Datasheet for the Fintek F71868A Super I/O controller, a 5.57 MB PDF. Super I/O chips on desktop motherboards handle functions such as hardware monitoring, fan control…

Maxim MAX1540 datasheet, an 838 KB PDF identified only by its part number. Read the opening page for the device function and electrical limits.

Datasheet document covering the PIC18F6580 and the related PIC18F6680 microcontrollers from Microchip, in PDF format.

A 3.50 MB PDF datasheet from Microchip describing the PIC16C717, PIC16C770 and PIC16C771 microcontrollers in one shared document.

Complete 3.65 MB datasheet for the mega640, 1281, 1280, 2561 and 2560, consistent with the Atmel AVR ATmega640/1280/1281/2560/2561 family, the larger AVR parts in 64 and…

Flash dump for Quanta board DAOYOFMBAJ1 revision J, taken from chip location U23, with the Management Engine region cleaned.

PDF of 41.6 KB, catalogued as a schematic and named 3LN02M, which looks like a semiconductor part number with an M suffix rather than a board code.

A 68.3 KB PDF bearing the name 2SD2324, a Japanese JIS designation for an NPN transistor, since 2SD marks NPN low-frequency devices.

A 116 KB PDF for the 2SK2731 bearing a 1-5 suffix that the name does not explain, perhaps an edition marker.

Reference sheet for the 2SJ418 P-channel FET, supplied as a 128 KB PDF and indexed as a schematic.

The 90.8 KB PDF is named only 2SJ273, a part number in the JIS series used for P-channel FETs.

Only the transistor number 2SJ259 appears in the name of this 99.0 KB PDF. JIS coding uses 2SJ for P-channel FETs, which suggests a datasheet even though the file is…

Datasheet for the 2SD875 NPN transistor, supplied as a 43 KB PDF; the _E suffix in the name most likely marks an English-language edition, though this is not certain.

Small RAR archive of around 512 KB labelled for the Huawei P9 smartphone. The name gives no detail about what is inside, so extract it and check whether it is a…

The name of this 176 KB PDF consists only of 2SC3790, a JIS-style part number in which 2SC denotes an NPN transistor.

Reference sheet for the 2SC5363 transistor, delivered as a compact 40.7 KB PDF and listed among schematics.

Named after the 2SC1383, this 51.4 KB PDF is listed as a schematic, yet the JIS prefix 2SC denotes an NPN bipolar transistor, so expect a part datasheet.

A 58.1 KB PDF labelled as a schematic and named after the 2SC1215, an NPN transistor by Japanese JIS naming, so it should be the datasheet for that discrete part.

Small 81.5 KB PDF named after the 2SA1724 part number and filed under schematics. Nothing else in the name identifies a product or circuit board.

Filed as a schematic, this 271 KB PDF is named after the discrete part number 2N5684 with an unexplained RE suffix, which may indicate a reissued edition.

A 272 KB PDF for part number 2N5555, with a rev0x tag in the name that seems to mark a document revision, though its exact meaning is not stated.

The file is a 56.2 KB PDF listed under schematics and labelled 1T408, with nothing else in the name to tie it to a specific product or board.

Part number 1SS345 is the only information in this 58.3 KB PDF name, so no laptop, board or revision is identified.

Labelled 1SS268, this 126 KB PDF appears to be a datasheet for a single component even though the index lists it as a schematic.

Part number 1SS196 gives this 68.1 KB PDF its name, which marks it as a datasheet for a single semiconductor rather than a full circuit diagram.

PDF datasheet, 45.5 KB, for the 1N4934 fast recovery rectifier diode from the 1N4933 to 1N4937 family.
