A very small PDF of 23.8 KB named for the 2SK2797, filed under schematics. The 2SK prefix follows the JIS naming convention for N-channel field-effect transistors, so the file is probably a short datasheet or a single-page summary. Even a brief sheet is useful for confirming pinout and key ratings before replacing a failed MOSFET. Given the size, curves and full package drawings may be missing. Verify the part marking on the board and consult a fuller datasheet if detailed parameters are needed.
