Samsung SM-F731B schematic package, ZIP of about 3.42 MB, with the BE token in the name not otherwise explained.

PDF document named after the MSI-style board code MS36631-ZC01-01; no device model or brand appears in the name itself.

Specifications for the 2SK1611 in a 36.3 KB PDF document. Japanese 2SK numbering places this part among N-channel FETs, and the name offers no further detail such as…

Part datasheet for the 2SC4484, a 134 KB PDF. Japanese JIS numbering uses 2SC for NPN bipolar transistors, which identifies the device class here; nothing else is given…

Samsung SM-A136B service schematic, which corresponds to a Galaxy A13 5G variant, packed in a ZIP file of around 11.3 MB.

Apple logic board schematic for project X502, MLB codename CATZ, board number 820-00875, with schematic number 051-02265 at revision 1.0.0.

PDF for the IRF540 MOSFET, and the name indicates the datasheet comes from Philips. Although listed under schematics, the 91.6 KB file is a component sheet with ratings…

Datasheet for the 2SD2258 NPN bipolar transistor, supplied as a 56.8 KB PDF and filed under schematics.

Covering the 2SD1817, this 75.8 KB PDF is indexed as a schematic but by name is a component datasheet. No maker or revision is indicated.

For the 2SD2098 transistor, this 159 KB PDF is categorised as a schematic but follows the usual naming of a part datasheet.

Labelled 2SD1997, this 86.1 KB PDF is indexed as a schematic, yet a bare transistor part number points to a manufacturer datasheet.

Datasheet-style PDF for the 3LP02N, about 41.5 KB and listed as a schematic. No device, brand or board details appear in the name beyond the part code itself.

Datasheet-style PDF for the 2SD1994A transistor, filed in the schematic category of the index.

Datasheet PDF, 43.0 KB, for the 2SD2321, with an _E suffix carried over from the original name, though the suffix itself is not explained.

The 34.0 KB PDF named 2SK3557 is indexed as a schematic, but its name is a JIS component number, so it is almost certainly a datasheet.

The 2SK2792 part number appears here with an unexplained 1-5 suffix, possibly a page range or edition marker.

Here the 2SK2746 is documented in a 420 KB PDF, categorised as a schematic yet named like a single-part datasheet.

Covering the 2sk2580, this 34.5 KB PDF is labelled a schematic yet identifies only a semiconductor part, pointing to a short datasheet.

The 2SK2545 is the subject of this 415 KB PDF, catalogued as a schematic but by its name a discrete transistor document.

PDF for the 2SK2463 carrying a _1-5 suffix, 136 KB in size; the name does not explain the suffix, which may refer to pages or an edition of the document.

PDF reference for the 2SK2339 transistor, 35.9 KB, catalogued under the schematic type.

Short PDF of 23.2 KB named for the 2SK2324 part. In JIS nomenclature 2SK denotes an N-channel FET, so this schematic-labelled file is presumably a brief datasheet.

The 2SK2010 transistor is documented in this 90.1 KB PDF, filed among schematics but in substance a datasheet for an N-channel FET, as the JIS 2SK prefix indicates.

Part-number PDF for the 2SK1471, 92.5 KB in size and labelled as a schematic in the index.

The 2SK1375 N-channel field-effect transistor is covered by this 150 KB PDF, filed under schematics in the catalogue.

Component sheet for the 2SK1069, an N-channel FET from the Japanese 2SK numbering range, stored as a 98.7 KB PDF.

The 2SJ511 named in this 417 KB PDF is a JIS-coded semiconductor, the 2SJ prefix signalling a P-channel field-effect transistor.

PDF document for the 2SJ346, filed in the index as a schematic but named after a discrete semiconductor part.

Small 89.2 KB PDF labelled 2SJ191, a JIS designation that marks a P-channel FET, so the file is presumably that part's datasheet rather than a board schematic.

An 82.4 KB PDF bearing only the part number 2SJ188; the 2SJ prefix in Japanese numbering denotes a P-channel field-effect transistor, so this is likely its datasheet…

The 2SC4690 is the subject of this 175 KB PDF, which the index files as a schematic even though the name points to a single transistor document.

Here is a 42.3 KB PDF for the 2SC5264LS, indexed as a schematic. JIS numbering makes the 2SC prefix an NPN bipolar transistor, and the LS letters identify a variant of…

A 161 KB PDF carrying only the part number 2SC4650, a JIS-registered NPN transistor. Nothing in the name links it to a specific device, so treat it as a component…

A 39.6 KB PDF for the 2SC5216, with an _E tag in the name that is not explained. It is listed as a schematic, but the name points to a transistor datasheet.

Datasheet-style PDF of 88.2 KB for the semiconductor 2SC4475, catalogued in the schematic section.
