Datasheet-style PDF for the 2SK669, a part number in the JIS 2SK series used for N-channel field-effect transistors, listed in the index as a schematic.

Reference PDF for the 2SK620, a JIS-series N-channel field-effect transistor, weighing 35.6 KB and listed under schematics though it is most likely a datasheet.

At just 31.4 KB, the PDF named 2SJ499 is probably a short datasheet or summary sheet, even though it is filed as a schematic.

Catalogued as a schematic, this 93.1 KB PDF is named only after the part number 2SJ281, which follows the Japanese JIS scheme where the 2SJ prefix denotes a P-channel…

Samsung SM-A205F schematics, the Galaxy A20, provided as PDF files inside a RAR archive of about 4.06 MB.

Samsung SM-A127F repair archive in RAR format, about 2.29 MB, named only by the model code with no hint of its exact contents.

Compressed RAR archive, 5.12 MB, for the OPPO R11s smartphone. The name gives no more than the model, so contents such as schematics or a board layout have to be checked…

Archive for the Meizu M6, 3.02 MB in RAR format, with a name that gives the model but nothing about the document type.

ZIP archive of 1.46 MB for the original Apple iPhone, commonly called the iPhone 2G. The name states only the model, so the precise contents should be checked after…

Boardview in BVR format for the iPhone 6 logic board, 313 KB. It shows part placement, designators and nets for both sides of the PCB and opens in boardview software…

Archive named G973F, the model code of the Samsung Galaxy S10 international variant, packed as a 7.70 MB RAR.

Generic 25.4 MB RAR archive with the vague name hpp pc, which tells nothing reliable about its contents.

Small 31.3 KB PDF covering the 2SC5265LS, filed as a schematic. The 2SC prefix in the JIS system identifies an NPN bipolar transistor, and the LS suffix marks a variant…

Filed under schematics, this 98 KB PDF is named after the part number 2SC4671, which follows the Japanese JIS designation for an NPN bipolar transistor.

This 39.4 KB PDF is labelled 2SC4656 with an E suffix. The E most likely marks an English edition from a Japanese maker, but the name does not say so outright.

Small Excel spreadsheet of 12.0 KB whose name refers only to GDDR6X, the graphics memory type used on some modern video cards.

The name 2SC4172 is a Japanese JIS semiconductor designation, so this 109 KB PDF, though filed as a schematic, should be the reference sheet for an NPN bipolar…

The 2SC4163 part number is all this 98.9 KB PDF name reveals, so although labelled a schematic it is best read as a transistor datasheet.

Stored under schematics, this 93.8 KB PDF is named for the 2SC4123 and is expected to hold the transistor's datasheet rather than a circuit drawing.

Small 95.8 KB PDF for the 2SC4109, indexed with the schematics. The file name gives nothing beyond the part number; the 2SC prefix identifies an NPN bipolar transistor…

Small PDF of 25.0 KB dedicated to the 2SC4064, catalogued as a schematic. Going by JIS semiconductor numbering, 2SC marks an NPN bipolar transistor; the name gives no…

Named for the 2SC4003, this 79.4 KB PDF is listed as a schematic but appears to be a transistor datasheet.

Covering the 2SC3599, this 124 KB PDF is a discrete transistor datasheet even though it is filed as a schematic.

The 2SC5323 is the only clue in this file name, so treat this 122 KB PDF as a probable transistor datasheet even though it sits in the schematic category.

This 145 KB PDF carries only the part number 2SC2884 in its name and is filed as a schematic.

At 190 KB this PDF is larger than most entries here and is named for the 2SC982, an NPN transistor according to the JIS 2SC prefix; the TM suffix in the name is not…
