A composite circuit protection device includes a positive temperature coefficient (PTC) component, a voltage-dependent resistor (VDR), and first and second conductive leads respectively bonded to the PTC component and the VDR. The PTC component includes a PTC layer having two opposite PTC surfaces, and first and second electrode layers each having an electrode surface which connects to and has an area smaller than that of a respective one of the PTC surfaces. The VDR includes a VDR layer having two opposite resistor surfaces, and third and fourth electrode layers each having an electrode surface which connects to and has an area smaller than that of a respective one of the resistor surfaces.
