This 18.9 KB PDF for the 2SD965 carries a UTC tag, which commonly refers to Unisonic Technologies, a maker of second-source discrete semiconductors. Filed as a schematic, it is effectively a datasheet for an NPN low-frequency transistor under JIS 2SD numbering. Second-source sheets may differ from the original in package options or ratings, so compare it against the separate 2SD965 document in the index and against the marking on the part before relying on pinout or limits.
