ABSTRACT:
A method and a device are disclosed herein for protecting a circuit including a first terminal and a second terminal from electrostatic discharges. The device comprises at least one current path, wherein each current path of the at least one current path includes a transistor and a first circuit element. A first load terminal of the transistor is coupled to the first terminal of the circuit. A second load terminal of the transistor is coupled to a control terminal of the transistor and to a first terminal of the first circuit element. A second terminal of the first circuit element is coupled to the second terminal of the circuit. A well terminal of the transistor is coupled to the second terminal of the circuit via a second circuit element.
