Short PDF of 23.2 KB named for the 2SK2324 part. In JIS nomenclature 2SK denotes an N-channel FET, so this schematic-labelled file is presumably a brief datasheet. Expect absolute maximum ratings, key electrical parameters and a package diagram showing gate, drain and source. That information supports in-circuit testing and selection of a replacement with equal or better voltage and current capability. Open with a PDF viewer and compare the physical marking, including any suffix, with the document before substituting the part.
