An electrostatic discharge (ESD) protection circuit is provided. A transistor is coupled between a node and a ground, and has a gate coupled to the ground. A diode chain is coupled between the node and a pad, and comprises a plurality of first diodes connected in series, wherein the first diode is coupled in a forward conduction direction from the pad to the node. A second diode is coupled between the node and the pad, and the second diode is coupled in a forward conduction direction from the node to the pad.
