A 648 KB PDF schematic covering the Acer Aspire 5332, 5732, 5732Z and 7715 family. The file name gives no motherboard number or revision, so check the title block inside…

Schematic for a Nokia phone listed as model 26110 in a 1.87 MB PDF. The number as written does not match a familiar Nokia model, so it may be a typo for another handset…

ThinkPad T60 schematic in a 1.63 MB PDF, with GM in the name most likely pointing to the 945GM chipset build with integrated graphics; no revision is stated.

Schematic diagram in PDF for the IBM ThinkPad R40, roughly 1.45 MB; the name gives no board number or revision.

Circuit diagram titled UX50, delivered as a 1.45 MB PDF. The name gives no brand, revision or full board number, so read the cover page to confirm which board it covers.

PDF schematic section for the SM6150 processor, also tagged SM61, about 1.26 MB, with no device model specified.

Component documentation for the 2SD2257 transistor, in PDF form at 180 KB. Although the index lists it as a schematic, the file name points to a single discrete part…

PDF datasheet, 40.9 KB, for the 2SD2240 transistor, filed under schematics in this index. An _E suffix in the name is an edition marker for the document only.

PDF of 75.0 KB covering the 2SD2176 part. Though listed as a schematic, a file named after a single JIS transistor number is most likely a datasheet, and the 2SD prefix…

Single-part PDF of 47.0 KB for the 2SD2583, listed as a schematic but most probably a datasheet.

Compact 42.8 KB PDF for the 2SD2537, listed as a schematic though the name points to a single-component datasheet.

This PDF of about 124 KB covers the 2SD2114 transistor with a KS suffix; the suffix is not explained by the name and may denote a gain class or package variant.

At 198 KB, the PDF for the 2SD1658 is one of the larger sheets in this group, though it still names only the part.

The 2SD1628 is covered in this 88.3 KB PDF, catalogued with schematics though it relates to a single transistor.

Indexed as a schematic, this 109 KB PDF is titled 2SD1621, a transistor part number, so treat it as a datasheet rather than a circuit diagram.

Component documentation for the 2SD1881 transistor, supplied as a 90.6 KB PDF and catalogued as a schematic, though a part number like this normally points to a…

PDF covering the 2SD1880, about 88.9 KB, listed as a schematic but named after a single semiconductor part.

Compact 43.6 KB PDF named for the 3N249 and filed as a schematic, although it is almost certainly a component datasheet.

The 3N248 is covered by this 43.6 KB PDF, indexed under schematics but named only by its JEDEC part number.

Largest in this set at 269 KB, the PDF 2SD2414 is catalogued as a schematic, yet its 2SD prefix marks an NPN bipolar transistor under the Japanese JIS scheme.

The name carries only a part number, 2SD1905, which points to a semiconductor datasheet even though the entry is filed under schematics.

Filed under schematics, though the file name is simply the JIS part number 2SD1903, so expect a component datasheet in this 131 KB PDF.

Datasheet-style PDF for the 2SK3018, indexed here under schematics, though the 2SK prefix marks a Japanese JIS-registered N-channel field-effect transistor rather than a…

PDF reference for the 2SK2825, 301 KB in size and listed in the schematic section. The 2SK designation, from the Japanese JIS numbering system, belongs to N-channel…

Brief 34.7 KB PDF for the 2sk2581 transistor, catalogued as a schematic. JIS naming assigns 2SK to N-channel field-effect transistors, and the name gives no further…

Part document for the 2sk2575, 35.2 KB in PDF format and catalogued as a schematic. The 2SK prefix in JIS nomenclature marks an N-channel field-effect transistor; the…

Reference sheet in PDF format for the 2SK2549 field-effect transistor, 373 KB in size. In the JIS numbering used by Japanese semiconductor makers, 2SK denotes an…

PDF documentation for the 2SK2544 N-channel FET, following the Japanese JIS 2SK naming pattern, with a file size of 409 KB.

The 2SK2504 transistor is documented in this 134 KB PDF, named in lowercase and catalogued under schematics.

Document for the 2SK2400, 403 KB in PDF format and listed as a schematic, although the name points to a single-component datasheet.

Datasheet-style PDF, 55.1 KB, for the 2SK2347 semiconductor, stored in the schematic section of the index.

For the 2SK2313 transistor, this 419 KB PDF is filed as a schematic but is expected to be a datasheet, since 2SK is the JIS prefix for N-channel FETs.

The 2SK2267 named here is an N-channel FET under the Japanese JIS/EIAJ scheme, where 2SK denotes that transistor class.

The file name gives nothing beyond 2SK2233, a JIS/EIAJ designation whose 2SK prefix marks an N-channel field-effect transistor.

Part number 2SK2231 is the only information carried by this 420 KB PDF, which the index places among schematics but which most likely documents a single transistor.
