TVSs (Transient Voltage Suppressors) and MOVs (Metal Oxide Varistors) are two types of Varistors that are commonly used in electrical circuits in order to protect sensitive components from unexpected spikes and dips in the voltage. The VDRH14V250TLE is a type of Varistor that is used specifically in automotive applications. This article will discuss the application field and working principle of the VDRH14V250TLE.

Application Field

The VDRH14V250TLE is a specialized type of Varistor that is designed to be used in high-performance, electric vehicles and other electrical and automotive applications. It provides surge protection to the vehicle’s various electrical systems, including the fuel system, starter system, lighting system, brakes and suspension system, and other components that can be adversely affected by unexpected voltage spikes and dips. It also helps reduce the risk of short-circuiting or other damage to the vehicle’s electrical systems.

This type of Varistor is resistant to high temperatures and can handle up to 250 volts of peak impulse voltage, making it suitable for a variety of automotive applications. Additionally, it is very reliable and is able to withstand typical environmental fluctuations, such as extreme temperatures, moisture, and salt fog.

Working Principle

The VDRH14V250TLE works by clamping the incoming voltage by diverting any excessive electricity away from the vulnerable devices. It does this by utilizing a junction diode that is connected in parallel to the varistor. The junction diode helps to limit the maximum voltage that is applied to the component being protected. This helps to protect the device and prevent it from experiencing any unexpected voltage surges that can damage the component or even cause a fire. When a voltage surge is detected, the Varistor switches to a low resistance state, which effectively shunts the excessive voltage away from the device.

The Varistor is also equipped with a built-in thermal protection device, which helps to prevent it from overheating due to excessive current. The thermal protection device can detect any changes in temperature and will automatically shut off the connection if the temperature reaches a certain threshold. This helps to ensure that the Varistor doesn\'t overheat, which can potentially damage vulnerable components or even cause a fire.

Overall, the VDRH14V250TLE is an ideal Varistor for electrical or automotive applications. It helps to protect vulnerable components from damage due to unexpected voltage spikes and dips, and its thermal protection device ensures that the Varistor does not overheat. This makes it the perfect choice for high-performance, electric vehicles and other electrical and automotive applications.
