Earlier revision 2.01 schematic for the Gigabyte GA-B85M-D2V motherboard, delivered as a PDF inside a ZIP archive.

Component placement drawing for Apple logic board 820-01055, a 228 KB PDF. Placement sheets map reference designators to physical locations, so you can find a capacitor…

Schematic in PDF form for the Samsung Galaxy A50, model SM-A505F. The name states no board revision.

PDF schematic for the ThinkPad T42 laptop, about 1.08 MB in size. No board revision or code name appears in the name, so check the system board label before matching…

Schematic document named V6J, about 2.13 MB in PDF format. The name supplies only this project code, with no brand, board number or revision, so the title block should…

Schematic for the Lenovo ThinkPad E560 with the BE560 project code, drawn for the NM-A561 motherboard at revision 1.0, in PDF format.

Component location map for the Xiaomi Mi 11 smartphone, part one of the set, as a PDF in an 860 KB RAR archive.

Schematic package for the Compal LA-5051P mainboard, revision 0.3, compressed to 977 KB in RAR format.

Large 28.2 MB PDF schematic for the Samsung Galaxy S4, model GT-I9505. The size suggests a fairly complete service document, likely including detailed circuit pages and…

A small 33.3 KB PDF covering the 2SD330 transistor, listed as a schematic though it documents a single discrete part. The name carries no other details.

Covering the 2SK2507, this 422 KB PDF belongs to the JIS family of N-channel field-effect transistors denoted by the 2SK prefix.

Reference PDF for the 2SK2466, 424 KB in size, belonging to the JIS N-channel FET family denoted by 2SK. The name contains only the part number.

PDF of 119 KB for the 2SD1207, categorised as a schematic though its name is a JIS transistor number.

The 86.7 KB PDF named 2SC4572 is filed as a schematic yet carries a transistor part number, so expect a component datasheet rather than a circuit diagram.

Reference PDF for the 2SC4869, 126 KB, sorted into the schematic category. Nothing else is given in the name.

PDF data for the 2SC3781 NPN transistor, roughly 128 KB in size, filed as a schematic though it is most likely a component datasheet.

Datasheet for the 2SC3757 NPN transistor, a 47 KB PDF whose _E suffix probably indicates the English-language edition.

Filed under schematics, this 99.9 KB PDF is named for the 2SC3038 transistor and probably contains its datasheet.

The 2SB1140 is covered by this 103 KB PDF, catalogued in the schematic section. Japanese JIS numbering assigns 2SB to PNP transistors meant for low-frequency service, so…

Brief 41.2 KB PDF for the 2SB1036, carrying an _E suffix that the name leaves unexplained.

Datasheet-type PDF of 197 KB for the 2SA2069 transistor, indexed under schematics. Following JIS naming, the 2SA prefix identifies a PNP transistor intended for…
