SMD Metal Oxide Varistor High Transient Current Capability Low Leakage Current​

Varistor is the abbreviation of Voltage Sensitive Resistor, which is a kind of nonlinear resistance element. The resistance of the varistor is related to the voltage applied at both ends. When the voltage applied to the varistor is within its nominal value, the resistance of the resistor is infinite, and almost no current flows. When the voltage across the varistor is slightly greater than the nominal voltage, the varistor quickly breaks down and conducts, and its resistance drops quickly, making the resistor in a conducting state. When the voltage decreases below the nominal voltage, its resistance starts to increase again, and the varistor returns to a high resistance state. When the voltage across the varistor exceeds its maximum limit voltage, it will break down completely and cannot recover by itself.

Varistors are characterized by high performance and low price, small size, wide operating voltage range, fast response to overvoltage pulses, strong impulse current resistance, small leakage current (less than a few microamps to tens of microamps), and temperature coefficient of resistance. It is an ideal protection component and is widely used in home appliances and other electronic products. It is often used to form overvoltage protection circuits, noise elimination circuits, spark elimination circuits, lightning protection circuits, and surge voltage circuits. Absorbing circuits and protecting semiconductor components.
