TVS - Varistors, MOVs are two of the commonly used surge protection components in the market. VDRS05C060BSE are one of the latest varieties of these components and are used for high current surge protection in applications such as switching power supplies, air conditioners, computers, and more. In this article, we will discuss the application fields and working principle of VDRS05C060BSE.

Application Fields of VDRS05C060BSE

VDRS05C060BSE is a surface mount type varistor designed for high current surge protection. It is generally used to protect sensitive electronic components from overvoltage surges that can result from lightning strikes, line switching, and so on. This type of varistor is also widely used in overcharge protection circuits, where it can limit the maximum voltage applied to a charger or other electrical device. The device also finds application in switch mode power supplies as a means of limiting the voltage that can be applied to the power stage.

Due to its robust design, VDRS05C060BSE is also suitable for other harsh environment applications, such as automotive, railway, and aerospace. It is widely used in EMC (electromagnetic compatibility) applications where it can reduce electromagnetic interference by providing a low impedance path for high frequency signals.

Working Principle of VDRS05C060BSE

The working principle of VDRS05C060BSE is the same as any other varistor. When the voltage applied to the device exceeds its rated voltage, or a certain value called the trip point, the device starts conducting. This conductivity is due to the presence of a special non-linear material inside the device. This material allows the current to flow between the two electrodes of the varistor and reduces the overvoltage to a safe level. The current carrying capacity of the varistor is rated in amperes (A) and it should be selected carefully according to the current requirements of the device it is used with.

The varistor is usually designed as either a surface mount type or a through-hole type device. They are usually covered with a heat-resistant encapsulation to protect the internal components from external environmental effects. Additionally, some SPIAs (surface-mount high-voltage non-linear devices) incorporate a thermal protection mechanism that limits the power dissipation of the varistor and helps to ensure safe operation.

Conclusion

In conclusion, VDRS05C060BSE is a surface mount type varistor that is designed for high current surge protection. This type of device is suitable for applications such as switching power supplies, air conditioners, computers, and more. Working principle of VDRS05C060BSE is same as any other varistor – when the voltage applied to the device exceeds its rated voltage, or a certain value called the trip point, the device starts conducting.
