Schematic package for a device identified only as J100H, supplied as a 1.8 MB RAR archive.

Samsung R590 BIOS dump labelled JS01SA, presumably a regional or configuration code, and tagged ok as a working image.

Reference sheet for the 2SK2739 in PDF format, 146 KB, indexed in the schematic section.

The 2SK1429 is covered by this compact 99.1 KB PDF, entered in the schematic category although a lone part number usually signals a datasheet.

Datasheet PDF for the 2SD1222, sized 183 KB and placed in the schematic section of the index.

Datasheet-type PDF of 220 KB for the 2SC5260, carried in the schematic section of the index.

Filed in the schematic section, this 156 KB PDF is named for the 2SC4135, which by JIS convention is an NPN bipolar transistor, so expect a component datasheet inside.

A 126 KB PDF for the 2SC4871, given with only the part number and filed in the schematic section.

A 147 KB PDF whose name is just 2SC2881, catalogued as a schematic. By JIS numbering this is an NPN bipolar transistor, and the file is most likely its datasheet rather…

The 2SA1420 is the subject of this 91.5 KB PDF, which sits in the schematic section but by its naming is a part-level datasheet.

This 26.1 KB PDF, placed in the schematic section, is named after the 2N6517, part of the JEDEC 2N numbering used for discrete transistors and similar devices.

Catalogued among schematics, this 213 KB PDF carries the part number 2N6426 and an RE suffix whose meaning the name does not give.

At 82.2 KB, the 1SV228 PDF is the largest of this group and is indexed as a schematic. The underscore after the code seems to be just part of the file naming.

Short PDF datasheet, 42.1 KB, for the 1N6098 diode, indexed in the schematic section though it covers one discrete component.

Component datasheet for the 1N5401, the 100 V grade of the 3 A 1N5400 rectifier series, provided as a 43.4 KB PDF in the schematic section.

Glass passivated 1N4935GP fast recovery rectifier datasheet, a 45.7 KB PDF in the schematic section.

PDF datasheet covering the 1N4148 and 1N4448 fast switching diodes, filed in the schematic section of the index.

Catalogued as a schematic, this 432 KB PDF named 29040l most likely documents a 4 Mbit 29-series parallel flash memory, the l suffix probably marking a low-voltage or…

Only the number 29010 names this 727 KB PDF, listed as a schematic; the pattern most likely corresponds to a datasheet for a 1 Mbit 29-series parallel flash memory, with…

A 163 KB PDF filed as a schematic and named 28F010 followed by an underscore, likely a second edition or vendor version of the same device sheet.

Alternative 135 KB PDF for the 25C02 code, its name differing from the other 25C02 sheet only by a trailing underscore.

PDF of 177 KB titled 29F010, filed in the schematics section with no brand or board named.

Schematic PDF for a board identified as UL50AT, 1.23 MB in size. The name gives no revision or brand, so check the title block inside the document for the board version.
