The 2SD2179 transistor is the subject of this 43.9 KB PDF, carrying an _E suffix in its name.

Document for the 2SD1624, a PDF of 144 KB stored in the schematic section; with only a part number in the name it should be treated as a datasheet.

Small PDF of 27.3 KB for the 3LN01N, catalogued as a schematic though the name reads as a discrete transistor part number, so it is most likely a datasheet.

Indexed as a schematic, this PDF is named 2SD1459, a Japanese JIS designation that points to a datasheet for an NPN transistor rather than a board diagram.

Filed under schematics, this 74.1 KB PDF is named after the 2SD1953, which in Japanese JIS numbering is an NPN transistor for low-frequency applications.

A compact 36.0 KB PDF for the 2SD1949 transistor. The 2SD prefix in the JIS system designates an NPN device for low-frequency circuits, so the content is expected to be…

Datasheet-style PDF of 83.8 KB named for the 2SD1940, an NPN transistor under Japanese JIS numbering, in which 2SD stands for NPN low-frequency types.
