Part document for the 2sk2575, 35.2 KB in PDF format and catalogued as a schematic. The 2SK prefix in JIS nomenclature marks an N-channel field-effect transistor; the name lists no other specifics. Expect a concise datasheet with pin assignments and electrical limits. Those details let a technician test the transistor correctly, recognise a shorted junction and pick an equivalent with suitable ratings and package. Check the actual component marking first, since neighbouring part numbers can have very different specifications.
