A 30.3 KB PDF on the 2SK2659, listed in the schematic section but in practice the documentation of a single N-channel FET, as indicated by the JIS 2SK prefix. Content should cover pin assignment, the outline drawing and the main electrical limits. Repair technicians consult such a file when a power MOSFET reads shorted, when checking polarity before replacement and when evaluating substitutes. Check that the package on the board matches the one drawn in the sheet.
