PDF of 75.0 KB covering the 2SD2176 part. Though listed as a schematic, a file named after a single JIS transistor number is most likely a datasheet, and the 2SD prefix…

Single-part PDF of 47.0 KB for the 2SD2583, listed as a schematic but most probably a datasheet.

Datasheet-style document for the 2SD2581 transistor, saved as a 43.7 KB PDF and filed in the schematic category.

Compact 42.8 KB PDF for the 2SD2537, listed as a schematic though the name points to a single-component datasheet.

Part 5LP01N is documented in this 27.9 KB PDF, filed under schematics. The name is limited to the part code; in this family LP appears to designate a P-channel MOSFET…

A 41.4 KB PDF covering the 5HP02C part, indexed under schematics. Only the component code is present in the name, with C most likely denoting the package type.

Component documentation for the 4N38 optocoupler, filed under schematics though it is in practice a part datasheet in PDF form of about 140 KB.

Part datasheet for the 2SD1782K, an NPN transistor named under the Japanese JIS scheme, with the K suffix indicating a particular variant or package.

This PDF of about 124 KB covers the 2SD2114 transistor with a KS suffix; the suffix is not explained by the name and may denote a gain class or package variant.

The 2SD2079 PDF, 219 KB in size, is indexed as a schematic yet corresponds to a single discrete component.

The name offers nothing beyond the 2SD2500 part number, and the 250 KB PDF is almost certainly that transistor's datasheet.

The 2SD1683 is the subject of this 146 KB PDF, which is catalogued as a schematic although the name is a transistor part number.

Part reference for the 2SD1669, supplied as a 107 KB PDF and filed in the schematic section.

Transistor documentation for the 2SD1667, 136 KB in PDF format. Nothing beyond the part number appears in the name.

PDF of 119 KB for the 2SD1664, written in lowercase in the original name and filed as a schematic.

At 198 KB, the PDF for the 2SD1658 is one of the larger sheets in this group, though it still names only the part.

Datasheet PDF, 60 KB, for the 2SD1650, with the name given in lowercase and filed under schematics.

The 2SD1628 is covered in this 88.3 KB PDF, catalogued with schematics though it relates to a single transistor.

Indexed as a schematic, this 109 KB PDF is titled 2SD1621, a transistor part number, so treat it as a datasheet rather than a circuit diagram.

Part number 2SD1424 with an unexplained _E suffix names this 41.4 KB PDF, indexed among schematics but most likely a datasheet for the transistor.

Component documentation for the 2SD1881 transistor, supplied as a 90.6 KB PDF and catalogued as a schematic, though a part number like this normally points to a…

PDF covering the 2SD1880, about 88.9 KB, listed as a schematic but named after a single semiconductor part.

Small 33.0 KB PDF for the 3SK144, catalogued as a schematic but named for an individual semiconductor, so it is most likely a datasheet.

Document for the 3SK227 semiconductor, stored as a 30.6 KB PDF and catalogued under schematics.

Reference sheet for the 3SK180 semiconductor in PDF form, roughly 173 KB, catalogued as a schematic.

Compact 43.6 KB PDF named for the 3N249 and filed as a schematic, although it is almost certainly a component datasheet.

The 3N248 is covered by this 43.6 KB PDF, indexed under schematics but named only by its JEDEC part number.

Part number 2SD2459 names this 41.2 KB PDF, followed by an unexplained E tag; it is catalogued as a schematic.

Largest in this set at 269 KB, the PDF 2SD2414 is catalogued as a schematic, yet its 2SD prefix marks an NPN bipolar transistor under the Japanese JIS scheme.

Catalogued as a schematic, the 40.9 KB PDF 2SD2413 with an E tag relates, by the JIS 2SD prefix, to an NPN bipolar transistor rather than a complete board.

PDF document for the 2SD1995 semiconductor, catalogued under schematics but by its name a component datasheet.

Short 54.7 KB PDF for the 2SD1991A, an NPN bipolar transistor going by its JIS 2SD prefix. The index lists it under schematics.

The 2SD1511 NPN transistor is the subject of this 56.9 KB PDF, filed under schematics in the index. JIS numbering assigns 2SD to low-frequency NPN bipolar parts.

The name carries only a part number, 2SD1905, which points to a semiconductor datasheet even though the entry is filed under schematics.

Filed under schematics, though the file name is simply the JIS part number 2SD1903, so expect a component datasheet in this 131 KB PDF.

Tiny 30.2 KB PDF named 2sk65, a JIS part number that indicates a component datasheet, although it is filed as a schematic.

The 2SK3413LS is documented in this compact 32.2 KB PDF, indexed as a schematic but effectively a component datasheet.
