varastorisia

Varastorisia, also known as varistor, is a type of electronic component that is designed to protect other components in an electrical circuit from voltage spikes and surges. It is a type of nonlinear resistor that exhibits a high resistance to low voltages and a low resistance to high voltages. This property makes it an effective component for protecting sensitive electronic devices from transient voltage surges, which can cause damage or failure.

Varastorisia are typically made from zinc oxide (ZnO) or silicon carbide (SiC) and are available in various sizes and voltage ratings. They are often used in power supplies, motor control circuits, and other applications where protection against voltage spikes is crucial. Varastorisia are characterized by their voltage-current (V-I) characteristics, which show a sharp increase in current at a specific voltage level, known as the breakdown voltage.

The primary function of a varastor is to clamp the voltage across the protected circuit to a safe level during a transient event. When a voltage surge occurs, the varastor conducts and diverts the excess current, preventing it from reaching the protected components. After the surge has passed, the varastor returns to its high resistance state, allowing normal operation to resume.

Varastorisia are widely used in various industries, including telecommunications, automotive, and industrial electronics, due to their reliability and effectiveness in protecting sensitive equipment. They are an essential component in ensuring the longevity and performance of electronic systems by providing robust protection against voltage transients.
