Datasheet-style PDF, 326 KB, titled with the 2SK2823 part number and stored among schematics. Under the Japanese JIS standard, 2SK indicates an N-channel FET. The document should help a technician identify gate, drain and source, check voltage and current limits against the circuit, and compare characteristics when a direct replacement cannot be found. The name contains no manufacturer, package or revision, so confirm those against the actual marking before ordering parts or soldering in a substitute.
