Samsung GT-I9300 Galaxy S III service manual, revision 1.0, 9.31 MB PDF. Manuals of this type generally cover specifications, disassembly, block diagrams, schematics…

PDF for the 74AC00, a quad 2-input NAND gate in the advanced CMOS family, 302 KB, catalogued as a schematic; the name drops the digit before input, but the part number…

PDF for the KIA324P, a KEC quad operational amplifier compatible with the widely used LM324, in a DIP package as the P suffix suggests.

Stored under a lowercase name, this 52.3 KB PDF covers the 2sd2318 transistor. In the Japanese JIS scheme the 2SD series contains NPN devices for low-frequency duty, so…

A compact 23.3 KB PDF for the 2SK2772, an N-channel FET according to the JIS 2SK naming convention, catalogued here as a schematic.

The 2SK2750 is covered by this 394 KB PDF, indexed as a schematic but most likely the component datasheet, since 2SK is the JIS prefix for N-channel FETs.

Compact 33.0 KB PDF on the 2SK1834 transistor. The 2SK prefix belongs to the Japanese JIS designation system and means an N-channel field-effect device, so the content…

The name 2SK1446LS marks this 32 KB PDF as covering an LS-suffixed version of the 2SK1446.

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.

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.

The largest of this group at 334 KB, this PDF is named only 2SC4117 and, while labelled a schematic, should be the datasheet for that NPN bipolar transistor under…

Small 30.5 KB PDF for the 2SC5808 part, an NPN bipolar transistor per the Japanese 2SC designation.

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.

Datasheet for the 2SB1612, delivered as a 39.6 KB PDF whose _E suffix probably marks the English-language edition.

PDF datasheet-style file for the 2SB1290 transistor, only 38.7 KB, so likely a brief sheet of a few pages. The name carries no other details such as package or maker.

A 54.3 KB PDF, named in lowercase, for the 2SA1862 PNP bipolar transistor of the JIS 2SA series.

Toshiba-style part number 1SV264 names this 65.3 KB PDF, which the index lists under schematics.

Family datasheet for the 1N5817, 1N5818 and 1N5819 Schottky rectifiers, 1 A devices rated 20, 30 and 40 V.

PDF datasheet for the 93C75A serial EEPROM, part of the 93-series three-wire Microwire memory family, filed under schematics with a size of 395 KB.

PDF of 97.3 KB listed as a schematic and named 28C512-513, covering two related parts from the 28C parallel EEPROM family in one document.

Weighing 332 KB, this PDF is titled 25C160, a name that resembles a serial memory part code, so treat it as a chip datasheet rather than a motherboard schematic.
