Abstract
A circuit protection device including a PTC device and a diode. A first insulation layer is formed between first electrode surfaces of the diode and the PTC device. Vias for thermally and electrically connecting the first electrode surfaces of the diode and the PTC device are formed in the first insulation layer. First, second, and third external electrode pads are provided on a second insulation layer formed on the second electrode surface of the PTC device. The second electrode surface of the PTC device is electrically connected to the first external electrode pad. The first electrode surface of the diode and the first electrode surface of the PTC device are electrically connected to the second external electrode pad. A second electrode surface of the diode is electrically connected to the third external electrode pad.
