TVS (Transient Voltage Suppressors), MOVs (Metal Oxide Varistors) and VE2220K122R014 are devices designed to protect electronic equipment from the harmful effects of overvoltage transients. They are the cornerstone of any overvoltage protection design.

TVS devices protect sensitive electronics from electrical overstress caused by voltage transients, such as those caused by a lightning strike or power surge, by absorbing their energy. They provide a fast reaction time and high surge capability, while also offering low capacitance and low residual voltage.

MOVs (Metal Oxide Varistors) on the other hand absorb voltages that are triggered by system faults or rapid changes of current on the power supply line. MOVs overcurrent protection works by diverting excess current to a low resistance circuit while limiting the voltage. This allows the circuit to continue functioning without creating a hazardous situation.

VE2220K122R014, is a particular type of varistor designed to protect sensitive electronic components from overvoltage transients. It is a high reliability bidirectional TVS diode built on a silicon gate chip designed to meet specific requirements.

The principle of operation of VE2220K122R014 is based on the breakdown voltage of the device. When subjected to an overvoltage transient, the device conducts the surge current and thus provides a short- circuit path which limits the voltage across the protected components. If the device is subjected to a reverse voltage, it acts as a diode, allowing the current to flow in the opposite direction. The device remains unbiased until a specified voltage is reached, at which point it conducts current.

VE2220K122R014 is particularly suitable for application in automotive electronics, communications and consumer electronics. It also finds use in computers, home appliances and many other products and applications. The device works by diverting the overvoltage to ground before it can cause any damage to the electronics.

In a nutshell, VE2220K122R014 is a type of transient voltage suppressor or MOV device which is designed to limit the voltage that flows through electronic components. The device breaks down when a certain overvoltage transient is applied, providing a short circuit path to limit the voltage across the load. It is highly reliable and well suited for many applications in automotive, consumer and computer electronics.
