Abstract
An electrostatic discharge protective circuit of the invention includes a silicon controller rectifier (SCR) and a current diverter. The current diverter is used to bypass an initial low current thereby to prevent the SCR from being triggered by the low current. Thus, a trigger current required to activate the SCR can be greatly increased thereby to maintain an internal circuit at a normal operating state.
