The power semiconductor device comprises a base that includes a substrate and an epitaxial layer located above the substrate, with the base comprising a unit area and a peripheral area surrounding the unit area. A junction layer is located within the peripheral area and above the epitaxial layer. A barrier layer is located within the unit area and above the epitaxial layer. A first electrode is located on the junction layer and a second electrode is located on the barrier layer. The epitaxial layer includes a doped channel located within the peripheral area, extending between the junction layer and the base substrate. Current flows from the substrate through the doped channel and the junction layer to the first electrode.
