PCB drawing combined with a functional block diagram for the Xiaomi Mi 4S, provided as a 4.86 MB PDF.

Component documentation for the 2SC4269 in PDF form, 108 KB in size, listed in the schematic category. Nothing beyond the part number appears in the name.

A 305 KB PDF for the 2SC4246 transistor. The name states nothing apart from the part number, so the manufacturer and revision have to be read inside the document.

Datasheet-style PDF, 96.2 KB, named only for the 2SC3089 and catalogued as a schematic.

Here is a 122 KB PDF for the 2SA1696, a semiconductor numbered under the Japanese JIS system and listed among schematics, though a part-coded file like this is normally…

A 55.0 KB PDF titled with the 2SA1531 part number and an _E suffix, catalogued as a schematic yet most plausibly the datasheet for that transistor.

PNP transistor documentation for the 2SA1150, provided as a 193 KB PDF. JIS naming uses 2SA for PNP bipolar devices, so although indexed as a schematic the file almost…

Technical document for the Nuvoton NCT6776F Super I/O controller, a 3.75 MB PDF that, despite being catalogued as a schematic, is most likely the chip datasheet.

Reference document for the 2SC3112 transistor, supplied as a 257 KB PDF and filed under schematics. The name holds only the part number.

Small 42 KB PDF for the 2SC3077, filed as a schematic. The trailing _E in the name is not explained by the file name itself.

An 84.6 KB PDF for the 2SC3071, filed as a schematic. The name supplies nothing beyond the part number, so this is probably a compact datasheet.

An 89.5 KB PDF for the 2SA1590 transistor, listed under schematics but almost certainly a part datasheet given the name.

Small 21.4 KB PDF for the 2SA733 PNP transistor, with the UTC tag in the name pointing to the Unisonic Technologies version of this widely used general-purpose part.

The 1SS392 is documented in this 69.6 KB PDF, categorised as a schematic. Because 1SS is the Japanese numbering for small-signal silicon diodes, the file is most likely…

Spanish PDF numbered topic 5 on disassembling mobile terminals, roughly 954 KB, part of a phone repair training series. It does not name a specific handset.

Sheet metal drawing for the subwoofer 7294 project, version 1.1, a small 23.7 KB PDF; blacha is Polish for sheet metal.

Matrix 1.4 amplifier design in BTL configuration, meaning bridge-tied load where two amplifier halves drive the speaker in opposite phase, as a 1.76 MB PDF.

PDF amplifier circuit built around the Sanyo STK412-170 hybrid module, rated at 180 W in the name, which also marks it as OK, presumably a verified design.

Component distribution diagram for the iPhone 11 Pro Max, packed as a RAR archive and filed as schematic material.

Schematics for the Samsung SM-A307 handset, the Galaxy A30s series, packed into a 7.05 MB RAR archive.

Small 31 KB PDF schematic of an IO board for a project code-named Michigan, version A01 with a 0312 tag, probably a date.

Service manual in PDF for the Samsung SM-A115M, the Latin American Galaxy A11, about 21.8 MB, credited by name to Anibal Garcia.

PDF from Maxim Integrated covering the 8731AE, listed as a schematic but most likely the datasheet for that Maxim part.

Samsung E1200i schematic supplied as a small 707 KB PDF. The name lists only the model, a basic feature phone, and no board revision.

Nokia 3250 schematic, version 1.0 according to the name, provided as a 754 KB PDF. This handset is known for its twisting keypad section, and the diagrams help follow…

Small 46.2 KB PDF for the 2SC5501. Under the Japanese JIS scheme, a 2SC prefix marks an NPN transistor intended for high-frequency use.

Covering the 2SC5028, this 219 KB PDF is filed as a schematic yet is named like a component datasheet.

Small 41.6 KB PDF for the 2SC5388, a JIS-numbered NPN bipolar transistor; the file name states only the part number, so package, maker and application are not given.

PDF reference for the 2SC3596, sized at 119 KB and indexed with schematics although it describes a single semiconductor.

Small 39.6 KB PDF containing the datasheet for the 2sb1616, catalogued as a schematic entry.

Catalogued as a schematic, this 40.7 KB PDF is named after the 2SA1540, a Japanese JIS-registered transistor part number, so it is most likely the component datasheet.

Reference sheet for the 2SA1421, supplied as a 92.5 KB PDF and listed in the schematic category although the name points to a single semiconductor rather than a whole…

Version of the 2N5401 high-voltage PNP transistor datasheet tagged Sam in the name, a 53.3 KB PDF.

Indexed as a schematic, this 44.4 KB PDF named 180nq has the form of a power diode part number, pointing to a datasheet for a Schottky rectifier module series rather…
