For the 2SA1356, this 177 KB PDF carries just the part number, so it is most probably the device datasheet rather than a full circuit diagram.

Covering the 2SA1242, this 212 KB PDF carries only the part number in its name, so it is best treated as the component datasheet despite the schematic label.

Largest sheet in this group at 469 KB, this PDF for the 2N5962 is listed as a schematic, though it is likely a detailed datasheet with graphs.

PDF datasheet of about 125 KB covering the 2SD1766 NPN transistor, part of the Japanese JIS 2SD numbering.

PDF documentation for the 2SK772, size 77.7 KB. Within the Japanese JIS numbering scheme, 2SK identifies N-channel field-effect transistors, so the content is most…

An 87 KB PDF for the 2SC2412K, an NPN transistor named under the Japanese JIS convention with a K suffix.

A small 43 KB PDF named after the 2SC2344 NPN transistor, part of the Japanese JIS 2SC series.

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

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

Datasheet-type PDF of 31.1 KB for the 2SK3412 semiconductor, stored under the schematic category.

Datasheet-style PDF for the 2SK3018, indexed here under schematics, though the 2SK prefix marks a Japanese JIS-registered N-channel field-effect transistor rather than a…

Part 2SK1890, documented in a 96.7 KB PDF placed in the schematic category. Japanese JIS numbering reserves 2SK for N-channel FETs, so this is a component datasheet…

Covering the 2SK1435, this 105 KB PDF is indexed as a schematic yet named after one discrete component, which suggests a datasheet.

Reference PDF for the 2SK1382 N-channel MOSFET, 389 KB, listed in the schematic category of the index.

The name of this 92.4 KB PDF consists only of 2SJ255, a Japanese JIS designation where 2SJ marks P-channel FETs.

Here is a 144 KB PDF for the 2SC4728, filed as a schematic but carrying a discrete part number.

Here is the 2SC5242 documentation as a 173 KB PDF, placed in the schematic category but evidently a part datasheet going by its name.

Part datasheet for the 2SC5589 in PDF, 298 KB, grouped with schematics in this index. The file name states only the part number.

A 99.4 KB PDF for the 2SC3779 transistor. The file name gives only the part number; the 2SC prefix follows the Japanese JIS scheme for NPN transistors, so this is almost…

Transistor datasheet in PDF form, 188 KB, named 2SC5352 without any device or board reference.

Datasheet PDF of 248 KB for the 2SC3138, an NPN bipolar transistor going by its Japanese JIS 2SC prefix.

Indexed as a schematic, this 199 KB PDF actually carries only the part number 2SC1959, pointing to a single NPN bipolar transistor under the JIS naming scheme.

By Japanese JIS numbering the 2SB643 is a PNP bipolar transistor, so this 44.2 KB PDF labelled as a schematic should be its datasheet, with _E probably marking an…

PDF for the 2SA1701, a JIS-coded semiconductor; the index lists it as a schematic, yet a bare part number like this is almost always a manufacturer datasheet.

A 144 KB PDF for the 2SA1317 transistor, listed under schematics but almost certainly a part datasheet given that the name is just the component code.

Reference PDF of 96.5 KB tied to the 2N6237, a JEDEC-numbered discrete semiconductor; the index lists it as a schematic, but it most likely holds the device datasheet.

Component datasheet for the 2SD1851 transistor, supplied as a 93.4 KB PDF and classed as a schematic in the index.

A 152 KB PDF for the 2SD1816 transistor, listed in the schematic section. The name provides the part number only.

Datasheet-style PDF of 179 KB named for the 2SD2525, catalogued as a schematic but describing just one component.

A 167 KB PDF identified only by the 2SD2481 part number, which points to the datasheet for that transistor rather than a board schematic.

Component data for the 2SK3448, filed under schematics but in practice a short datasheet-style PDF of 27.6 KB.

Covering the 2sk2571, this 24.5 KB PDF is a short document classed as a schematic, though its name is just a part number and the content is likely a concise datasheet.

PDF datasheet for the 2SK444, sized 92.5 KB and listed in the schematic category. The 2SK prefix places it in the Japanese JIS series of N-channel FETs, so the document…

Part datasheet in PDF form, 420 KB, for the 2SJ401 P-channel FET; the catalogue lists it as a schematic.

Stored as a 149 KB PDF, this entry covers the 2SD1236L and sits in the schematic category, though the name points to a single transistor.

Lowercase-named PDF for the 2sc4997, 51.2 KB, indexed as a schematic. Only the part number is given.

At 31.1 KB, this compact PDF for the 2SC4976 is filed as a schematic, though the part-number name indicates a component sheet.

The 2SC4935 is covered by this 176 KB PDF, filed as a schematic but, judging by the bare JIS part number, almost certainly the transistor datasheet.

A 320 KB PDF dealing with the 2SC3123, an NPN bipolar transistor by its Japanese JIS 2SC code.

A 320 KB PDF dedicated to the 2SC3011, indexed as a schematic but most likely a transistor datasheet. Nothing besides the part number appears in the name.
