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.

Indexed as a schematic, the 44.5 KB PDF named 2SD1328_E should be a datasheet for the 2SD1328, which the JIS 2SD prefix identifies as an NPN bipolar transistor for…

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

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.

Datasheet-sized PDF of 38.0 KB for the 2SC5474, with an _E suffix in the name that likely marks an English edition; that reading is an inference.

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

At 192 KB this PDF is somewhat larger than its neighbours and covers the 2SC3142 transistor, an NPN bipolar part under JIS 2SC numbering.
