PDF reference for the 2SK1465, sized 121 KB. The 2SK prefix comes from Japanese semiconductor numbering and indicates an N-channel FET, so despite the schematic label the document should describe that single component. Bench uses include checking pinout before probing, comparing measured gate threshold or leakage to specification and selecting an equivalent with matching ratings and package. Any PDF viewer will display it; make sure the part on the board carries the same number.
