Abstract
An electrostatic discharge device includes a first protection element including a MOS transistor type first diode, which provides a first capacitor including a first insulation layer, and provides a first path between an input/output pad and a power supply voltage line using the first diode, for discharging static electricity, a second protection element providing a second path between the input/output pad and a ground voltage line for discharging the static electricity, a trigger circuit including a resistor that is connected in series to the first capacitor, and a power clamp element providing a third path for discharging the static electricity between the power supply voltage line and the ground voltage line by a voltage applied to the resistor.
