A varistor, or voltage dependent resistance (VDR) is a semiconductor device that has a large non-linear change in its electric conductance when subjected to a corresponding change in voltage. In the VDRH14V275BKE, the voltage breakdown is achieved at 275 volts with an energy rating of 4 Joules. VDRH14V275BKE is often used because of its simplicity and low cost.

The working principle of VDRH14V275BKE can be explained in three steps. When the voltage across the device is below its peak breakdown voltage, the device exhibits a low, almost constant resistance. As the voltage increases, the resistivity of the device will increase at a faster rate. At the point of peak breakdown, the resistivity of the device will quickly drop to near zero. Finally, as the voltage is increased beyond the peak breakdown point, the device will exhibit a high level of resistance.

VDRH14V275BKE is widely used in various applications such as signal protection, energy absorption, snubber circuits, UPS systems, motor protectors, and surge protectors. Its peak breakdown voltage of 275V and energy rating of 4 Joules allows it to dissipate the surge energy quickly, thus offering excellent surge current protection. In addition, the fast response time of VDRH14V275BKE makes it suitable for use in UPS systems, motor protectors and snubber circuits.

VDRH14V275BKE can also be used in other applications such as automotive applications, light emitting diode (LED) lighting, solar panel protection, industrial equipment, home appliances and others. In these applications, VDRH14V275BKE can protect sensitive electronic components from overvoltage surges due to lightning and other power spikes. The device also helps to maintain stable output voltage and current levels in time-sensitive applications.

To ensure optimal performance, it is important to choose the right device for the application. It is recommended to select a VDRH14V275BKE device with a voltage rating that is equal to or higher than the peak operating voltage of the application. The device should also have an energy rating that is sufficient for the application. Lastly, it is important to read the device datasheet and select the right device for the application.
