ABSTRACT:
An ESD protection device is provided. The ESD protection device comprises an SCR and an ESD detection circuit. The SCR is coupled between a high voltage and a ground and has a special semiconductor structure which saves area. When the ESD detection circuit detects an ESD event, the ESD detection circuit drives the SCR to provide a discharging path.
