TVS - Varistors, MOVs, also known as Transient Voltage Suppression (TVS) devices, are specialized electronic components that protect against transient overvoltage conditions. They are commonly used to protect delicate electronic equipment from damage due to power surges, spikes, and other transient voltage phenomena. MOVs, or Metal Oxide Varistors, are the most common type of TVS device, and are renowned for their excellent surge protection capabilities. VDRH07K250TSE is a type of varistor that is widely used in these applications.

VDRH07K250TSE Application Field

The VDRH07K250TSE is a popular MOV based TVS device, and is designed to protect sensitive electronic equipment from transient overvoltage surges of up to 250V peak. It is constructed with a metal oxide semiconductor material and has a bidirectional breakdown characteristic. It is typically used in a variety of applications, including power supply units, automotive electronics, audio/video equipment, and a variety of computer and communications systems.

VDRH07K250TSE Working Principle

The VDRH07K250TSE is an example of a bidirectional or symmetrical varistor. It consists of two electrodes, similar to those that can be found in a regular diode. The device is designed to perform two functions: to block current flow from one side to the other in the presence of overload voltages, and to reduce the instantaneous peaks of the overvoltage before it reaches the unprotected component. When a voltage surge occurs, the electrodes of the varistor become forward-biased, and the device provides a low-impedance path for the surge current. This reduces the amount of voltage across the load, preventing it from being damaged. Over time, the varistor will return to its normal state, and can be used over and over again.

In addition to surge protection, the VDRH07K250TSE can also reduce the level of conducted and radiated electrical noise, thus improving the overall performance of any system it is used in. It also acts as an absorber of electromagnetic interference (EMI) and radio frequency interference (RFI), making it a great choice for protecting components from both radiative and electrically coupled noise.

Conclusion

The VDRH07K250TSE metal oxide varistor is a popular TVS device that is used to provide transient overvoltage protection in many types of electronic equipment. It is a bidirectional or symmetrical device, meaning it can be used to protect both positive and negative voltage surges. It is also an effective absorber of electromagnetic interference and radio frequency interference, and can reduce the level of conducted and radiated noise.
