ERZ-E11A681

ERZ-E11A681 is a type of TVS - Varistors, MOVs. It can provide overvoltage protection and transient surge protection, usually by channeling the electrical current away from sensitive components into the ground. This article will discuss the application field and working principle of ERZ-E11A681.

Application Field

ERZ-E11A681 is a high voltage Varistors which can be widely used in various applications, such as automobiles, computer, telecommunications, shipbuilding, power transmission and distribution systems, as well as medical devices. It plays an important role in protecting electrical circuits from transients caused by lightning strikes or power supply spikes.The applications ERZ-E11A681 covered generally include the external power supply modules of new energy vehicles, electronic control units, driver controllers, braking electronic control units, electronic control modules, fuel pump controller, front and rear turn signal controllers, etc.

Working Principle

ERZ-E11A681 is a Metal Oxide Varistor which includes two electrodes and a dielectric layer. When the voltage applied to the electrodes is smaller than the breakdown voltage of the dielectric layer, the varistor is in the OFF state. Once the applied voltage is equal to or exceeding the breakdown voltage, the varistor will turn ON and begin to conduct current.When the overvoltage condition occurs, the varistor will clamp the voltage to the rated clamp voltage. As the applied voltage increases, the current increases exponentially through the varistor until the maximum current rating is reached, at which point the varistor will trip and will no longer allow significant current to pass through it.In addition to protecting sensitive electrical components, the ERZ-E11A681 Varistor can also decrease power dissipation by utilizing its low impedance during peak surge events. This in turn reduces the amount of heat generated on the electrical components and increases their lifespan.
