Brief 114 KB PDF for the 2SK2965, labelled a schematic but by its name a datasheet for a single N-channel field-effect transistor, as the JIS 2SK prefix indicates. Expect pinout, package drawing and maximum ratings. These details let a repairer test the part in circuit or out, identify gate, drain and source on the footprint, and pick a compatible replacement. Check that the number on the component body matches, since abbreviated markings can mislead.
