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…

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 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.

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.

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…

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…

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

A 41.3 KB PDF named 2SC5018 with an additional _E suffix that the name does not explain.

Part reference for the 2SC4987, provided as a 110 KB PDF and filed under schematics. No model, board or revision is stated in the name.

Covering the 2SC3914, this 30.1 KB PDF belongs to the family of JIS-numbered NPN bipolar transistors identified by the 2SC prefix.

A 179 KB PDF for the 2SC3670, an NPN bipolar transistor by its JIS-style 2SC prefix. The name gives only the part number, with no device, board or revision, so treat it…

A 106 KB PDF for the 2SC3143, which the JIS 2SC designation marks as an NPN bipolar transistor.

Catalogued under schematics, this 51.3 KB PDF is named after the 2SC1473, which by the Japanese JIS convention is an NPN bipolar transistor, so it is most likely a…

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…

Datasheet-style PDF for the 2SA1858 semiconductor, catalogued here under schematics, with an _E suffix in the name that likely marks an alternate edition of the…

A 296 KB PDF identified only by the JEDEC-style part code 2N5769. The catalogue lists it as a schematic, yet the name points to a single discrete semiconductor, so its…

Listed under schematics, this 188 KB PDF is named for the JEDEC part 2N5550 with an RE suffix whose meaning is unclear. No laptop, board code or revision is given.

2N5400 transistor datasheet marked Sam, a 56.9 KB PDF that probably originates from Samsung, although the name alone cannot prove it.

Reference sheet for the 2N4264, saved as a 264 KB PDF and carrying an RE tag in the file name that is not explained further.

Catalogued as a schematic, 1T407 is a compact PDF of 52.9 KB whose name contains only a component code. No device model, brand or board number is given.

Indexed under schematics, this 66.7 KB PDF is named 1SV225; the trailing underscore looks like a naming artefact.

A 98.0 KB PDF for the 1SS390, the largest of this group and filed as a schematic type. The name holds only the part number.

The name identifies only the part 1SS377, so this 69.8 KB PDF is best treated as a diode data sheet even though it is indexed as a schematic.

The file name gives the part number 1SS365 and nothing more, and at 49.2 KB the PDF is the size of a typical short component data sheet.

Nothing beyond the code 1SS309 appears in the name of this 69.5 KB PDF, so no device or board can be tied to it.
