The 2SK545 is covered by this 80.4 KB PDF, filed as a schematic but most likely a datasheet because 2SK numbers identify N-channel field-effect transistors in the…

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.

A compact 44.5 KB PDF labelled 2SJ520 and catalogued as a schematic. Because 2SJ is the JIS prefix for P-channel FETs, the document is best treated as a short datasheet…

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

Only the part number 2SJ275 appears in the name of this 97.0 KB PDF. That code follows Japanese JIS numbering, where 2SJ indicates a P-channel field-effect transistor…

Filed as a schematic, this 93.5 KB PDF is identified solely by 2SJ274. The Japanese JIS 2SJ prefix stands for a P-channel field-effect transistor, so the content is most…

Named after the JIS part number 2SJ267, this 91.8 KB PDF most likely documents a P-channel field-effect transistor, since the 2SJ prefix denotes that device class.

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.

PDF reference, around 129 KB, covering two power ICs identified by marking codes: Qq for the SY8386BRHC and 3a for the SY8388C3RHC.

An archive in RAR format, roughly 959 KB, for the Xiaomi Mi 4S phone. The name lists only the model, with no indication of document type, PCB number or revision, so…

An archive for the original Xiaomi Mi 1, in RAR format of about 518 KB. Nothing beyond the model is given in the name: no board number, revision or content type.

Meizu MX5 archive in RAR format, 881 KB, whose name identifies only the phone model and not the file type inside.

A ZIP package of 309 KB labelled for the Lenovo A510 phone. Apart from the model name nothing reveals what is inside, so treat it as unverified repair data until…

Boardview in BVR format for the iPhone 5C main logic board, 266 KB uncompressed. It opens in boardview software that reads BVR files and shows both sides of the PCB with…

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

Indexed as a schematic, this 79.2 KB PDF is named 2SC4400 and should be the reference datasheet for that NPN bipolar transistor.

Listed under schematics but named only after a part number, this 91.6 KB PDF most likely holds the datasheet for the 2SC4188 transistor.

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

The 2SC4121 part number is the whole name of this 89.5 KB PDF; although typed as a schematic, it should be the datasheet for that NPN bipolar transistor, as the Japanese…

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

The 2SC5777 is covered by this small 29.9 KB PDF, catalogued as a schematic but most likely a single-part datasheet.

PDF of 37.3 KB named after the 2SC5406 and listed as a schematic, though it is almost certainly a component datasheet.

Part documentation for the 2SC5302 in PDF form, 89.2 KB, placed in the schematic section of the index.

A brief 48.3 KB PDF on the 2SC3504, catalogued as a schematic but containing transistor data.

Compact 49.5 KB PDF for the 2SC3354, with an _E suffix in the name that may indicate an English-language edition, though the name does not confirm it.

Filed under schematics, this compact 39.7 KB PDF is named after the 2SB976 part number, a Japanese JIS-style designation where the 2SB prefix marks a PNP transistor…

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.

The 2SA1734 is the subject of this 183 KB PDF, which carries only the component number in its name.

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 document, 47.9 KB, whose name points to the component 2PB710A, with the suffix 6 likely indicating a revision of the sheet.

PDF of 25.8 KB carrying only the code 2pg302 in its name and filed under schematics. No laptop model, board number or manufacturer is stated, so the content cannot be…

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

PDF of 47.7 KB named 2PD602A, apparently issue 4 of the document. The name identifies a part rather than a product or board, which points to a discrete semiconductor…

PDF of 168 KB filed as a schematic and named 2N2219A, a designation in the JEDEC 2N numbering used for discrete semiconductors.

A small 26.9 KB PDF in the schematic category, named only with the part number 2N6519 from the JEDEC 2N registration series.

Reference sheet in PDF form covering the 1SV214, filed under schematics although at 75 KB it reads like a single-part data sheet.

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.
