The 2SD1294 is the only detail this 209 KB PDF name provides; the file is filed as a schematic but corresponds to a transistor part number.

Datasheet for the 2SD882 NPN transistor in a 165 KB PDF; the file name does not state which manufacturer issued it, unlike the UTC versions in the same set.

Specification PDF, roughly 32 KB, for the 2SD667 transistor, listed among schematics but in fact a component datasheet.

Catalogued as a schematic, this 41.7 KB PDF bears the part number 2SC5611 and should be the datasheet for that NPN bipolar transistor.

Indexed as a schematic, this 91.5 KB PDF named 2SC4390 is most likely the datasheet of that NPN bipolar transistor.

Filed as a schematic, this 464 KB PDF carries just the name 2SC4322 and should be read as a transistor datasheet.

Datasheet-style PDF for the 2SC4271 transistor, catalogued here under schematics and weighing 78.2 KB. The name gives only the part number, with no maker or revision.

A 107 KB PDF covering the 2SC4270, a JIS-numbered part. The 2SC prefix denotes an NPN transistor intended for high-frequency use.

PDF reference for the 2SC4257 transistor, 81.6 KB, filed under schematics although it is a part document rather than a board drawing.

Datasheet PDF for the 2SC5575, 52.0 KB, placed in the schematic section of the index. The file name contains only the part number.

Indexed as a schematic, this 296 KB PDF is named only 2SC5094, a JIS-style transistor designation where 2SC stands for an NPN device rated for high-frequency operation.

Component data for the 2SC5531 NPN bipolar transistor, supplied as a 51.5 KB PDF and catalogued under schematics.

Small 46.2 KB PDF for the 2SC5501. Under the Japanese JIS scheme, a 2SC prefix marks an NPN transistor intended for high-frequency use.

Covering the 2SC5019, this 41.9 KB PDF carries an _E suffix and is indexed as a schematic.

Datasheet PDF for the 2SC3931, 60.7 KB, with the _E suffix common to this group of files and listed as a schematic.

The 2SC3922 is the subject of this short 30.5 KB PDF, listed as a schematic with no suffix or revision in its name.

PDF of 41.0 KB titled 2SC4968 with an _E suffix whose meaning the name does not state. It is listed among schematics, but the 2SC prefix follows the JIS/JEITA…

Short 108 KB PDF datasheet for the 2SC3601, placed in the schematic section of the index.

PDF reference for the 2SC3596, sized at 119 KB and indexed with schematics although it describes a single semiconductor.

Data for the 2SC3576, an NPN transistor per the JIS 2SC designation, supplied as a 108 KB PDF and filed among schematics.

Covering the 2SC3547A, this 288 KB PDF is a transistor datasheet indexed in the schematic section.

For the 2SC3503, a 158 KB PDF datasheet listed with schematics. Only the part number is given; per the JIS system, a 2SC number belongs to an NPN bipolar transistor…

Datasheet-type PDF of 43.3 KB for the 2SC5335, with an _E suffix that may denote an English version, though the name does not state it.

Under the Japanese JIS scheme the 2SB726 is a PNP bipolar transistor, so this 39.6 KB PDF, though catalogued as a schematic, should be its datasheet; the _E suffix…

Component datasheet for the 2SB1644, a small 48 KB PDF catalogued under schematics. JIS numbering places any 2SB part among PNP bipolar transistors for low-frequency…

The 2SB1589 PNP transistor is described in this 40.1 KB PDF datasheet, with an _E suffix that most likely points to the English edition.

Small PDF document for the 2SB1537, a Japanese JIS-registered transistor part number, catalogued here as a schematic although a part code like this normally points to a…

PDF of about 39 KB for the 2SB1462J, a variant designation of the 2SB1462, with the _E suffix likely marking English text.
