Embodiments include a system, apparatus, and method for ESD power clamps. Aspects include protecting a circuit using an ESD power clamp device. The ESD power clamp device includes a trigger circuit having a resistor-capacitor network and an inverter stage circuit, wherein the trigger circuit is configured to detect an ESD event. Aspects of the invention further include a timing circuit coupled to the trigger circuit and a timing controlled transistor, wherein the timing circuit controls the timing controlled transistor to prevent the capacitor in the RC network from charging when the timing circuit is initiated. Aspects also include a clamp transistor coupled to the trigger circuit, wherein the clamp transistor is controlled by a signal received from the trigger circuit, and a timing controlled transistor coupled to the trigger circuit and the timing circuit, where the timing controlled transistor switches states based on the output of the timing circuit.
