Abstract
An improved surge protecting circuit which can protect the power source and the internal and external circuit elements of an electronic product by absorbing external surges through ground. The protecting circuit according to the present invention is connected between an AC input terminal and an AC ground pattern. The protecting circuit includes surge absorption patterns having an arc discharge gap of preferably 0.25 mm, which is less than a specified safety distance, which is typically 5 mm, so as to absorb the external surges transmitted through the terminal to the AC ground pattern and a varistor connected between the surge absorption patterns and the AC ground patterns.
