TVS-Varistors, MOVs are well known for its ability to discharge high fault currents by providing temporary lower voltage levels, a surge arrester often placed at the beginning of a cable may protect the application from dangerous transients, making it a popular choice for areas that are susceptible to transient voltages. The ERZ-E08B751CS is a Varistor that is particularly suitable for these applications where larger transients are expected.

The ERZ-E08B751CS Varistor has an excellent clamping capability for high single peak and repetitive surge currents and is also designed to suppress surge transients up to 8kV (8/20us, 10/1000us). It has a voltage rating of 6V-9V DC and is used in many sectors, from telecommunications and data transmission to automotive and consumer electronics applications.

The ERZ-E08B751CS Varistor is a metal-oxide varistor (MOV) which works on the principle of voltage dependent resistance. This means that the resistance of the varistor decreases with increase in voltage, when the varistor is exposed to a voltage that is higher than its rated voltage it quickly reduces its resistance to almost zero and becomes practically a short-circuit - the current is discharged and the source voltage is clamped. This reduces the transient voltage to a safe level before it enters the circuit.

The Varistor works with high efficiency and with very little delay (sub-nanosecond) and has a wide range of operational temperature and can withstand both AC and DC transients. The Varistor also has a low thermal resistance for reliable performance and a very low clamping voltage of 8V (8/20us, 10/1000us) making it very efficient for high peak current applications. It also exhibits very low leakage current when tested under maximum voltage conditions, thus resulting in low self-heating and providing enhanced protection to the circuit.

The Varistor is encapsulated with an epoxy resin and thus is highly durable and resistant to temperature, shock and vibration, thus making it a suitable choice for many harsh environment applications. It also features a wide working frequency range of 6.5MHz-70MHz, making it suitable for a range of radiofrequency applications. The mechanical size and lead length of the Varistor is in accordance with the lead-free requirements making it RoHS compliant.

The ERZ-E08B751CS is a versatile Varistor and is suitable for a wide range of application fields and hence has become quite popular, from high-voltage power supplies and data-lines to AC and DC motor controls, UPS, industrial and electronic equipments. It is hence a very attractive solution for high-surge applications and is suitable for its use in areas that are prone to transients.
