Abstract
A protection device comprises a first planar substrate, a second planar substrate, a heating element, a fusible element and an absorbent element. The first substrate comprises a first surface, and the second substrate comprises a second surface facing the first surface. The heating element is disposed on the first surface, and the fusible element is disposed above the heating element. The absorbent element is disposed on the second surface and above the fusible element. When over-current or over-temperature occurs, the heating element heats up to melt and blow the fusible element and the absorbent element absorbs melted metal of the fusible element.
