Circuit diagram for the Z94 board, revision 1.1, as a 902 KB PDF. No brand or full board number appears in the name, so the cover page should be consulted to confirm the…

Schematics for the Sony PCG-FR310 notebook, built on the MBX-80 mainboard that Quanta designed under the NE5 project code.

Asus X550DP repair guide as a 508 KB PDF. The file name names only the model, without a motherboard revision.

Repair guide for the Asus X450JN notebook in a 1.01 MB PDF. The motherboard revision is not stated in the name, so confirm it from the document.

PDF covering the BUW84 and BUW85 transistors in a single 101 KB document, filed as a schematic.

Datasheet-style PDF covering the BD233, BD235 and BD237 family of medium-power transistors, filed here under schematics.

Named 3LN02C, this 41.8 KB PDF is filed among schematics but its name is a component-type code with a C suffix and gives no device or board details.

A fairly detailed 200 KB PDF for the 2SD2352, a JIS-numbered NPN transistor, where the 2SD prefix denotes NPN low-frequency parts.

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…

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.

Filed under schematics, this 98 KB PDF is named after the part number 2SC4671, which follows the Japanese JIS designation for an NPN bipolar transistor.

Datasheet in PDF form for the 2SC4696, filed in the index under schematics although the name points to a discrete part document rather than a board diagram.

Small PDF of 25.0 KB dedicated to the 2SC4064, catalogued as a schematic. Going by JIS semiconductor numbering, 2SC marks an NPN bipolar transistor; the name gives no…

The 2SC3606 is the only detail given by this 464 KB PDF, catalogued as a schematic yet functionally a part datasheet.

Component data for the 2SB1527 in PDF form, roughly 73 KB, catalogued as a schematic though the bare part number suggests a datasheet.

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.

Compact 23.8 KB PDF for the 2SA1870 PNP transistor, named in lowercase with only the part number.

PDF of 47.9 KB filed as a schematic and named for the part 2PA733, revision 4 by its suffix.

The 2N4126 is the subject of this 81.9 KB PDF, listed in the schematic section of the catalogue but almost certainly a single-part datasheet.

File for the 2N3904 with a _3 suffix, 51.2 KB PDF; the suffix probably distinguishes it from another copy or edition, but the name does not state its meaning.

Short PDF of only 19.4 KB covering the 1SV298H, the H suffix marking a variant of the base 1SV298 part.

Part 1SS352 is the only information in this 68.4-style short PDF name; the file is 69.2 KB and most likely the data sheet for that small-signal silicon diode, as…

A 52.8 KB PDF labelled 1SS351, catalogued as a schematic though the name is just a component number.

PDF datasheet of 64.7 KB covering Zener diodes from 1N4728A to 1N4754A, a subset of the 1 W axial Zener series.

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.

Listed as a schematic, this compact 47.4 KB PDF is named 80CLQ150, a code that resembles a power semiconductor part number rather than a board number.

The 163 KB PDF named 408CNQ060 sits in the schematic category, yet its name identifies no device or board.

Catalogued as a schematic, this 61.8 KB PDF is identified only by the code 70u, with no laptop model, board number or revision stated.

Indexed as a schematic, the 75.3 KB PDF titled 30TPS appears to be a family datasheet for a series of power semiconductors sharing that prefix, rather than a circuit…

PDF document of 202 KB named 25CTQ, a series-style code with no voltage suffix, so it probably covers a family of related components in datasheet form.

Covering the 24WC33 and 24WC65, this 56.1 KB PDF is listed as a schematic but is a Catalyst Semiconductor datasheet for 32 Kbit and 64 Kbit I2C serial EEPROMs.
