An electrostatic discharge (ESD) protection device for protecting an I/O port of an electronic circuit from overvoltage and a coil structure for use in an ESD protection device. The ESD protection device includes: a plurality of inductors that are serially coupled in a line, where a node is formed between two neighboring inductors; and a plurality of protection arrangements adapted to conduct charges to one provided potential when an overvoltage is applied, where each of the protection arrangements is connected with one of the nodes, and where the serially coupled inductors are magnetically coupled with each other.
