Component document for the 2SK212 in PDF form, 156 KB, indexed under schematics. Japanese JIS numbering assigns the 2SK prefix to N-channel FETs, so the file should be the datasheet for that device rather than a board drawing. Contents normally include a pinout diagram, ratings tables and typical curves. Use it to identify the legs before measuring in circuit, and when picking a substitute compare voltage, current and package rather than trusting a generic cross-reference list.
