Schematic PDF named only T135, around 768 KB, with no brand listed. It may relate to the Toshiba Satellite T135, but the name alone cannot confirm that, nor any board…

Schematic PDF for the Bitland BM5688 board, a design from the ODM Bitland, which builds laptops and tablets for various brands.

Small 57.3 KB PDF for the 2SC5060, filed under schematics though the name suggests a transistor part sheet.

Part sheet in PDF form, 29.1 KB, for the 2SD2646 transistor, filed in the schematic category. The name supplies only the type number, without brand or revision.

At 312 KB, this PDF for the 2SD2638 is the largest in its series and is probably a full datasheet with curves and outline drawings, though it is filed under schematics.

Filed under schematics, the 39.8 KB PDF 2SD2441 with an E tag refers by its JIS-style 2SD prefix to an NPN bipolar transistor.

A 166 KB PDF for the 2SD1904 transistor, listed here as a schematic but by its name almost certainly the manufacturer data sheet.

A 365 KB PDF for the 2SK2859, filed under the schematic type though it is most probably a manufacturer datasheet. Nothing other than the part number appears in the name.

A compact 134 KB PDF titled with the part number 2SK2839 and catalogued as a schematic.

Datasheet-type PDF for the 2SK2740, 138 KB, with a 1-5 suffix in the name whose meaning is not stated, possibly an edition or page range.

A 416 KB PDF covering the 2SK2610, a JIS-designated part whose 2SK prefix identifies an N-channel FET.

Short datasheet-type PDF of 30.0 KB for the 2sk2588, an N-channel FET according to the JIS 2SK prefix.

Documentation for the 2SK2036 in a 326 KB PDF. Parts beginning with 2SK are N-channel field-effect transistors under the Japanese JIS numbering, so this file should be…

A 34.3 KB PDF for the 2SK1846 transistor. The 2SK prefix follows the Japanese JIS convention for N-channel FETs, so this is probably a part datasheet even though it is…

2SK1841 documentation in PDF form, 90.4 KB in size and listed as a schematic. The 2SK designation in the Japanese JIS system indicates an N-channel FET, so expect…

The 2SK1839 is covered in this 84.9 KB PDF, filed under schematics though the name points to a single semiconductor part.

An 88.5 KB PDF on the 2SK1738 transistor. In the JIS system, 2SK designates an N-channel FET, so this file is most likely the datasheet rather than a circuit schematic.

Datasheet document for the 2SK1103 transistor, filed as a 29.5 KB PDF. Parts beginning with 2SK are N-channel field-effect transistors registered under the JIS scheme…

Bearing only the part code 2SJ438, this 416 KB PDF is indexed as a schematic, yet the 2SJ prefix in Japanese JIS designation identifies a P-channel field-effect…

Nothing beyond the code 2SJ272 is given in the name of this 92.3 KB PDF. Japanese JIS numbering assigns the 2SJ prefix to P-channel field-effect transistors, so the…

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.

A 177 KB PDF describing the 2SC4689, placed in the schematic category of the catalogue.

Part-number reference for the 2SC4433 in PDF form, about 71.5 KB. The name gives no board or device, only the JIS designation, where 2SC denotes an NPN bipolar…

PDF for the 2SC4417 carrying an _E suffix whose meaning the name does not explain, sized 40.7 KB.

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

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

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

Only the part number 2SC4168 identifies this 150 KB PDF, which carries a schematic label but is almost certainly a component datasheet.

Larger than most in this series at 474 KB, this PDF is for the 2SC5084, an NPN bipolar transistor according to the JIS 2SC prefix, catalogued here as a schematic.

The 2SC5540 transistor is covered by this 30.9 KB PDF, catalogued as a schematic. By JIS convention the 2SC prefix signifies an NPN bipolar device, so the document is…

Covering the 2SC5028, this 219 KB PDF is filed as a schematic yet is named like a component datasheet.

PDF document of 90.2 KB titled with the part number 2SC3995 and filed as a schematic. The 2SC prefix follows JIS naming for NPN bipolar transistors; the name gives no…

At only 24.2 KB, the 2SC3989 PDF is a compact document, probably a short datasheet or summary page for this JIS-numbered NPN bipolar transistor despite being indexed as…

Datasheet-style PDF for the 2SC3988, 114 KB, filed in the schematic category though the name is a plain JIS transistor number.

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