Small 197 KB PDF for the Gigabyte GA-Z170X-Gaming G1, revision 1.0, labelled as boardview despite the PDF format.

Schematic package for Samsung model A047F, which matches the Galaxy A04s numbering, in a 2.01 MB ZIP archive.

Component sheet for the 2SK2886 transistor, delivered as a 424 KB PDF and filed in the schematic category. The name carries only the part number.

Datasheet-style PDF for the 2SK669, a part number in the JIS 2SK series used for N-channel field-effect transistors, listed in the index as a schematic.

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.

Only the part number 2SJ512 appears in the name of this 455 KB PDF, which the index lists among schematics.

The 2SJ419 is covered by this 100 KB PDF, filed under schematics though the part number points to a discrete transistor datasheet.

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.

Samsung SM-A205F schematics, the Galaxy A20, provided as PDF files inside a RAR archive of about 4.06 MB.

For the 2SC4006 there is this 79.6 KB PDF, filed as a schematic though a bare JIS code like this normally names a datasheet.

Covering the 2SC3599, this 124 KB PDF is a discrete transistor datasheet even though it is filed as a schematic.

The 2SC3552 transistor is documented in this 121 KB PDF, catalogued under schematics though it is a component datasheet.

The 2SC5323 is the only clue in this file name, so treat this 122 KB PDF as a probable transistor datasheet even though it sits in the schematic category.

Small PDF reference, 47.7 KB, for the part 2PD601A, with the trailing 4 most likely the sheet revision.

Combined datasheet covering both the 2N2905A and 2N2907A PNP transistors in one 726 KB PDF, filed under schematics.

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.

Part number 1N1199A is the only information in the name of this 104 KB PDF, which is indexed as a schematic but follows the JEDEC 1N pattern used for diodes, pointing to…

The name 251UL80S is a manufacturer part code rather than a board number, so this 143 KB PDF is likely a power semiconductor datasheet even though it is listed as a…

Named 244NQ035, this 44.5 KB PDF is indexed under schematics but its title is a component part number from a family of power rectifiers, so treat it as a datasheet.

The name 243NQ gives only a part family prefix with no suffix, so this 45.4 KB PDF probably covers a whole series of power rectifier devices in one datasheet, despite…

This small PDF of 164 KB lists the 6A05G to 6A10G range, a naming style typical of general-purpose 6 A axial rectifier diode families, so it is almost certainly a…

Listed as a schematic but carrying the part code 162cmq030, this 46.3 KB PDF is most likely the datasheet for a common-cathode dual Schottky rectifier rated around 30 V.

The name of this 72.9 KB PDF holds just the code 130MT080KB, catalogued as a schematic with no board number, revision or brand.

Catalogued as a schematic, the 1SR35-400A document is a 92.2 KB PDF with a discrete component style name and the 400A suffix denoting one grade.

A small 56 KB PDF filed under schematics, named only 40CPQ080. The name looks like a component part code, not a motherboard number, and it states no device, brand or…

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.

Named 30CPQ150 and saved as a 128 KB PDF, this item appears to be a component datasheet, since the title follows a discrete semiconductor numbering pattern rather than a…

PDF of 55.5 KB titled 30CPQ035, a code following discrete semiconductor numbering, so it is best treated as a datasheet despite the schematic label.

A 447 KB PDF datasheet for the 24AA256, 24LC256 and 24FC256 I2C serial EEPROMs, each storing 256 Kbit.
