Combined datasheet for the BC546 and BC547 NPN small-signal transistors, packaged as a 57.5 KB PDF.

Named 3LN02C, this 41.8 KB PDF is filed among schematics but its name is a component-type code with a C suffix and gives no device or board details.

Another copy of documentation for the 2SD1458 NPN transistor, stored as a 48.8 KB PDF under a lowercase file name.

At 294 KB, this PDF is larger than its neighbours but still identified only by 2SJ167, a Japanese JIS number for a P-channel field-effect transistor.

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 U20 smartphone, about 2.26 MB in RAR format, with no further detail in the name about its contents.

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

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

A 129 KB PDF filed under schematics, though its name, 2SC3807, is simply a transistor type number.

The 2SC3552 transistor is documented in this 121 KB PDF, catalogued under schematics though it is a component datasheet.

Filed under schematics, this 49.7 KB PDF covers the 2SC1318A, an NPN transistor in JIS numbering; the A suffix denotes a variant of the base 2SC1318 type, often with…

English-edition datasheet, judging by the _E suffix, for the 2SB1599 PNP bipolar transistor, 43.5 KB in PDF.

Reference sheet for the 2SA1182 transistor, stored as a 202 KB PDF. The 2SA prefix belongs to the JIS numbering system and identifies a PNP bipolar device, so the…

Compact 23.8 KB PDF for the 2SA1870 PNP transistor, named in lowercase with only the part number.

PDF of 47.9 KB filed as a schematic and named for the part 2PA733, revision 4 by its suffix.

Small PDF reference, 47.7 KB, for the part 2PD601A, with the trailing 4 most likely the sheet revision.
