Varistors, also known as voltage-dependent varistors (VDVs), are two-terminal nonlinear electronic components in which the current varies as the applied voltage varies. They are primarily used in the protection of circuits against voltage transients or surges in industrial, automotive and consumer electronics. MOVs (Metal Oxides Varistors) are a type of varistor used in applications requiring high power capabilities and high surge ratings. The V10E625 is a MOV designed for the purpose of providing an effective solution to transient over-voltage problems that occur in industrial, commercial and residential applications.

The V10E625 is a commercial bidirectional device with a peak pulse power rating of 10,000 watts (10 kw). It is designed to protect against transient voltage surges up to an amplitude of 530 volts and a duration of 5 microseconds. The device is offered in an axial leaded, disc-shaped package. The mounting method is through-hole and the device can be mounted on either printed circuit boards (PCB) or through-hole components.

The V10E625 provides an economical and reliable solution to transient over-voltage problems. It is constructed with two sets of parallel electrodes – the positive and negative electrodes – which are made of a zinc oxide material. The zinc oxide material is preferred because it has a high dielectric breakdown strength and a low dielectric absorption ratio. These characteristics enable the device to dissipate voltage surges quickly and efficiently, thereby protecting against surges of up to 530 volts.

The device is also designed to withstand high operating temperatures and is rated for a maximum operating temperature of 175-degrees Celsius. Additionally, it has a soft switching characteristic, which allows it to withstand transient current pulses without producing an over-voltage condition.

The device is designed to operate in both AC and DC circuits. It can be used for applications such as over-voltage protection for generators, power supplies and surge protectors. It can also be used for the protection of electronic controllers, drives and motors from overvoltage transients. Additionally, it can be used as an EMI filter to reduce Common Mode pulsed power noise or radio frequency interference (RFI).

The working principle of the V10E625 MOV is fairly simple. When the MOV is exposed to a transient voltage surge, the zinc oxide elements in the MOV are compressed. This reduces the amount of current that can flow through the MOV and dissipates the energy resulting from the surge.

The V10E625 is an ideal solution for those seeking to protect against voltage transients in industrial, commercial and residential applications. It is an affordable and reliable solution that can dissipate voltage surges quickly and efficiently. Its soft switching characteristic allows it to withstand transients without causing an overvoltage condition, making it an excellent choice for a variety of applications.
