What is V82ZA2PX1347

V82ZA2PX1347 Varistor is a small electrical component used to protect electronic circuits from a variety of transient over-voltages. They are available in a variety of sizes and voltages, and are most commonly used as protection against excess voltage or transients in power supply, telephone lines, cable TV lines and computer peripherals. Varistors are robust, reliable and have a low failure rate.

Application Fields of V82ZA2PX1347

Varistors such as V82ZA2PX1347 find their most common application in surge protection. Surge protection is required for lightning strikes and other electromechanical events which can cause instantaneous bursts of voltage that can damage or destroy unprotected devices. Varistors are also used to protect electronic circuits from over-voltage which may cause the circuit to fail by exceeding its maximum voltage tolerance. Varistors may also be used in applications where an over-voltage condition may occur, such as battery chargers or power supplies.

Working Principle of V82ZA2PX1347

Varistors such as V82ZA2PX1347 work by diverting or limiting the magnitude of transient voltages and currents. A varistor is a two-terminal, non-linear component. When the voltage across it exceeds a certain break-over voltage, it undergoes a dramatic change in resistance. This creates an extremely low impedance path for the transient current, which is "shorted" out safely. This means that any excess voltage is diverted away from sensitive components.

Varistors provide circuit protection by limiting the peak voltages and currents transmitted to the protected circuit. This is done by providing a fast "clamping" action to the circuit, where the voltage is limited to a safe level. Varistors are also used in switching power supplies to move the AC line voltage away from a critical value where the supply may be operating in an unstable or out-of-regulation mode.

Conclusion

V82ZA2PX1347 Varistor is a small electrical component mainly used in surge protection. Its working principle is to divert or limit the magnitude of transient voltages and currents. It provides circuit protection by limiting the peak voltages and currents transmitted to the protected circuit. Its application field spreads widely from battery chargers to power supplies, and it is a robust and reliable electronic component.
