Varistors, also known as voltage-dependent resistors (VDRs), are two-terminal nonlinear electronic components with a voltage-dependent resistance. This type of component is made of metal oxide with a wide range of resistance values from 0.1 megohm to 10 gigohm and a breakdown voltage of up to 6000V. The V270ZT05PX1347 is an example of such a component.

The V270ZT05PX1347 is a radial lead varistor with a high current capability and an operating voltage of 270V ACrms and a maximum surge current of 3850A. It has a maximum energy absorption of 10kJ and a pulse current capability of up to 15kA. It is also designed to operate within a wide temperature range of -40°C to +85°C. The lead diameter is 0.6mm and the lead length is 17.3mm.

The V270ZT05PX1347 is primarily used in AC power supplies for overvoltage protection, as well as for surge protection in telecoms and signal line communication systems. It is well suited for line-to-ground protection applications such as lightning surge, ring wave, and ESD protection. The device can also be used for filtering out high frequency noise, power conditioning, and other high-temperature applications in electronic components.

The working principle of the V270ZT05PX1347 is based on its nonlinear voltage-dependent resistance. This type of component behaves like a variable resistor, where the resistance changes with the applied voltage. When the applied voltage is below the breakdown voltage, the resistance is very high, but as the voltage increases beyond the breakdown voltage the resistance decreases exponentially. This property is useful in applications such as protection circuits, where the device can limit the voltage to a safe level by absorbing excess energy.

The V270ZT05PX1347 is a versatile and robust varistor designed to provide protection from electrical over-voltage in various types of AC power supplies and telecoms systems. Its high current and surge capabilities along with its wide temperature range makes it ideal for a wide range of applications from power conditioning to overvoltage protection.
