PDF of 46.9 KB filed under schematics but named after the component 2PC4617, with a suffix 3 that likely denotes the document issue.

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

Compact PDF, 45.7 KB, named 2N2102 and catalogued under schematics. The 2N prefix belongs to the JEDEC scheme for discrete semiconductor parts, so the document is most…

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 61.0 KB PDF for the 2N4125 part number, the plain-named counterpart to an RE variant also present in the index.

Here the 2N4123 is covered by an 83.6 KB PDF, the plain-named version alongside an RE-suffixed file for the same number.

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

PDF datasheet of 73.0 KB for the 2N2906 transistor, stored in the schematic section of the index.

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.

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

A PDF document for the 1SV215 part, catalogued as a schematic but most likely a component data sheet.

Documentation for the 1SV172 diode, stored as a 72 KB PDF and indexed as a schematic. The 1SV numbering is a Japanese JIS diode designation that Toshiba applies to…

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

PDF document for the 1SV304 semiconductor part, filed under schematics in the index at 71.0 KB.

A small PDF of 69.9 KB, listed under schematics and titled with the part number 1SV268.

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

A 61.3 KB PDF for the 1SV250, placed in the schematic category by the index. Following Toshiba's numbering, the 1SV group covers variable-capacitance diodes, so expect a…

Component document for the 1SS133, catalogued as a schematic but most likely a datasheet for a small-signal diode, since the 1SS prefix is the Japanese JIS-style…

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.

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

Only the part number 1SS336 appears in this 68.3 KB file name, and the PDF is filed under schematics.

The 69.8 KB PDF here is labelled with nothing more than 1SS321, a part number in the Japanese small-signal diode designation used largely by Toshiba.

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.

Despite the schematic tag, this 50.3 KB PDF named 1N755A is a datasheet for a JEDEC-registered diode; the 1N746A to 1N759A range is a well-known zener series.

Named for the 1N754A, this 50.3 KB PDF is a component datasheet from the JEDEC 1N zener series that runs from 1N746A to 1N759A, even though it is indexed as a schematic.
