The 2SJ312 is documented in this 362 KB PDF, catalogued as a schematic. Beyond the part number the name says nothing about the equipment involved.

Under the schematic category, this 99.0 KB PDF titled 2SJ187 should be the datasheet for a P-channel FET, as the JIS 2SJ prefix indicates.

PDF of 56.2 KB named 2SD1391, a JIS designation for an NPN low-frequency bipolar transistor, and presumably its datasheet although indexed under schematics.

Separate from the UTC version, this 43.2 KB PDF covers the 2SD965 and bears an _E suffix that the name leaves unexplained.

Datasheet-type PDF of 47.9 KB for the 2SD894, placed under schematics. The name holds only the part number, which follows JIS conventions where 2SD indicates an NPN…

Part documentation for the 2SC4519, an 85.9 KB PDF that is categorised as a schematic but is a component datasheet.

Reference sheet for transistor 2SC4474, supplied as a 109 KB PDF and listed among schematics.

Part code 2SC4440 is all the 97.3 KB PDF name reveals, and the catalogue places it under schematics.

At 466 KB, this PDF for the 2SC4325 sits under schematics, yet the name is a bare transistor part number, so expect a component datasheet.

Listed under schematics, this 133 KB PDF named 2SC5108FT appears to be the datasheet for an FT-suffixed variant of the 2SC5108 transistor.

For the 2SC5107 transistor, this 242 KB PDF is categorised as a schematic, though the bare part-number name points to a datasheet.

PDF reference for the 2SC4248 transistor, 300 KB in size. Beyond the part number the file name gives no information about manufacturer, package or revision.

Part 2SC5095 gives this 296 KB PDF its name, and that is the only detail available: no board, revision or manufacturer is stated.

A 92.1 KB PDF labelled 2SC4106 and placed among the schematics. The name carries no model or board number, only the part designation; in the Japanese JIS/JEITA system…

Reference sheet in PDF form, about 123 KB, for the 2SC5374 NPN transistor in the Japanese 2SC numbering series.

PDF datasheet for the 2SC5368, an NPN bipolar transistor under the JIS 2SC scheme, filed under schematics and around 188 KB.

PDF datasheet, 42.4 KB, for the 2SC5305LS, a suffixed version of the 2SC5305 NPN transistor.

Reference PDF for the 2SC3648 transistor, 120 KB. Under JIS naming, devices starting with 2SC are NPN bipolar transistors.

The 2SC5317 transistor is the subject of this 122 KB PDF, which the index lists as a schematic though the name matches a datasheet.

PDF of 137 KB identified only by the part number 2SC2782, filed with schematics but almost certainly a transistor datasheet.

Datasheet-style PDF for the 2SC2716 transistor, 334 KB, catalogued under schematics. Per JIS naming, the 2SC prefix means an NPN bipolar transistor.

Datasheet-type PDF of 215 KB for the 2SC2655, listed as a schematic. The JIS system uses 2SC for NPN bipolar transistors.

Datasheet-style PDF named after the 2SA1700, a Japanese standard transistor number, stored in the schematic category of the index.

Lowercase-named PDF for the 2SB1474 transistor, about 54 KB, stored in the schematic category but most likely a manufacturer datasheet.

The 2SA1621 is covered by this 194 KB PDF, listed among schematics but really describing one discrete semiconductor.

Indexed as a schematic, this compact 30.5 KB PDF is named for the 2SA1529, a JIS transistor number, and is best read as that part's datasheet.

Here is a 157 KB PDF named after the 2SA1479, filed as a schematic yet most likely a transistor data sheet. Under JIS rules, 2SA denotes PNP polarity.

Short 42.0 KB PDF describing the 2SB858 transistor, its name giving only the part number. Japanese JIS designations beginning 2SB denote low-frequency PNP transistors.

PDF for the 2SA2066 transistor at about 201 KB, catalogued with schematics but representing a component datasheet.

PDF data for the 2SA1838, sized 87.4 KB and stored in the schematic category of the index.

PDF sheet for the 2SA1832FT, a variant of the 2SA1832 whose FT suffix most likely denotes a specific package version, though the name does not explain it.

Documentation in PDF for the 2SA1832F, a suffixed version of the 2SA1832, 231 KB in size and indexed as a schematic.

PDF datasheet of 42.8 KB for the 2SA1011 transistor, catalogued in the schematic category though it is really component reference data.

At 228 KB, this PDF for the 2SA1771 is among the larger sheets in the set, indexed as a schematic though it bears a JIS transistor code.

Reference document for the 2N7002MTF, a 205 KB PDF stored with schematics. The base number 2N7002 is a well-known small-signal N-channel MOSFET, and the MTF letters are…

A 444 KB PDF for the 2N7000 carrying the tag Sam, which probably identifies the manufacturer that issued it, although the name does not expand the abbreviation.
