Apple iPad schematic, 1.26 MB PDF, whose name says full schematic but does not specify the generation or board number.

Schematic PDF of 1.6 MB named only Y300, which most likely refers to a Lenovo IdeaPad Y300-series device, though the name does not state the brand or board number.

Nokia N91 music phone schematics in a 2.27 MB PDF. The name does not state a board code or revision, so confirm the PCB markings against the document before relying on…

PDF schematic for the Quanta QL6 board, labelled DV2 and DIS, which most likely denotes the design-verification stage and a discrete graphics variant; the 0226 token…

PDF guide in Spanish on the power-on sequence of the Xiaomi Poco X3 Pro, covering stages one, two and three of startup.

PDF schematic for the SM6375 chip, carrying an SM63 family suffix in its name and measuring 1.51 MB. The handset or board it came from is not given.

Schematic in PDF, 1.96 MB, centred on the SM7150 processor according to its name; the phone model and board revision are not stated.

Datasheet-style document for the 2SD2581 transistor, saved as a 43.7 KB PDF and filed in the schematic category.

The name offers nothing beyond the 2SD2500 part number, and the 250 KB PDF is almost certainly that transistor's datasheet.

Transistor documentation for the 2SD1667, 136 KB in PDF format. Nothing beyond the part number appears in the name.

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 2SD1511 NPN transistor is the subject of this 56.9 KB PDF, filed under schematics in the index. JIS numbering assigns 2SD to low-frequency NPN bipolar parts.

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

PDF documentation for the 2SK1731 discrete semiconductor, roughly 90 KB in size. Japanese 2SK numbering identifies it as an N-channel FET; the name says nothing about…

Datasheet-type file for the 2SK1464 N-channel field-effect transistor, 120 KB in PDF form and indexed as a schematic.

Covering the 2SK1435, this 105 KB PDF is indexed as a schematic yet named after one discrete component, which suggests a datasheet.

Reference sheet for the 2SK937 transistor, a 79.9 KB PDF. Parts in the 2SK range are N-channel field-effect transistors under the Japanese JIS designation.

Here is the 2SC5242 documentation as a 173 KB PDF, placed in the schematic category but evidently a part datasheet going by its name.

Component reference for the 2SC3963, supplied as a 193 KB PDF in the schematic category.

A 100 KB PDF reference for the 2SC4919 transistor, catalogued as a schematic. The 2SC prefix follows the JIS convention for NPN bipolar transistors; manufacturer and…

Reference PDF covering the 2SB1530 transistor, filed under schematics but in practice a component datasheet identified only by its JIS part code.

Reference for the 2SA1497 transistor in an 88.3 KB PDF, catalogued as a schematic. The JIS 2SA prefix marks it as a PNP device.

Data sheet style PDF, 95.9 KB, named for the 2SA1470 and indexed as a schematic. The 2SA prefix under the Japanese JIS scheme identifies a PNP bipolar transistor.
