Zusammenfassung:An electrostatic discharge (ESD) protection device having a source region coupled to a first electrical node, a first drain region coupled to a second electrical node different from the first electrical node, and an extended drain region between the source region and the first drain region. The extended drain region includes a number N of electrically floating doped regions and a number M of gate regions coupled to the second electrical node, where N and M are integers greater than 1 and N is equal to M. Each electrically floating doped region of the N number of floating doped regions alternates with each gate region of the M number of gate regions.
