Abstract
Some embodiments relate to a silicon controlled rectifier (SCR) that includes a current path which couples an SCR anode to an SCR cathode. The current path includes a first vertical current path component coupled to the SCR anode, and a second vertical current path component coupled to the SCR cathode. A horizontal current path component includes a first well region and a second well region that meet at a junction lying along a first plane. The first and second well regions cooperatively span a distance between the first and second vertical current path components. The first and second vertical current path components mirror one another symmetrically about the first plane.
