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…

Reference sheet in PDF form for the 2SA1593 transistor, 156 KB in size. The name gives only the part number, with no device or board details.

The 2SA1572 transistor is documented in this 49.4 KB PDF. No board or equipment model appears in the name, so treat it as a component datasheet.

Part documentation for the 2SB1287 in a 63.5 KB PDF; the 1-2 in the name probably marks pages one and two of the sheet. No device or board details are included.

Datasheet PDF for the 2SB1274, 34.4 KB in size and likely a concise sheet. The name offers only the part number.

Reference sheet for the 2SA1421, supplied as a 92.5 KB PDF and listed in the schematic category although the name points to a single semiconductor rather than a whole…

Small 37.6 KB PDF for the 2SA1900, written in lowercase in the original name and placed in the schematic category; the content is most likely a brief datasheet.

PDF document for the 2SA1200, a part number in the Japanese JIS 2SA series, which designates PNP bipolar transistors.

Small 41.8 KB PDF for the 2SA1890, with an _E suffix in the name that commonly marks an English-language edition of a Japanese datasheet, though the file does not…

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…

PDF document of 47.8 KB listed as a schematic and named 2PC1815, issue 3 by the trailing number.

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…

A 177 KB PDF for the JEDEC part 2N5655, carrying an RE suffix whose meaning the name does not explain.

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.

A 46.1 KB PDF datasheet covering the 2N3019 transistor, indexed in the schematic category.

A 292 KB PDF datasheet for the 2N2369, with an extra RE suffix in the file name whose meaning is not stated, catalogued as a schematic.

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.

Filed as a schematic, 1SV231 is a 68.1 KB PDF named after a component code; the trailing underscore is not part of it.

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

A short 31 KB PDF for the 1SV316 diode, filed in the schematic category. A separate entry with UV and sot323 tokens also exists for this part number, so compare both if…

Documentation for the 1SV312 part in PDF form, roughly 72 KB and classed as a schematic.

Reference sheet for the 1SV267 semiconductor, stored as a 63.1 KB PDF and filed under the schematic category.

Component reference for the 1SS401, stored as a 77.2 KB PDF under the schematic type. The name holds just the part number, so this is most likely a manufacturer…

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.

Catalogued as a schematic, this 69.5 KB PDF is named after the part number 1SS381, so it is most likely a component data sheet.

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.

The name 1SS360F gives a small-signal silicon diode number, per the JIS 1SS prefix, followed by an F suffix whose meaning the name does not state.

A compact PDF of 53.8 KB indexed as a schematic, named only after the part number 1SS350.

A small 68.0 KB PDF whose name holds only the component code 1SS337, with no brand, model or board number given.

Larger than most of its neighbours at 123 KB, this PDF is named only 1SS313 and gives no device or board details.

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.

Part code 1SS302 is the sole detail in this 67.5 KB PDF name; no laptop model, board number or revision is stated.

Here is a compact 73.3 KB PDF whose name, 1SS250, identifies a discrete part instead of a board, so treat it as a component datasheet despite the schematic label.
