A 141 KB PDF filed under schematics with the name 80EPF02S, a part code in International Rectifier style where the trailing S most likely denotes a package variant of the 80EPF02. Treat it as a component datasheet; no device or board is stated. It helps verify footprint, pin assignment and ratings before soldering in a replacement. Since a separate 80EPF02 sheet exists, compare the full marking on the part carefully, as package variants are not always interchangeable on a board.
