TVS - Varistors, MOVs, are surge protection devices, used to protect electronic devices against voltage transients, or surges, caused by events such as lightning strikes or accidental contact with higher voltage lines.

The V14H320AUTO is one type of TVS devices, which is a three-phase bi-directional Silicon-Avalanche Diode (SAD) Transient Voltage Suppressor (TVS). It has multiple applications mainly used for common mode and differential mode surge protection. This device is designed for the protection of heavy-duty industrial equipment against inductive surge over-voltages.

Typically, the V14H320AUTO provides superior protection against common mode surges, including surges caused by lightning strikes and other transient voltage events. It provides fast response to transient over-voltage and low leakage current. Moreover, the device can effectively protect circuits against electrical switching transients, such as those encountered in motor control and power supplies.

The V14H320AUTO acts as a bidirectional arrangement when used to protect against common mode surges. In this type of application, two V14H320AUTO devices are arranged with their anodes connected in opposite polarity. This creates a bridge configuration in which one device protects the positive side of the circuit and the other protects the negative side. In this way, both positive and negative surges are handled equally.

The V14H320AUTO also provides differential mode protection against surge transients. When used in this type of application, two V14H320AUTO devices are connected in parallel on the same side of the circuit, with their anodes and cathodes connected in opposite polarity. This arrangement provides protection to the entire circuit against both positive and negative differential mode surges.

The working principle of the V14H320AUTO is as follows. When exposed to a surge, the device is able to absorb the electrical current. This causes the device to develop a voltage drop, which in turn limits the surge current so that it cannot damage the protected devices. After the surge has passed, the device is able to return to its normal operating state.

The V14H320AUTO is an ideal device for a variety of applications, such as industrial electronics, motor control, power supplies, and other high-voltage applications. It offers the highest level of protection from sudden voltage transients and can handle high current levels for extended periods of time without damage.
