A 43.8 KB PDF for the 2SD2565 transistor, its name ending in _E. Although classified as a schematic, the file is most likely a datasheet, as the JIS prefix 2SD…

Component data for the 2SD2130 NPN transistor, a PDF of about 209 KB. The name carries no board or device information; it is a part sheet following the Japanese 2SD…

Datasheet for the 2SD2117, filed as a schematic but actually a component specification in PDF form, about 67.5 KB.

This 145 KB PDF carries the 2SD1722 part number and nothing more, so it is best treated as that transistor's datasheet.

A compact 30.6 KB PDF tied to the 2SD1666 part number, catalogued among schematics. In Japanese JIS designations, 2SD stands for an NPN bipolar transistor meant for…

PDF reference, 67.1 KB, for the 2SD1627 transistor, stored in the schematic section. The name carries nothing besides the part number.

Transistor sheet for the 2SD1626, 87.9 KB in PDF format, filed as a schematic. In JIS codes, 2SD denotes an NPN bipolar device for low-frequency or power circuits.

Very small 22.2 KB PDF relating to the 2SD1999, filed as a schematic. The name offers nothing but the part code, which follows the JIS scheme where 2SD denotes an NPN…

The 3SK263 is covered by an 82.7 KB PDF placed in the schematic category, though a part-number name like this normally indicates a component datasheet.

A 429 KB PDF titled 2SK2789 and stored among schematics, most likely the datasheet for that part.
