Claim Text:
1. An apparatus, comprising: an anode terminal; a cathode terminal; a semiconductor substrate; an epitaxial layer disposed on the semiconductor substrate; an isolation region including a first heavily doped portion and a second heavily doped portion; a well region disposed between the isolation region and the cathode; a junction field-effect transistor (JFET) portion having a channel disposed within the semiconductor substrate and defining a first portion of an electrical path between the anode terminal and the cathode terminal, the first portion of the electrical path including the first heavily doped portion; and a diode portion formed within the semiconductor substrate and defining a second portion of the electrical path between the anode terminal and the cathode terminal, the diode portion being serially coupled to the channel of the JFET portion, the second portion of the electrical path including the second heavily doped portion.
