The 2SC5144 is the only detail this 206 KB PDF name carries; despite the schematic label it is presumably the device datasheet for that transistor.

A 42.8 KB PDF for the 2SC5639, placed under schematics although its name is a bare part number pointing to a transistor datasheet.

Named only after the part 2SC4363, this 88 KB PDF is catalogued as a schematic but is most likely the manufacturer datasheet for that transistor.

Despite sitting in the schematic category, this 99.9 KB PDF is named after the 2SC4164 and should therefore contain transistor specifications rather than a circuit…

The name of this 156 KB PDF is just the part number 2SC4134, so despite its schematic label it should be the datasheet for that transistor.

A 475 KB PDF referencing the 2SC5092 transistor type; the 2SC prefix denotes an NPN bipolar device under the Japanese JIS numbering system.

Brief 35.7 KB PDF covering the 2SC5536 NPN transistor, filed as a schematic in the index.

For the 2SC5534 transistor, this 44.8 KB PDF sits in the schematic category but, going by the JIS 2SC code for NPN bipolar devices, is the part datasheet.

Here is a 49.4 KB PDF for part 2SC4067, placed under schematics but named like a manufacturer datasheet.

Component reference in PDF form for the 2SC4002, 77.6 KB, filed in the schematic category.

Filed under schematics, the 2SC3993 PDF (107 KB) is far more likely a component datasheet, since the name is simply a JIS transistor part number.

Reference PDF for the 2SC5420 transistor, 69.2 KB, indexed as a schematic though the bare part number points to a component datasheet.

Small 44.3 KB PDF describing the 2SC5419, with the _E suffix seen across this series. It sits in the schematic category, yet the name is a JIS transistor number: 2SC…

Compact 30.5 KB PDF for the 2SC3923, named by part number alone and sorted into schematics.

Brief datasheet-type PDF for the 2SC3920 at 30.5 KB, indexed under schematics. The file name contains only the part number.

The 2SC5416 base part is described in this 45.8 KB PDF, indexed as a schematic, with an LS variant held in a separate file.

Named simply 2SC4984, this 48.8 KB PDF is catalogued as a schematic yet points to a discrete semiconductor.

Single-part reference for the 2SC4864 in a 118 KB PDF, catalogued as a schematic. Apart from the part number, the name gives no information.

Labelled 2SC4835 with an _E suffix, this 41.5 KB PDF is filed as a schematic but refers to a JIS-numbered NPN transistor, indicated by the 2SC prefix.

The 2SC3502 NPN transistor is the subject of this 157 KB PDF, which the index files under schematics.

PDF component sheet for the 2SC3481, 131 KB in size and catalogued with schematics. The file name holds just the part number; the 2SC prefix is the JIS designation for…

Part number 2SC3401 is the only information in the name of this 87.3 KB PDF, so no device or board is identified.

A 97.4 KB PDF for the 2SC3151, an NPN bipolar transistor according to its JIS 2SC designation.

Component reference for the 2SC3124, a 294 KB PDF indexed as a schematic. The JIS 2SC designation identifies it as an NPN bipolar transistor, normally marked C3124.

Small 42 KB PDF for the 2SC3077, filed as a schematic. The trailing _E in the name is not explained by the file name itself.

An 84.6 KB PDF for the 2SC3071, filed as a schematic. The name supplies nothing beyond the part number, so this is probably a compact datasheet.

A 508 KB PDF filed under schematics, named only with the JIS part number 2SC2996. The 2SC prefix identifies an NPN bipolar transistor, so the document is probably a…

Indexed as a schematic, this 187 KB PDF is named after the 2SC2880, which the JIS 2SC prefix identifies as an NPN bipolar transistor.

Datasheet-style PDF of 170 KB for the 2SC1627A, the A-suffixed variant of a JIS-numbered NPN bipolar transistor, indexed as a schematic.

Filed as a schematic, this 52.8 KB PDF covers the 2SB709A, a PNP bipolar transistor in JIS terms, with the A suffix indicating a variant of the 2SB709 that may carry…

At 249 KB this PDF is the largest in the group and covers the 2SA1618, indexed as a schematic but in practice a transistor reference.

The 2SA1592 is covered by this 156 KB PDF, filed as a schematic although the name refers to a single semiconductor.

Small 30.2 KB PDF for the 2SA1968LS, a variant of the 2SA1968 identified by the LS suffix; what that suffix denotes is not explained in the name and should be confirmed…

The 2SA1315 PNP transistor, per the Japanese JIS 2SA prefix, is the subject of this 220 KB PDF.

The 2SA1298 is covered by this 203 KB PDF, catalogued as a schematic but named only after the component.

Datasheet PDF of 42.2 KB for the 2SA1883, identified only by its part number. Japanese JIS numbering uses 2SA for PNP bipolar transistors, so the content describes a…

Component sheet for the 2SA1866 PNP bipolar transistor, stored as a 55.4 KB PDF. The 2SA prefix follows Japanese JIS conventions for PNP devices.

At 320 KB, this PDF for the 2SA1163 is the largest of this group of 2SA files and likely a full manufacturer datasheet with characteristic curves.

A 207 KB PDF for the 2SA1736, filed in the index as a schematic but named after a single semiconductor part rather than a board.

A 64 KB PDF covering the 2N7218, indexed as a schematic though the file name is a plain JEDEC part number and the content is most likely a single-device datasheet.
