PDF reference sheet, 36.2 KB, for the 2SK1607. In the Japanese semiconductor naming scheme the 2SK series covers N-channel FETs, so this is a component datasheet even though it sits in the schematic category. The file name gives only the part number. Use the ratings and characteristic tables to evaluate a replacement, the outline drawing to confirm footprint and pin order, and confirm the device marking on the board matches this number.
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.
