Part documentation for the 2SK2987, provided as a 426 KB PDF. The 2SK designation follows the Japanese JIS standard for N-channel field-effect transistors, so the file is best treated as a datasheet even though it is catalogued with schematics. Bench use includes confirming pinout and package, checking on-resistance and voltage ratings, and selecting a substitute with suitable characteristics when the original is unavailable. Verify the part code on the device 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.
