Part number 2SK2124 is the sole detail here, in a 32 KB PDF catalogued as a schematic and most likely a short datasheet.

The 2SK1867 is named in this small 33.9 KB PDF, catalogued under schematics. Because 2SK is the Japanese prefix for N-channel field-effect transistors, expect a brief…

Short 36.3 KB PDF on the 2SK1803. Part numbers prefixed 2SK are N-channel field-effect transistors in the Japanese JIS registration system, and this file is most likely…

Labelled 2SK1451, this 111 KB PDF sits in the schematic section but by name looks like a transistor data sheet. The JIS 2SK code belongs to N-channel FETs.

Listed as a schematic, this 105 KB PDF is named only after the 2SK1430 transistor and is probably its datasheet.

The 2SK601 is the only information in the name of this 33.2 KB PDF, which is filed under schematics yet most likely contains a datasheet, as 2SK numbers designate…

A 31.0 KB PDF for the 2SJ597, stored in the schematic category although it is named like a single-part datasheet.

Datasheet for the 2SJ412 P-channel field-effect transistor, provided as a 328 KB PDF; the larger size suggests detailed curves and package drawings.

Datasheet PDF of 107 KB for the 2SJ381, indexed as a schematic. The prefix 2SJ comes from the Japanese JIS discrete semiconductor scheme and denotes a P-channel FET.

Component datasheet in PDF form for the 2SJ284, roughly 81.4 KB. The file name names only this part, with no device, board or revision mentioned.

A 103 KB PDF covering the 2SD1063, filed as a schematic although the name points to a single semiconductor rather than a device.

Only 21.9 KB, this PDF relates to the 2SD1048 and is indexed among schematics, though the name identifies a discrete part.

This 234 KB PDF covers the 2SC4738F, indexed as a schematic though it concerns one transistor.

At 280 KB, this PDF for the 2SC5233 is one of the larger documents in the series and is indexed as a schematic, though the name identifies a single part.

PDF of about 99 KB for the 2SC4770, filed under schematics though the name points to a transistor datasheet rather than a board diagram.

Covering the 2SC4612, this 155 KB PDF is indexed as a schematic but is in practice a transistor datasheet, as only the part number appears in the name.

An 84.4 KB PDF for the 2SC4547, sorted into schematics but named like a single-component datasheet.

The 2SC5122 is named in this 171 KB PDF, which the index lists under schematics even though the title is only a component number, suggesting a datasheet.

The 2SC4253 transistor is documented in this 303 KB PDF, indexed among schematics. Only the part number is given in the name; maker and revision are not stated.

Small 92.6 KB PDF bearing only the part number 2SC4219. Although the catalogue lists it as a schematic, the 2SC prefix, the JEITA code for an NPN bipolar transistor…

PDF document of 331 KB named after the 2SC4116 part number, filed in the index under schematics.

The 2SC4108 is the only detail this 94 KB PDF name provides, and the index files it as a schematic.

A 103 KB PDF named only after the part 2SC3992, indexed as a schematic but in practice almost certainly a transistor datasheet.

Reference sheet for the 2SC3990 transistor, stored as a 104 KB PDF and catalogued under schematics.

Component sheet covering the 2SC3780, a JIS-designated NPN bipolar transistor, in a 126 KB PDF.

Data sheet material for the 2SC3772 NPN transistor in a 128 KB PDF, filed among schematics. The 2SC prefix follows the JIS convention for Japanese bipolar transistors.

For the 2SC5305? No: this 94.6 KB PDF covers the 2SC3705, an NPN bipolar transistor by its JIS designation, and is indexed under schematics.

Covering the plain 2SC1627 without suffix, this 211 KB PDF sits in the schematic category but names only a part number.

The 2SA1525 transistor gives its name to this 30.8 KB PDF, which is filed as a schematic but presumably contains the datasheet.

The 2SA1362 gets this 201 KB PDF, which carries only the part number and is therefore most likely the manufacturer datasheet rather than a board schematic.

The 2SA1352 is the only identifier in this 149 KB PDF name, so treat it as the transistor datasheet even though the index calls it a schematic.

PDF reference for the 2SA1968, 91.3 KB, indexed as a schematic though the bare part-number name points to a transistor datasheet.

Transistor datasheet in PDF format, 182 KB, for the 2SA1933, listed in the schematic category of this index.

The 2SA1805 PNP transistor, as indicated by its JIS 2SA prefix, is documented in this 176 KB PDF datasheet.

The 2SA1709 is documented in this 154 KB PDF, which the index lists as a schematic though its name contains only the part number.

Specification PDF for the 2SA1706 transistor, 140 KB, catalogued under schematics despite naming only a part.

Listed under schematics, this 127 KB PDF is named for the 2N6439 with an RE suffix that the name leaves unexplained.

A comparatively large 707 KB PDF filed as a schematic, named only 2N6427, a JEDEC 2N-series discrete semiconductor number.

A 708 KB PDF indexed under schematics and named only with the part number 2N5771, with no board, revision or device given.

The name gives just 2N5638, so this 26.3 KB PDF has no board, device or revision information.
