The 2SD1907 is covered by this 165 KB PDF, which is catalogued as a schematic but by name is a component datasheet.

A 55.2 KB PDF named after the 2SK2348, a JIS-registered type whose 2SK prefix indicates an N-channel FET.

The 2SK427 document is a 226 KB PDF filed as a schematic, but the 2SK prefix marks an N-channel field-effect transistor in the JIS numbering scheme, so it is effectively…

A 140 KB PDF named after the semiconductor 2SJ563, listed in the index under schematics.

Datasheet-style document for the 2SJ537, delivered as a 137 KB PDF though indexed as a schematic.

The name of this 97.3 KB PDF gives nothing beyond 2SJ277, a JIS-style designation in which 2SJ marks a P-channel FET.

Named simply 2SJ226, this 84.5 KB PDF refers to a JIS-registered P-channel FET and most likely contains the part datasheet, even though it sits in the schematic section.

Schematic set for the Xiaomi POCO M3 in PDF form, packed inside a 4.20 MB RAR archive. Once extracted it opens in any PDF reader and lets a technician search for net…

For the 2SC4742 transistor, this 32.2 KB PDF is indexed under schematics yet appears to be a component reference.

An 88.2 KB PDF carrying only the part number 2SC4125, filed as a schematic though it is most likely a component datasheet.

A PDF document for the 2SC4884, filed under schematics but by its name a component datasheet rather than a board diagram.

PDF of 61.5 KB for the 2SA1870, with a 1-2 tag in the name. That tag may indicate one part of a split document or a revision, but the name does not say which.

PDF, 52.3 KB, documenting the 2SA1177, a PNP bipolar transistor in the JIS 2SA numbering scheme.

A compact PDF of 48 KB filed under schematics, named after the part 2PB1219A with a trailing 3 that probably marks a document issue.

Short PDF, 26.4 KB, named 2pg301 and placed in the schematic category alongside related 2pg files.

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.

Zener diode datasheet covering the range from 1N4728A to 1N4764A, an 88.2 KB PDF. This 1 W axial Zener series spans a wide range of nominal voltages, each part number…

A 54.5 KB PDF filed as a schematic and identified only by the short code 51HQ, with no brand, model or revision stated.

Indexed as a schematic, 36mt is a 53.9 KB PDF whose name is only a short code that resembles a component series designation rather than a laptop board number.

A compact 75.6 KB PDF indexed as a schematic but named 31DQ09, a code that looks like a rectifier diode part number, not a motherboard.

Filed as a schematic, this 75.4 KB PDF named 30TPS16 reads like a power semiconductor part number rather than a board layout, so it is most likely a component datasheet.

PDF filed as a schematic, named 28LV65, a code in the family of low-voltage parallel EEPROM memories.
