PDF datasheet for the 4N35 optocoupler, marked as revision 2 in the file name and about 276 KB in size.

Named after the JIS designation 2SK184, this 307 KB PDF is tagged as a schematic but is most likely the device datasheet.

Datasheet-style PDF, 134 KB, for the 2SK2715, with a 1-5 suffix in the name whose purpose is not stated and may mark an edition.

The 2SK2605 is the subject of this 411 KB PDF, filed as a schematic although its name is purely a semiconductor part number.

Covering the 2sk2571, this 24.5 KB PDF is a short document classed as a schematic, though its name is just a part number and the content is likely a concise datasheet.

The 2SK2395 is covered in a compact 96.5 KB PDF, classified as a schematic but most likely a component datasheet.

The 2SK2015 is covered by this 33.1 KB PDF, which in practice is a datasheet for a Japanese-registered N-channel field-effect transistor, the 2SK prefix indicating that…

Brief 31.8 KB PDF for the 2SK1980, which by the JIS 2SK prefix is an N-channel FET. Although indexed as a schematic, the document is almost certainly a datasheet for…

The 2SJ316 is the subject of this 91.5 KB PDF. Its name gives only the semiconductor type code, so no equipment model can be inferred.

Reference datasheet in PDF format, about 133 KB, describing the 2SD826 transistor; the source manufacturer is not given in the name.

The name 2SC4705 refers to a Japanese JIS-numbered NPN transistor. This 102 KB PDF is therefore most likely the component datasheet, even though it is catalogued as a…

Component documentation for the 2SC4220, delivered as a 106 KB PDF and filed under schematics.

PDF of 250 KB on the 2SC941TM transistor, an NPN bipolar part in the Japanese 2SC series; the TM suffix is part of the name but its meaning is not stated.

The name refers to the 2SC5502, a part in the Japanese 2SC numbering family reserved for NPN bipolar transistors.

Largest of this group at 335 KB, the PDF covers the 2SC3120 transistor, an NPN bipolar part per the JIS 2SC designation.

A small 28.6 KB PDF, catalogued as a schematic, referenced by the transistor number 2SC2812N.

The 2SB906 transistor is the subject of this 196 KB PDF. Following JIS designation, 2SB parts are PNP bipolar transistors classed for low-frequency use.

PDF datasheet, 94.4 KB, for the 2N7002LT1, with rev2 in the name indicating the second revision of the document. It is filed as a schematic.

Only the part code 2N5657 identifies this 497 KB PDF, which the index lists under schematics.

Revision-tagged PDF of 116 KB for part 2N5460, the rev0x token apparently marking a document edition whose exact number is not given.

Indexed under schematics, this small PDF of 42.7 KB is labelled 1T404A. That is the A variant of the 1T404 part code, which is catalogued separately.

Part number 1SS312 is all this 123 KB PDF name reveals; no brand, laptop model or board revision is mentioned.

Indexed under schematics, this 70.4 KB PDF is named only 1SS308, without any laptop model, board number or revision.

Compact 31.4 KB PDF datasheet for a 1N4001 variant marked ID in the name, catalogued in the schematic section.

Labelled only 123nq, this 98.5 KB PDF is catalogued as a schematic but names no device, board or revision.

Titled simply 111ria, this 104 KB PDF is indexed as a schematic, though the name resembles a power semiconductor series code rather than a motherboard identifier.

Named 100BGQ015 and sized at 200 KB, this PDF is listed as a schematic but the part number fits a Schottky rectifier, so it is most likely the component datasheet.

Catalogued under schematics, the 121 KB PDF named 75HQ045 does not mention any laptop, brand or board number.

A 51.8 KB PDF identified only by the code 16YQ150C, listed under schematics. There is no device model, board number or revision in the name.
