Abstract
Disclosed examples provide integrated circuits including a source down transistor with a gate, a body region, an n-type source region, an n-type drain region, a p-type body contact region below the n-type source region which extends to a first depth, along with a protection diode which includes an n-type cathode region, and a p-type anode region below the n-type cathode region, where the breakdown voltage of the protection diode is defined by adjusting the relative doping concentrations and/or the vertical locations of the p-type anode region with respect to the n-type cathode region.
