V180ZA10P application field and working principle

TVS - Varistors, MOVs are voltage-dependent, nonlinear devices, used primarily for protecting electrical systems against the effects of electrical transients. They use joule heating to absorb energy from the transient surge and disperses it in the form of heat. These devices employ a resistive material, sandwiched between two plates, that changes its electrical characteristics depending on the applied voltage - the higher the voltage, the lower the resistance.

Among the many types of varistors and MOVs available, the V180ZA10P is a very important type. It is suitable for a wide variety of applications, including automotive, industrial, medical, and telecommunication, among many others. The device features a wide operating voltage range − from 5.5 to 170 VDC. It can withstand up to 420 VDC maximum voltage without damage, while its capacitance range is 25 to 200 pF.

The V180ZA10P offers excellent protection against overvoltage and is specified with a highly reliable ABS/UL94V-0 plastic casing. It also has over-temperature shut-down protection and low leakage current. Thanks to its design, it can provide good protection against electric surges, such as those caused by EMI and ESD. As there is no clamp voltage at all applied voltages, the device makes an excellent choice for overvoltage protection.

The device works based on a simple principle: when an electrical surge is encountered, the resistive material inside the device heats up and its electrical characteristics change. This causes the resistance of the device to increase, which reduces the voltage across its leads. This process dissipates the energy of the surge in the form of heat instead of allowing it to continue through the circuit. The maximum voltage sustained by the device is 420 VDC.

In summary, the V180ZA10P is a voltage-dependent, nonlinear device suitable for use in many applications requiring protection from electric surges. It features a wide operating voltage range from 5.5 to 170 VDC, along with a maximum voltage of 420 VDC and a capacitance range of 25 to 200 pF. The resistive material heats up when a surge is encountered, causing the electrical characteristics of the device to change and reducing the voltage across its leads, thus dissipating the energy and providing excellent protection against overvoltage.
