Abstract
A varistor device includes a main body, a conductive area, a specific-melting-point metallic pin, and an elastic unit. The main body has a first surface, and the conductive area is located at the first surface. The specific-melting-point metallic pin has a first section and a second section. The first and the second sections are one-piece formed. The first section is fixedly disposed on the conductive area. The second section has a specific melting point such that the second section melts when a current flows between the first surface and the second section so as to expose the second section to a temperature greater than the specific melting point. The elastic unit has an end connected to the second section, and the elastic unit provides an elastic force to the second section to break the second section so as to cut off the current when the second section melts.
