Covering the 2SK2952, this PDF of 414 KB is a discrete transistor document rather than a full circuit, as the JIS 2SK prefix indicates an N-channel field-effect transistor. Its tables and diagrams give the ratings and pinout needed when a switching device has failed. Use them to test the suspect part, orient a replacement on the footprint and confirm that any substitute meets the voltage and current requirements. Match the exact part marking before ordering.
