TVS (transient voltage suppressor) and varistors (voltage dependent resistor) are both types of overvoltage protection components, but with different characteristics. MOV (Metal Oxide Varistor) is the most popular type of varistor. The VM105MK122R040P120 is a Metal Oxide Varistor with excellent electrical parameters, making it an ideal product for protecting sensitive components from electrical surge and ESD.

Application Field

The VM105MK122R040P120 has many uses in various industries. It can be used in industrial, consumer electronics, and medical devices. It is used in power supplies to protect against overvoltage and lightning surges, automotive electronic systems, and consumer electronic systems including media players, GPS, tablets, and smart phones. In the medical industry, it is used to protect circuitry from electrical overloads. It is also used in other types of equipment including audio and video equipment, wind turbines, and LED lighting systems.

Working Principle

The VM105MK122R040P120 is a non-linear overvoltage protection device that works by absorbing electrical impulse energy. It works through a combination of the voltage-dependent resistor and voltage-clamping diode technologies. It is made up of two back-to-back Zener diodes, with each diode suppling a portion of the voltage protection. When an overvoltage occurs, current is limited by the varistor and the voltage is clamped to a safe level. The varistor works by providing a low-resistance path to limit or absorb the current. As the voltage increases, the resistance decreases and the current is limited.

The VM105MK122R040P120 is a small, easily integrated component that dissipates very little power and provides outstanding ESD and surge protection characteristics. It is also designed to operate reliably in a wide temperature range (-55°C to 125°C). Its small size, fast response time, and excellent immunability make it ideal for use in high-voltage applications.

Overall, the VM105MK122R040P120 is an excellent choice for a variety of applications. It is an ideal overvoltage protection device due to its fast response time, low power dissipation, wide temperature range, and excellent ESD and surge protection. It is easy to integrate, making it a great choice for a variety of projects.
