Abstract
A protection device comprises a first planar substrate, a second planar substrate, a heating element and a fusible element. The second planar substrate is attached to the underside of the first planar substrate to form a composite structure. The heating element comprises an insulating layer and a heating layer disposed thereon. The heating element is disposed on the first planar substrate, and the insulating layer is disposed between the first planar substrate and the heating layer. The fusible element is disposed above the heating element. The heating element heats up to blow the fusible element in the event of over-voltage or over-temperature.
