Abstract
A reflowable thermal fuse includes a positive-temperature-coefficient (PTC) device that defines a first end and a second end, a conduction element that defines a first end and a second end in electrical communication with the second end of the PTC device, and a restraining element that defines a first end in electrical communication with the first end of the PTC device and a second end, in electrical communication with a second end of the conduction element. The restraining element is adapted to prevent the conduction element from coming out of electrical communication with the PTC device in an installation state of the thermal fuse. During a fault condition, heat applied to the thermal fuse diverts current flowing between the first end of the PTC device and the second end of the conduction element to the restraining element, causing the restraining element to release the conduction element and activate the fuse.
