Named for the 2SD1618 transistor, a 116 KB PDF listed as a schematic but most plausibly the part's datasheet.

A 41.5 KB PDF covering the 2SC4808, a part number in the JIS 2SC series used for NPN bipolar transistors.

The 2SC5684 part number heads this 126 KB PDF, which should be a component datasheet: 2SC is the Japanese JIS code for NPN bipolar transistors.

A 69.5 KB PDF for the 3SK248, catalogued as a schematic and most likely a manufacturer datasheet for the part. Only the type number is stated.

Covering the 2SA1422 transistor, this PDF weighs 91.8 KB, close to the 2SA1423 file, which suggests a similar document format.

Framework diagram showing the CPU I2C bus layout for iPhone models from the iPhone 6 through the 11 Pro Max, packaged as a small RAR archive.

Physical scanning diagram for the iPhone 11 Pro and 11 Pro Max, supplied as a RAR archive just under 1 MB.

Named only 2SC4161, this 98.6 KB PDF is categorised as a schematic yet, judging by the part number, documents an NPN bipolar transistor under the JIS designation scheme.

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

Another reference for the IRF540 power MOSFET, provided as a 117 KB PDF and indexed as a schematic despite being named a datasheet.

Datasheet-type PDF of about 90.7 KB for the 2SC4413. No board, brand or revision appears in the name; the JIS 2SC prefix simply indicates an NPN bipolar transistor.

At 108 KB, this PDF is labelled with the transistor type 2SC4221 and nothing else, so no board, model or revision is identified.

Datasheet PDF of 286 KB covering the 24AA515, 24LC515 and 24FC515, Microchip serial EEPROMs of 512 Kbit (64 KB) on the I2C bus.

Version of the 2N5401 high-voltage PNP transistor datasheet tagged Sam in the name, a 53.3 KB PDF.

PDF schematic for an unidentified Xiaomi device, 965 KB, whose name only marks it as a full set without the model or PCB revision.

Xiaomi schematic in PDF format, 166 KB, whose file name only says full and gives no model or board number.
