1. An electrostatic discharge (ESD) protection device comprising:

  • a substrate;

    a first doped region formed in the substrate for connecting to a bonding pad; and

    a second doped region formed in the substrate for connecting to a power node, wherein the second doped region is separated from the first doped region by only the substrate region, wherein the ESD protection device comprises no gate above the first and second doped regions, wherein the ESD protection device comprises no isolation structure between the first and second dope regions, and wherein the first and second doped regions are positioned such that current flows in one direction between the bonding pad and the power node through the substrate.
