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

The 2SC5238 is covered by this 105 KB PDF, filed among schematics but named like a discrete-component datasheet.

Documentation for the 2SC4781 in a 120 KB PDF, indexed as a schematic though the name matches a discrete semiconductor part.

PDF of about 63 KB for part 2SC4618, with a trailing h in the name whose meaning is not stated and may denote a variant or document version.

Small 39.3 KB PDF covering the 2SC4562, with an unexplained _E suffix in the name, listed under schematics.

PDF of about 113 KB identified by the transistor number 2SC4403. The JIS prefix 2SC marks an NPN bipolar transistor, so this document should provide datasheet…

PDF of 60.0 KB named 2SC5127, categorized as a schematic though it should be the device datasheet for that NPN bipolar transistor.

Reference PDF for the 2SC4224, at 97.3 KB, catalogued as a schematic although the name is just a semiconductor part number.

Compact 29.9 KB PDF for the 2SC5776, indexed as a schematic but named with a single semiconductor part number.

Named only 2SC4213, this 289 KB PDF is catalogued as a schematic, yet the JEITA-style 2SC prefix identifies an NPN bipolar transistor, so a component datasheet is the…

Part number 2SC4207 is the sole content of this 257 KB PDF's name, which the index places under schematics.

A 31.3 KB PDF for the 2SC5764, stored with the schematics. The name contains just the semiconductor part number; in Japanese numbering, 2SC identifies an NPN transistor…

The 2SC5567 transistor is the subject of this 49.6 KB PDF, which the catalogue lists as a schematic.

A 129 KB PDF labelled 2SC5562, kept in the schematic section of the catalogue. The name holds only the part number; the 2SC prefix in JIS/JEITA naming identifies an NPN…

Compact 40.8 KB PDF for the 2SC536N, an NPN transistor under JIS numbering, where the trailing N is part of the stated part name.

2SC5720 component documentation in PDF form, 156 KB, indexed as a schematic. The 2SC prefix in Japanese semiconductor numbering identifies an NPN transistor of the…

Reference PDF for the 2SC5489, 31.3 KB in size and filed as a schematic. In the Japanese JIS convention the 2SC prefix identifies an NPN transistor, so the document is…

Filed as a schematic at 106 KB, this PDF bears only the identifier 2SC5070. That code belongs to the Japanese 2SC series of NPN transistors, so the document should be a…

Component reference for the 2SC3963, supplied as a 193 KB PDF in the schematic category.

PDF sheet titled only with the part number 2SC5022, 42.0 KB, placed under schematics. No suffix, revision or maker appears in the name.

Datasheet PDF for the base 2SC5417, 45.9 KB, filed in the schematic section; a separate LS-suffixed variant exists in the same set.

Part documentation for the 2SC3777, a 127 KB PDF whose name identifies a single NPN transistor under the JIS 2SC numbering.

A 100 KB PDF reference for the 2SC4919 transistor, catalogued as a schematic. The 2SC prefix follows the JIS convention for NPN bipolar transistors; manufacturer and…

The 2SC4909 NPN transistor is documented in this 61 KB PDF, listed under schematics but by its name a component datasheet.

The 2SC3689 transistor is the subject of this 89.7 KB PDF, which the catalogue lists as a schematic.

Compact 33.5 KB PDF for the 2SC3664 transistor. The 2SC prefix, under the JIS scheme, signals an NPN bipolar device; nothing else is stated in the name.

Specification document for the 2SC3515 transistor, a 225 KB PDF placed in the schematic category.

The 140 KB PDF is identified only by the transistor number 2SC3393 and contains no board or model reference.

Part number 2SC5354 is all the name reveals about this 129 KB PDF, so it is not tied to any identified device.

For the 2SC5315, a JIS-coded NPN bipolar transistor, this 126 KB PDF is indexed as a schematic but most probably holds the component datasheet.

Covering the 2SC3150 transistor, this 103 KB PDF sits in the schematic category of the index.

Brief 41.4 KB PDF for the 2SC3117, which JIS numbering identifies as an NPN bipolar transistor.

Document for the 2SC3076 transistor, a 190 KB PDF indexed among schematics. The name offers no detail beyond the part number.

A 145 KB PDF labelled only 2SC2839, catalogued under schematics. The JIS 2SC prefix indicates an NPN bipolar transistor, so this is most likely a datasheet rather than a…

Small 42.4 KB PDF for the 2SC2634, carrying an _E suffix that may mean an English edition, though the name does not state it.

Filed as a schematic, this 52.9 KB PDF is named after the 2SB1668, a PNP bipolar transistor according to Japanese JIS numbering; the contents should therefore be its…

PDF datasheet of about 175 KB for the 2SB1555, a PNP bipolar transistor under the Japanese JIS 2SB numbering for low-frequency devices.

Reference PDF covering the 2SB1530 transistor, filed under schematics but in practice a component datasheet identified only by its JIS part code.

Short PDF of 38.2 KB covering the 2SA1635, a part number that follows the Japanese JIS scheme where 2SA identifies a high-frequency PNP bipolar transistor.

The 2SA1587 transistor is the subject of this 323 KB PDF, the largest in this group and likely to include detailed characteristic graphs.
