HP archive labelled DVB 11A40-2 together with 48.4RI03.021, a number in the format Wistron uses for its board part numbers.

Reference PDF for the HCF4050B, a non-inverting hex buffer from the CMOS 4000 family, as the file name itself states.

PDF document of 577 KB for the AD620, filed in the schematic category although a part-number name like this normally indicates a component datasheet.

PDF reference, 218 KB, for the LA7286, an IC from the LA series, a prefix associated with Sanyo linear integrated circuits.

Part datasheet in PDF for the MJE13007F, a high-voltage NPN switching transistor. The F suffix usually denotes an isolated fully plastic package, though the name states…

Datasheet PDF for the BD234, only 49.2 KB and indexed as a schematic. The BD234 is a medium-power PNP transistor in a plastic package, commonly paired with a…

Manufacturer datasheet for the BD139 transistor, with the name indicating the ST (STMicroelectronics) version, supplied as a 152 KB PDF.

Compact 29.7 KB PDF for the 2SD2649, placed in the schematic section though the name indicates a component datasheet.

Reference PDF of 40.9 KB for the 2SD1819A, with an E tag in the name that probably denotes an English-language edition, filed under schematics.

A 28.0 KB PDF classed as a schematic whose name, 3LP01C, reads as a component part code ending in C. The file name gives no device, board number or manufacturer.

PDF of 41.6 KB, catalogued as a schematic and named 3LN02M, which looks like a semiconductor part number with an M suffix rather than a board code.

The smallest of this group at 26.5 KB, this PDF carries the code 3LN01SS, resembling a discrete semiconductor part number with an SS suffix, and is catalogued as a…

Although filed as a schematic, this 37.9 KB PDF is named after 2SD2460 with an extra E tag the name does not explain.

The 2SD1908 transistor is documented in this 85.8 KB PDF, which the index files as a schematic, although a JIS part number like this normally indicates a datasheet.

Named only 2sd1897, this 35.6 KB PDF is listed as a schematic, yet the name is a JIS transistor number, so it is very likely a compact datasheet.

A 30.6 KB PDF labelled with the JIS part number 2SK3488 and filed in the schematic category, though the content should be a component datasheet.

The 2SK2884 is the subject of this 428 KB PDF, indexed as a schematic though it is most likely the manufacturer datasheet for the part.

Brief 28.4 KB PDF for the 2SK2864, indexed as a schematic; its small size points to a one or two page datasheet or summary. The name gives only the part number.

PDF of 137 KB for the 2SK2793, with a 1-5 suffix in the name whose meaning is not explained; it may indicate a page range or document version.

PDF of 140 KB for the 2SK2739 with an unexplained 1-5 suffix, which may indicate an edition or page count rather than a different part.

Compact 23.1 KB PDF named only with the part number 2SK2277. Because 2SK is the JIS prefix for N-channel FETs, the schematic category here most likely holds a short…

PDF reference, 35.6 KB, for the 2SK2276, a Japanese JIS-registered device where the 2SK prefix indicates an N-channel field-effect transistor.

Short 23.7 KB PDF for the 2SK2014, a part number from the JIS 2SK series used for N-channel FETs.

Small 33.2 KB PDF covering the 2SK1478, written in lowercase in the original name. The 2SK prefix belongs to the Japanese semiconductor designation for N-channel…

The 2SK445 part number is all the name provides for this 89.6 KB PDF, filed as a schematic but best treated as a datasheet, as 2SK numbers designate N-channel…

The file name gives nothing beyond 2SJ562, a JIS-style designation; the 2SJ prefix denotes a P-channel field-effect transistor.

This 170 KB PDF carries the part number 2SJ502 and is indexed under schematics. In JIS naming, 2SJ marks a P-channel FET, so the document is expected to be the datasheet…

A 105 KB PDF for the 2SJ421, catalogued as a schematic but in practice a component datasheet, since the 2SJ prefix in the Japanese JIS numbering system marks a P-channel…

Reference sheet for the 2SJ418 P-channel FET, supplied as a 128 KB PDF and indexed as a schematic.

Only the transistor number 2SJ259 appears in the name of this 99.0 KB PDF. JIS coding uses 2SJ for P-channel FETs, which suggests a datasheet even though the file is…

Filed as a schematic, this 86.2 KB PDF is named after the 2SJ229, a Japanese JIS-registered part number where the 2SJ prefix denotes a P-channel field-effect transistor…

The 2SJ225 is the only information this 91.8 KB PDF name provides; the 2SJ prefix in Japanese semiconductor numbering identifies a P-channel field-effect transistor.

Listed as a schematic, this 246 KB PDF carries the name 2SJ201, a JIS part number for a P-channel FET, so it is best treated as a component datasheet.

Datasheet-style PDF covering the 2SD1199, catalogued under schematics, with an _E suffix in the name that the file does not explain.

Datasheet for the 2SD875 NPN transistor, supplied as a 43 KB PDF; the _E suffix in the name most likely marks an English-language edition, though this is not certain.

Compressed RAR package for the Samsung SM-A125F, 1.80 MB, whose name gives the model code and nothing more about what is inside.

RAR archive of 5.61 MB for the OPPO R15 smartphone. Only the model appears in the name, so the contents, whether schematics, board layouts or both, need to be checked…
