A separate 85.2 KB PDF on the 2SK3065, filed under the schematic category. It may be a different revision or source document from the SOT-89 specific file in this index, but the name gives only the part number. The 2SK prefix marks an N-channel field-effect transistor in the JEITA system. Consult it for pin assignment, voltage and current ratings and package data, and compare it with the other sheet if figures or markings seem to disagree.
