Abstract
A protection device comprises a first substrate, a second substrate, a fusible element and a heating element. The first substrate comprises a first surface, and the second substrate comprises a second surface facing the first surface. The fusible element is disposed on the first surface of the first substrate, and the heating element is disposed on the second surface of the second substrate and is disposed above the fusible element. When over-voltage or over-temperature occurs, the heating element heats up to blow the fusible element and thereby providing over-voltage and over-temperature protection.
