TVS (Transient Voltage Suppressor) is an electronic component designed to protect an electrical circuit or system from high voltage transients, such as lightning or other high power pulses. It is usually a junction device, whose characteristics are such that when a certain pre-specified voltage is exceeded, a large current is conducted from the device, resulting in an interference that acts to protect the system or circuit from the transient in question.

The V39MT2B Varistor is a device of this type, specifically designed for protection against high voltage transients in power factor correction (PFC) applications. Composed of a multi-layered semiconductor material, the V39MT2B Varistor has a low VNDR, low thermal impedance and low noise characteristics. It also offers very high breakdown voltage and is capable of withstanding voltages up to 488V.

The primary application field of the V39MT2B Varistor is in power factor correction (PFC) applications, where it serves as the main protection device against high voltage transients. In such applications, the varistor\'s high voltage breakdown capability and fast response time make it extremely suitable for protecting sensitive electronic components like CPUs and memory modules.

When it comes to the working principle of the V39MT2B Varistor, it is based on its junction materials which have a voltage-dependent resistance. When a voltage above its rated value, or a transient of greater amplitude than its breakdown voltage, is applied across it, a large current flows through the device, creating a short interference that acts to reduce the applied voltage to a safe level.

In order to guarantee the device\'s proper protection capabilities, it is important to use the proper rating of the V39MT2B Varistor for each specific application. Generally, the device ratings should be chosen so that they are higher than the maximum system voltage that will be encountered. Furthermore, the ambient and operating temperature of the device should also be taken into account when determining the appropriate rating.

Sourced from quality materials, the V39MT2B Varistor offers a high quality protection solution for power factor correction applications, with low VNDR, low thermal impedance and low noise characteristics, and a fast response time.
