Claim 17:
18. The ESD protection circuit of claim 14, wherein the second trigger circuit has a threshold voltage, when a voltage of the first terminal of the second trigger circuit is higher than a voltage of the second terminal and a difference therebetween exceeds the threshold voltage of the second trigger circuit, the second trigger circuit conducts; and the second discharge component has a threshold voltage, and when a voltage of the gate of the second discharge component is higher than a voltage of the first source/drain or the second source/drain and a difference therebetween exceeds the threshold voltage of the second discharge component, the second discharge component conducts, and the threshold voltage of the second trigger circuit is greater than the threshold voltage of the second discharge component.
