Abstract
The present invention provides an ESD protection circuit having at least one semiconductor-controlled rectifier and a diode. The SCR having a floating anode gate is connected between a first circuit node a second circuit node. The diode is connected between an anode and a cathode gate of the SCR to activate the SCR so that a potential between the first circuit node and second circuit node can be clamped at about a holding voltage of the SCR during an ESD event.
