A two-terminal power diode has improved reverse bias breakdown voltage and on resistance includes a semiconductor body having two opposing surfaces and a superjunction structure therebetween, the superjunction structure including a plurality of alternating P and N doped regions aligned generally perpendicular to the two surfaces. The P and N doped regions can be parallel stripes or a mesh with each region being surrounded by doped material of opposite conductivity type. A diode junction associated with one surface can be an anode region with a gate controlled channel region connecting the anode region to the superjunction structure. Alternatively, the diode junction can comprise a metal forming a Schottky junction with the one surface. The superjunction structure is within the cathode and spaced from the anode. The spacing can be varied during device fabrication.
