Small 30.0 KB PDF covering the 2SK2047 transistor. Under the JIS naming system the 2SK prefix marks an N-channel FET, so this is best treated as a part datasheet rather than a board schematic, even though it is catalogued as one. Technicians open it in any PDF reader to check gate, drain and source pin assignment, on-resistance and breakdown ratings when choosing a substitute. No maker, package or revision appears in the file name, so verify the part marking on the board first.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @cyberlanelectonik. Enginerys does not host this file.
