Part document for the 2SC4517, a 27.9 KB PDF listed as a schematic; the name holds only the part number.

PDF reference on the 2SC4517 transistor, the name noting it as NPN; the file is 26.9 KB and indexed as a schematic.

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

The 3N258 is the subject of this 42.2 KB PDF, indexed as a schematic but in practice a component reference.

Another copy of documentation for the 2SD1458 NPN transistor, stored as a 48.8 KB PDF under a lowercase file name.

The smallest sheet of its group at 24.4 KB, this PDF concerns the 2sk2573, an N-channel field-effect transistor by the JIS 2SK prefix.

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.

At just 31.4 KB, the PDF named 2SJ499 is probably a short datasheet or summary sheet, even though it is filed as a schematic.

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

Samsung SM-A127F repair archive in RAR format, about 2.29 MB, named only by the model code with no hint of its exact contents.

Compressed RAR archive, 5.12 MB, for the OPPO R11s smartphone. The name gives no more than the model, so contents such as schematics or a board layout have to be checked…

Copy-numbered RAR archive for the OPPO R7s, 1.29 MB, matching the size of the other R7s package and therefore probably a duplicate.

ZIP archive of 1.46 MB for the original Apple iPhone, commonly called the iPhone 2G. The name states only the model, so the precise contents should be checked after…

Repair archive for the Apple iPad 3, delivered as a 1.66 MB ZIP file. The name mentions only the model, so open it to see whether it carries a schematic, a boardview or…

Archive named G973F, the model code of the Samsung Galaxy S10 international variant, packed as a 7.70 MB RAR.

Named only 2SC4161, this 98.6 KB PDF is categorised as a schematic yet, judging by the part number, documents an NPN bipolar transistor under the JIS designation scheme.

The largest of this group at 334 KB, this PDF is named only 2SC4117 and, while labelled a schematic, should be the datasheet for that NPN bipolar transistor under…

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.

A 129 KB PDF filed under schematics, though its name, 2SC3807, is simply a transistor type number.

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

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

Compact 128 KB PDF bearing the part number 2SC2983, indexed as a schematic. Under the Japanese JIS naming convention a 2SC number denotes an NPN bipolar transistor, so…

At 190 KB this PDF is larger than most entries here and is named for the 2SC982, an NPN transistor according to the JIS 2SC prefix; the TM suffix in the name is not…

The 2SB1642 PNP transistor is documented in this 181 KB PDF, listed as a schematic though it is a part 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.

Data sheet sized PDF of 45.9 KB named 2PC4617J, revision 2 judging by the suffix. The J suffix normally separates a package or variant from the base 2PC4617 part, which…

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.

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

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

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.

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.

Series datasheet in PDF form, roughly 109 KB, titled 8GBU series and indexed as a schematic.

Compact 32.6 KB PDF for the 6N138 and 6N139, filed as a schematic. These numbers are a well-known family of high-gain optocouplers, so the file is almost certainly a…
