path to absorb surge energy and limit voltage spikes. It is also designed for fail-safe operation and is self-restoring after a transient has been absorbed.
