Summary:Disclosed is a composite electric circuit protection device including a positive temperature coefficient (PTC) component, a voltage-dependent resistor, a first conductive lead and a second conductive lead. The PTC component includes a PTC layer, a first electrode layer and a second electrode layer. The PTC layer is provided with two opposite surfaces. The first electrode layer and the second electrode layer are respectively disposed on the two opposite surfaces of the PTC layer. The voltage-dependent resistor is connected to the second electrode layer. The first conductive lead is connected to the first electrode layer, and the second conductive lead is connected to the voltage-dependent resistor. The PTC component is provided with a rated voltage that is between 40% and 200% of the voltage-dependent voltage measured by the voltage-dependent resistor at 1 mA. The present composite electric circuit protection device has excellent tolerance. In the presence of overcurrent and overvoltage, the PTC component can
