MSI EX600 notebook schematic, board MS-1636 revision 1.1, in a 1.10 MB PDF. MSI designs its own laptop boards, and MS-16xx codes identify the mainboard; check that the…

Laptop schematic for the Lenovo IdeaPad 110-15ISK, built on the Compal LA-D562P motherboard, revision 2.0.

PDF schematic identified only as A01, apparently a smartphone model designation, with no brand, board number or revision given in the name.

Small PDF of 92.1 KB filed under schematics, though its name is simply the part number 2SD1998, so it is almost certainly a component datasheet rather than a 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.

PDF of about 295 KB for the 2SK1827. In JIS part numbering, 2SK stands for an N-channel FET, so the content should be a datasheet rather than a board-level drawing.

Reference sheet for the 2SK1109, with the name indicating the UTC (Unisonic Technologies) version of the part.

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…

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.

Compact 102 KB PDF for the 2SC3090 transistor, indexed under schematics. The name carries no detail beyond the part code.

A 41.1 KB PDF titled with the part number 2SC1980 and an _E suffix, catalogued among schematics.

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

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

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.

Covering the 1N5396 diode, this 42.7 KB PDF is a manufacturer datasheet rather than a board schematic, despite its category.

Datasheet for the 1N4454 diode, a very small 19.5 KB PDF that probably holds a short single-page summary.

Datasheet in PDF form, 23 KB, for the 1N4154 small signal switching diode. The name holds no further details such as vendor or revision, so those must be read from the…

A 95 KB PDF filed under schematics and labelled simply 124nq, without a voltage suffix, board number, revision or product name.

The 1SR156-400 document is a 120 KB PDF catalogued as a schematic, though its name follows a discrete component part-number style and carries no device or board…

A 72.8 KB PDF indexed as a schematic and titled 110mt080kb, a code in a component part-number style with no reference to any laptop, board number or revision.

Indexed as a schematic, the 104mtkb document is a 159 KB PDF whose name follows a power semiconductor series style with no voltage suffix, device model, board number or…

Indexed as a schematic, this 154 KB PDF covers a range named 1SMA5913BT3 to 45BT3, which follows the naming of an SMA-package Zener diode series.

A short 64.3 KB PDF titled after the 1KAB-E series, catalogued as a schematic but by its name more likely a datasheet covering a family of discrete components such as…

Short PDF of 54.6 KB labelled 60HQ and indexed as a schematic. Apart from that series-style code, the name carries no device, brand, revision or version information.

A 143 KB PDF titled 30CPU04, a part-number style name suggesting a single component datasheet even though it is catalogued as a schematic.

A 176 KB PDF listed as a schematic and named 20ETS08S, with no device, board number or revision given.

English PDF on testing electronic components, filed under schematics but in practice a general reference rather than a circuit diagram for a particular board.

Audio schematic for the Samsung SM-A21s covering microphone, loudspeaker and earpiece, PDF, 3.82 MB.

Samsung SM-A21s fingerprint reader schematic, delivered as a 3.82 MB PDF. The page documents the fingerprint sensor circuit, generally the connector, supply and…

Audio section of the Samsung SM-A11 schematic covering the microphones, loudspeaker and earpiece, as a PDF of 4.33 MB.

BM5070 schematic as a 2.45 MB PDF, with the name giving only this code and no brand, model or revision.
