TVS - Varistors, MOVs are devices that are designed to protect electrical or electronic components from transients. They act as a protective shield against voltage surge or other high voltage stress, and can be used to protect any system that needs to sustain high voltage. VM105MK801R020P050 is a type of TVS - Varistor, MOVs typically used for automotive applications.

A Varistor, also known as MOV (Metal Oxide Varistor), is a semiconductor device that is used to absorb excessive voltage and dissipate it into the ground. The MOV acts as a resistor and absorbs high frequency electrical surges, thus maintaining the integrity of connected electronic systems and circuits. It can also protect systems from voltage spikes of up to 800V, which can cause damage to other components or circuitry. The VM105MK801R020P050 Varistor is an aluminum oxide based solid state device, and is generally used in automotive applications, although it can be used for other types of systems as well.

The VM105MK801R020P050 features a low breakdown voltage, which is typically in the range of 3.6V to 16V. It has a very low capacitance, which is typically 0.4µF, and a low leakage current of 1.5mA. It is very fast in responding to voltage surge, with a response time of a few microseconds. This makes this Varistor ideal for fast response applications, such as in automotive and photoelectric applications, where noise can potentially harm components. Additionally, the Varistor is also relatively tolerant to heat, and able to work in temperatures up to 125°C.

The working principle of the VM105MK801R020P050 Varistor is relatively simple. When a voltage waveform with an amplitude greater than the breakdown voltage reaches the recommended limit, the Varistor will immediately reduce its resistance and begin to protect the connected circuit. This is done by dissipating the energy of the voltage waveform, which effectively reduces the voltage of the waveform and prevents damage to the electronics. This is the same working principle that all other Varistors and MOVs use.

The VM105MK801R020P050 Varistor is often used in automotive and photoelectric applications, as mentioned earlier. In the automotive industry, Varistors are used to protect electronic control systems such as airbags or ABS systems. They are also used in brake systems, as they can absorb voltage spikes which can cause major damage to the brakes. For photoelectric applications, they are typically used to protect photo sensors from voltage surges caused by lightning strikes or power outages. Furthermore, they can protect other types of systems as well, such as aircraft, medical equipment and power supplies.

In conclusion, the VM105MK801R020P050 Varistor is a type of MOV (Metal Oxide Varistor) designed for automotive and other various applications. It has a low breakdown voltage, a low capacitance, and a low leakage current, making it ideal for fast response applications. Additionally, it has a working principle that is shared by other Varistors and MOVs, which is to absorb excessive voltage and dissipate it in the ground for protection. This Varistor is a valuable component for protecting connected circuitry or electronics from voltage surges, and can be found in many different applications.
