Filed as a schematic, this 53 KB PDF is named after the 2SD1725 part number, so it is most likely a component datasheet rather than a board diagram.

Labelled 2SD1997, this 86.1 KB PDF is indexed as a schematic, yet a bare transistor part number points to a manufacturer datasheet.

Datasheet-type PDF for the 2SD1878, 90.6 KB, placed in the schematic category of the index. The name contains nothing beyond the part number.

Datasheet PDF, 43.0 KB, for the 2SD2321, with an _E suffix carried over from the original name, though the suffix itself is not explained.

Here the 2SK2746 is documented in a 420 KB PDF, categorised as a schematic yet named like a single-part datasheet.

Compact 30.7 KB PDF for the 2SK2593, filed as a schematic though the lowercase name is simply a semiconductor part number.

Short PDF of 23.2 KB named for the 2SK2324 part. In JIS nomenclature 2SK denotes an N-channel FET, so this schematic-labelled file is presumably a brief datasheet.

A PDF of about 88 KB for the 2SK2154, filed under schematics but most likely a component datasheet, since the name is just the part number.

The 2SK2010 transistor is documented in this 90.1 KB PDF, filed among schematics but in substance a datasheet for an N-channel FET, as the JIS 2SK prefix indicates.

Part-number PDF for the 2SK1471, 92.5 KB in size and labelled as a schematic in the index.

Datasheet-style PDF for the 2SK1117, with the name noting NTE2379 as its equivalent, meaning the NTE replacement line lists that part as a cross-reference.

Component sheet for the 2SK1069, an N-channel FET from the Japanese 2SK numbering range, stored as a 98.7 KB PDF.

Short 37.3 KB PDF for the 2SK544, a part number belonging to the JIS 2SK series of N-channel FETs; although indexed as a schematic, it should be a component datasheet.

A PDF filed under schematics but named after the 2SK404, a part number in the Japanese JIS semiconductor scheme, where the 2SK prefix marks an N-channel field-effect…

Datasheet-style PDF of 105 pages' worth of nothing more than a part number: the 2SJ420, a device whose 2SJ prefix under Japanese JIS designation identifies a P-channel…

The 2SD1198 is the subject of this 56.6 KB PDF, filed as a schematic although the name points to a component datasheet; an _E suffix follows the part number with no…

Named after the transistor type 2SC4646, this 148 KB PDF most likely contains the part datasheet. No board, model or revision is mentioned.

A 39.6 KB PDF for the 2SC5216, with an _E tag in the name that is not explained. It is listed as a schematic, but the name points to a transistor datasheet.

Bearing only the part number 2SC4393, this 319 KB PDF is indexed as a schematic yet is most likely the transistor datasheet.

Reference document for the 2SC5089 NPN transistor, supplied as a 465 KB PDF and filed with schematics.

Compact 43.3 KB PDF covering the 2SC5551, a JIS-coded NPN bipolar transistor, even though the catalogue type says schematic.

Catalogued as a schematic, this 100 KB PDF is named after the 2SC4031 and is most likely its datasheet. JIS numbering uses 2SC for NPN bipolar transistors.

Single-part reference for the 2SC4864 in a 118 KB PDF, catalogued as a schematic. Apart from the part number, the name gives no information.

Part number 2SC3401 is the only information in the name of this 87.3 KB PDF, so no device or board is identified.

A 508 KB PDF filed under schematics, named only with the JIS part number 2SC2996. The 2SC prefix identifies an NPN bipolar transistor, so the document is probably a…

A 29.2 KB PDF carrying the part number 2SB1683, a PNP transistor by Japanese JIS naming; though labelled as a schematic, it is expected to be the component datasheet.

An 89.5 KB PDF for the 2SA1590 transistor, listed under schematics but almost certainly a part datasheet given the name.

Named after the 2SA1537 transistor, this 41.0 KB PDF sits in the schematic category but should contain the manufacturer data for that part.

This 52.0 KB PDF covers the 2SB1218A, the A suffix being part of the stated part number, with a further _E tag in the name; despite the schematic category it is likely a…

An 85.0 KB PDF covering the 2SA1965, whose 2SA prefix under JIS rules marks a PNP bipolar transistor.

Datasheet-style PDF, 206 KB, for the 2SA1893 PNP transistor from the JIS 2SA family. Nothing in the name points to a specific device or board, so treat it as part…

A 113 KB PDF for the 2SA1887, a PNP bipolar transistor in the JIS 2SA numbering series.

A 150 KB PDF indexed as a schematic, named only after the JEDEC part number 2N6806. The name gives no device, board or package detail.

PDF reference sheet, 214 KB, for the 2N6282 discrete device, listed as a schematic but most likely a datasheet.

A 90.8 KB PDF titled only with the part number 2N5550, so no board, laptop model or revision can be matched.

Larger 546 KB PDF datasheet covering the 2N5400, a high-voltage PNP small-signal transistor; the size suggests a scanned or multi-part document.

Component datasheet for the 2N5366, a 60.8 KB PDF filed in the schematic category. The name gives only the part number, with no manufacturer, package or revision…

A compact 32.6 KB PDF for the 2N3773, a JEDEC-registered 2N-series transistor; despite the schematic label it is a component datasheet rather than a circuit drawing.

Data document for the 1SV302 diode, stored as a 72.1 KB PDF and catalogued as a schematic.

Labelled 1n6762, this 17.2 KB PDF appears to be a datasheet page for a JEDEC 1N-numbered device rather than a circuit diagram.
