Abstract
An electrostatic discharge (ESD) protection device includes a pad, a diode, a gate ground NMOS (GGNMOS) transistor and a thyristor. The diode includes an anode connected with the pad. The GGNMOS transistor is connected between a cathode of the diode and a ground terminal. The thyristor is formed between the diode and the ground terminal when an ESD current may flow from the pad.
