Laptop motherboard schematic for the Quanta R23 project, about 900 KB in PDF format. The name does not reveal the laptop brand, model or board revision, so open the…

Windows executable named Winflash, a utility for updating BIOS firmware from within Windows.

Datasheet-style PDF named for the 3N257, roughly 42 KB and listed in the schematic category.

The JIS-style code 2SD2416 plus an E tag names this 56.1 KB PDF, which sits among schematics but most likely covers one NPN bipolar transistor, as the 2SD prefix…

At 422 KB, this is the largest file in the set, a PDF for the 2SK3296 transistor indexed as a schematic.

Documentation for the 2SK2700, a part named under the Japanese JIS system where 2SK denotes an N-channel FET.

The 2SK2605 is the subject of this 411 KB PDF, filed as a schematic although its name is purely a semiconductor part number.

A 35.0 KB PDF referencing the 2sk2574, listed with schematics but named solely by its part number.

PDF of 111 KB describing the 2SK2467, catalogued as a schematic but named for a discrete transistor.

The 2SK2294 is the subject of this 140 KB PDF, catalogued as a schematic but in substance most likely a datasheet, as 2SK marks N-channel field-effect transistors under…

The 2SK1736 is documented in this 92.6 KB PDF. Under JIS designations, 2SK means an N-channel FET, so the file is almost certainly a component datasheet despite its…

Here is the 389 KB PDF for the 2SK1359 MOSFET, part of the Japanese 2SK family of N-channel field-effect transistors.

Filed as a schematic, this 372 KB PDF named 2SJ465 most likely holds the full datasheet for a P-channel field-effect transistor, since that is what the 2SJ prefix means…

The 2SJ316 is the subject of this 91.5 KB PDF. Its name gives only the semiconductor type code, so no equipment model can be inferred.

Short PDF of roughly 41.2 KB for the 2SJ289. Nothing in the name besides the part number points to a specific device.

Labelled only 2SJ254, this 93.0 KB PDF is filed as a schematic but almost certainly describes one discrete component: the 2SJ prefix in the JIS system denotes a…

Datasheet-type file for the 2SD1237L, a 143 KB PDF listed under schematics. Per JIS numbering, 2SD identifies an NPN bipolar transistor for low-frequency work; the L…

Compact 53 KB PDF for the 2SC4606, carrying an _E suffix that may mean an English edition, though the name does not say so explicitly.

Part-number document for the 2SC5173, stored as a 231 KB PDF under the schematic category.

A 93.3 KB PDF data sheet for the 2SC4520, a JIS-coded part where the 2SC prefix means NPN bipolar transistor.

Datasheet-style PDF named for the 2SC4430, sized 108 KB and listed as a schematic in the index.

Component documentation for the 2SC4425 in a 102 KB PDF. The JIS prefix 2SC denotes an NPN bipolar transistor, which points to datasheet content rather than a device…

PDF file of roughly 104 KB identified only by the part number 2SC4424. Under the Japanese JIS numbering scheme, 2SC parts are NPN bipolar transistors, so the document…
