AVR-M2012C120MT6AB is an advanced varistor device specially designed for protecting circuits from transient overvoltages in power lines. It is usually used in the environment of medium voltage application. A varistor is also known as a voltage-dependent resistor (VDR) designed to protect systems from overvoltage transients. Such devices provide a very high resistance in normal working conditions, and in an overvoltage situation will switch to a very low resistance in order to discharge and dissipate the transient energy.

The AVR-M2012C120MT6AB is a type of Transient Voltage Suppressing(TVS) devices, specifically a Metal Oxide Varistor (MOV), which consists of a metal oxide film formed between two electrodes. The MOVs protects against over voltages by quickly clamping the voltage across its terminals to a safe level. When a sufficient voltage is applied across an MOV, the metal oxide film acts like a rectifier or diode-like structure, allowing a free passage of electrons from the N+electrode to the P– electrodes and effectively reducing the voltage across the terminals.

The AVR-M2012C120MT6AB is specifically designed for low-leakage applications, as well as the protection of low-overvoltages; it has a special type of freeze mode which ensures that if an overvoltage occurs, the dielectric will enter to a low-leakage state in order to maintain the protection, while also maintaining safe operation. Additionally, it has very low clamping voltage compared to other similar devices, which reduces the total power dissipation. The protection voltage is 20V, and the rated current is 6A.

In terms of applications, the AVR-M2012C120MT6AB varistor is often used in lightning protection circuits, power switching circuits, and high-voltage input circuits, where it provides high-power switching without excessive transient voltage overshoot or dV/dt overshoot. Additionally, it can also be used for EMC suppression purposes, where it can effectively reduce EMI and ESD emissions. The device is also suitable for connecting between data lines and system power connections, as it provides good ESD protection at these points.

The AVR-M2012C120MT6AB is a low-cost and highly-efficient TVS which offers superior protection from transient overvoltages in power lines. It is a dependable and cost-effective solution for medium voltage applications, and its special features make it an ideal choice for a wide variety of applications. Its high-quality and durable construction ensure long-lasting performance and trouble-free operation, making it a reliable investment for any application.
