Named 2SD1934 with an _E suffix, this 40.2 KB PDF is most likely the datasheet for that NPN transistor, since 2SD is the JIS prefix for NPN low-frequency types.

The 42.4 KB PDF is named for the 2SD2345 and carries an _E suffix, whose meaning the name does not explain.

Second copy of documentation for the 2SK2887, a 139 KB PDF listed under schematics, with the part number written in lower case and no other information in the name.

PDF datasheet, 411 KB, for the 2SK2847, placed in the schematic category of the index. Only the part number is given in the name, with no maker or revision.

Catalogued as a schematic, this 86 KB PDF is named only after the part number 2SK2273, so it is almost certainly a component datasheet, not a board diagram.

Component documentation for the 2SK1475, a JIS-style part number whose 2SK prefix identifies an N-channel FET.

Compact 30.7 KB PDF covering the 2SJ628, catalogued as a schematic but most likely a single-device datasheet given the part-number name.

Identified solely as 2SJ257, this 96.0 KB PDF most likely documents a P-channel FET, the device class assigned the 2SJ prefix in the JIS system.

Datasheet-style PDF of 88.9 KB for the 2SC4361, listed in the schematic category although the file name holds nothing but the part number.

Datasheet-style document for the 2SC5405, stored as a 37.3 KB PDF in the schematic category. Nothing beyond the part number appears in the name.

The 2SC3153 is the subject of this 98.0 KB PDF, catalogued as a schematic though the name points to a discrete-part data sheet.

Part number 2SC2851 with an _E suffix names this 48.7 KB PDF, listed as a schematic. The 2SC prefix follows JIS numbering for NPN bipolar transistors, so a datasheet is…

Compact 57.8 KB PDF named after the 2SC2206, with an _E suffix in the file name whose meaning is not stated.

The 2SC1359 named in this 55.6 KB PDF is, by its 2SC prefix, a Japanese-standard NPN bipolar transistor, so despite the schematic label the document should be a…

Although catalogued as a schematic, this 51.4 KB PDF is named for the 2SC1317, which the JIS 2SC prefix identifies as an NPN bipolar transistor, so a component datasheet…

Component datasheet for the 2SB1434 transistor, filed under schematics but in practice a part reference rather than a board diagram.

A PDF document for the 2SA1604, an 84 KB file listed in the index as a schematic but named after a single discrete part rather than a board.

An 80.4 KB PDF covering the 2sb1260 transistor, listed in the index under schematics. No maker, package or device model is given in the name.

Datasheet PDF of 229 KB for the 2SA1162, a PNP bipolar transistor named under the Japanese JIS 2SA convention.

Part document for the 2SA1735 transistor, stored as a 151 KB PDF and catalogued under schematics.

PDF of 97.5 KB covering the 2SA1729, a component listed in this index as a schematic although the name describes a single part.

Component sheet for the 2SA1723, an 80.1 KB PDF. The name holds only the part number, so no equipment model or board revision can be attached to it.

Part reference for the 2SA1708, saved as a 154 KB PDF. No device, brand or board number is present in the name, only the component designation.

A PDF of about 155 KB for the JEDEC part number 2N6338, filed under schematics but almost certainly a component datasheet.

A short 87.3 KB PDF for the 1SS403. It sits in the schematic category but reads as a component datasheet, because 1SS is the Japanese designation family for small-signal…

The name 1ss244 indicates a datasheet for a small-signal diode in the Japanese JIS 1SS series, although the file sits in the schematic category.

Component datasheet for the 1N4936, filed under schematics and stored as a 45.5 KB PDF.

At 377 KB this is the largest of a group of PDFs named after 1N part codes; this one is 1N1183, a JEDEC style diode designation, so it is most probably a datasheet even…

Datasheet in PDF, about 91 KB, for the 93C66 serial EEPROM, the 4 Kbit member of the widely used 93-series Microwire family; the _3 suffix in the name likely marks a…

Listed as a schematic, this 553 KB PDF named 29040a is most probably a datasheet revision for a 4 Mbit 29-series parallel flash part, the a suffix suggesting a later…

The name of this 237 KB PDF is just the number 2416, and it is filed as a schematic without any brand, model or revision.

Code 52CPQ030 is the only information in the name of this 69.9 KB PDF, which is filed under schematics. No laptop model or board number is mentioned.

Catalogued as a schematic, this 77.1 KB PDF named 30SLJQ060 carries a discrete rectifier style part number, so treat it as a component datasheet.
