The protection function of a varistor can be repeated many times in most applications, but sometimes it is also made into a "one-off" protection device like a current fuse.

When the voltage applied to the varistor is lower than its threshold, the current flowing through it is extremely small, which is equivalent to a resistor with infinite resistance.

The response time of the varistor is ns, which is faster than the gas discharge tube and slightly slower than the TVS tube.
