Voltage-dependent resistors, also known as surge protectors, are electronic components used to protect sensitive devices from damage due to overvoltage and to limit or absorb transient spikes in voltages. The V470ZT05PX1347 is an example of a voltage-dependent resistor, more specifically a Metal-Oxide Varistor (MOV).

The V470ZT05PX1347 is primarily designed for transient overvoltage protection. It is a radial leaded 20mm (lead diameter 5mm) Disc Ceramic Element with a Metal Oxide Varistor (MOV) element. The working voltage range is 6V to 450V, with a varistor voltage (V_1mA) of 350V, and a leakage current of 0.1mA (at 275V). The V470ZT05PX1347 has a clamping (let-through) voltage of less than 100V. The rated energy is 25 Joules and the maximum peak current is 3.0kA.

The MOV device is a ceramic disc containing a mixture of metal oxides that produce a voltage-dependent resistor. The material acts as an electrical insulator up to a certain voltage, at which point it changes to a conductor. This change in conductivity occurs as a result of increased electron movement caused by an increase in voltage. The decrease or increase in the resistance of the device occurs almost instantaneously, allowing the current to be blocked or diverted. This action is considered to be a nonlinear and non-symmetric response.

Due to its low residue current, low clamping voltage, and high surge current capability, the V470ZT05PX1347 is widely used in electronic equipment. It is commonly used in power supplies, motors, welding equipment, and entertainment equipment to provide overvoltage protection. It can also be used in other devices such as light fixtures, sensors, and telecommunication systems.

The V470ZT05PX1347 is designed to absorb large transient surges in voltage by providing a path for the current to flow. A large current surge is observed when there is a fault in the system or if it is subjected to the impact of a nearby lightning strike. The V470ZT05PX1347 is designed to reduce the magnitude of the voltage spike, thereby protecting the other components in the circuit from damage or destruction.

In summary, the V470ZT05PX1347 is an example of a voltage-dependent resistor (MOV) designed primarily for transient overvoltage protection. It is commonly used in power supplies, motors, welding equipment, and entertainment equipment, as well as light fixtures, sensors, and telecommunication systems to provide overvoltage protection. With its low residue current, low clamping voltage, and high surge current capability, the V470ZT05PX1347 is an ideal solution for protecting vulnerable devices from overvoltage.
