TVS - Varistors, MOVs, have many application fields, such as noise and pulse protection, overvoltage protection, and lightning protection. VDRH07K320BKE is one of the most popular TVS protection devices used for these purposes. This article will explore the application field and working principle of the VDRH07K320BKE.

The VDRH07K320BKE is a Transient Voltage Suppression (TVS) diode device, primarily used for suppressing transients caused by lightning, electrical transients, power cross, and inductive loads. It utilizes Metal-Oxide Varistor (MOV) technology to offer superior surge protection performance. This MOV component features a low, medium, and high clamp voltage of 7V, 13.6V, and 20V respectively. The VDRH07K320BKE also features a built-in snubber network, which ensures that the peak current is limited to a safe level for the MOV.

The VDRH07K320BKE is used in a wide range of applications, from automotive electronics to consumer electronics and industrial devices. It is often used in the protection of data lines and signal lines, as it is able to handle transients up to an energy rating of 28 joules. The device is also widely used in several modern mobile applications such as handsets and tablets, to protect them from the damages that can be caused by lightning and other transient events.

The working principle of the VDRH07K320BKE is rather simple. When a transient or surge occurs, the voltage increases rapidly, causing the resistance of the MOV to decrease. This reduces the voltage across the device, clamping it at the MOV’s clamp voltage level. The snubber network ensures that the current is limited and the MOV is not damaged. When the transient has passed, the MOV’s resistance returns to normal, allowing the voltage across the device to return to the normal level.

In summary, the VDRH07K320BKE is a well-known and widely used MOV device for various protection applications. It offers superior surge and transient protection performance, and is designed to handle transients up to 28 joules of energy. The device is used in a wide variety of applications, from consumer electronics to automotive and industrial applications. The basic working principle of the device is quite simple, with the resistance of the MOV varying in response to transient events, thus protecting the device from any damage.
