TVS varistors, also known as transient voltage suppressors, are electronic components used to limit the voltage to safe levels. These components provide over-voltage protection and are usually found in power supplies, voltage regulation systems, and other electronics applications.

MOVs (Metal Oxide Varistors) are similar to TVS Varistors in that they offer protection from overvoltage conditions; however, they differ in that they usually have faster response times and allow higher voltage levels before responding. MOVs are often found in power supplies, data communications, and automotive electronics applications.

TMOV34S391MP is a varistor designed to limit inrush current due to AC line cycling or unintended short circuit conditions in electronic systems. This device features low parasitic inductance, allows high current operation, and has a high response time for overvoltage protection. The device also features a high varistor voltage with low series resistance for robust circuit protection.

The TMOV34S391MP is typically used to protect automotive and consumer electronics against surge, overvoltage, and inrush current. This device is designed to be used in various applications such as DC power, AC mains, and data communication. It also offers surge protection up to 400 Vdc/780 Vac for up to 100 A peak current.

The working principles of the TMOV34S391MP are relatively simple. When a surge or overvoltage condition occurs, the device’s metal-oxide-varistor (MOV) material switches to a low-resistance state, allowing the surge current to be conducted to ground through the MOV. This reduces the voltage across the protected electronic components to a safe level so that they are protected from damage. The device resets itself once the overvoltage condition has dissipated. In this way, the TMOV34S391MP provides an effective and reliable means of protecting electronic components from surge and overvoltage conditions.

In conclusion, the TMOV34S391MP is an effective and reliable TVS Varistor and MOV device that offers overvoltage and inrush current protection for various electronic systems. This device features low parasitic inductance, high current operation, and fast response times for robust protection. Its simple working principles allow it to quickly and effectively reduce overvoltage and inrush current conditions to a safe level, protecting the electronic components from damage. This device is suitable for a wide variety of applications including automotive and consumer electronics, as well as power supplies, data communication, and AC mains.
