Abstract

The present invention relates to a circuit protection device. A circuit protection device includes a laminate having a common mode noise filter and an electro static discharge (ESD) protection device laminated; first and second external electrodes respectively formed on one and the other side surfaces of the laminate; and a third external electrode formed on a top or bottom surface of the laminate. In the circuit protection device, the external electrode connected to the ESD protection device is formed on a bottom surface of a composite device, thereby reducing parasitic capacitance. Accordingly, distortion of signals can be prevented, thereby enhancing reliability.
