iPhone X schematic in PDF format, 1.23 MB, tagged with a contributor handle in the name.

The name 2SC4172 is a Japanese JIS semiconductor designation, so this 109 KB PDF, though filed as a schematic, should be the reference sheet for an NPN bipolar…

Part number 1SS379 is the only detail in this file name, and the 70.0 KB PDF is most likely the specification sheet for that diode rather than a full device schematic.

Covering the 2SC4612, this 155 KB PDF is indexed as a schematic but is in practice a transistor datasheet, as only the part number appears in the name.

The 2SD2201 is the subject of this 153 KB PDF, indexed as a schematic though the content is presumably a datasheet.

Reference sheet in PDF format, 101 KB, for the 2SC4852 NPN transistor, named under the Japanese JIS convention where 2SC denotes NPN bipolar parts.

The 10BQ040 sheet, an 85 KB PDF indexed as a schematic, belongs to a surface-mount Schottky rectifier family in International Rectifier style numbering.

ASUS K42Jv laptop schematic in PDF format, 1.41 MB in size. No board number or revision is given in the name, so read the title block and compare it with the silkscreen…

Listed in the schematic category, this small 105 KB PDF is in practice a component document for the 2SD1064 part.

Indexed under schematics, this 96.2 KB PDF is named for the semiconductor 1SS356 and nothing else.

Named simply 1N821, this 34.4 KB PDF follows JEDEC 1N diode numbering and is most likely a single-part datasheet, not a circuit diagram, even though it sits in the…

Schematic in PDF for the ASUS K52N laptop, revision 1.0, around 1 MB in size. No motherboard code is named, so check the revision and markings on the PCB match before…

Component datasheet for the 2SB1434 transistor, filed under schematics but in practice a part reference rather than a board diagram.

Reference PDF for the 2SD1065, 119 KB, filed in the schematic category although the name identifies a single transistor and points to a datasheet.
