In most power circuits, electronic components such as varistors are generally used, and there are many things that need to be paid attention to when using them, otherwise the varistors are still easily damaged...

The biggest feature of the varistor is that when the voltage applied to it is lower than its threshold "UN", the current flowing through it is extremely small, which is equivalent to a closed valve. When the voltage exceeds UN, its Resistance becomes smaller

When the varistor is working, each varistor unit is subjected to surge energy, and these varistor units are generally evenly distributed in the entire resistor body, that is, the entire resistor body is subjected to energy, rather than only the Zener diode regulator. The junction area withstands electrical power, which is why ceramic varistors have much larger current and energy ratings than Zener diode regulators. Its resistance value varies with the terminal voltage.
