Datasheet-style PDF, 142 KB, for the 74HC595D, the familiar 8-bit serial-in, parallel-out shift register with output latches; the D suffix usually marks the SO package.

PDF for the complementary TIP3055 NPN and TIP2955 PNP power transistors, 50.1 KB, indexed under schematics.

Datasheet for a part marked D304X, provided as a 924 KB PDF. The file name gives no description of the component category or manufacturer, so the document itself must be…

Small 67.8 KB PDF for the 2SD1854, a part number in the Japanese 2SD series of NPN bipolar transistors, so it is really a datasheet rather than a full schematic.

Datasheet for the 2SD2258 NPN bipolar transistor, supplied as a 56.8 KB PDF and filed under schematics.

A compact 44.3 KB PDF describing the 2SD602 transistor, indexed as a schematic though its content is component data. An _E suffix appears in the name as an edition tag.

A 29.2 KB PDF documenting the 2SD2639 part, catalogued as a schematic. Nothing beyond the type number is stated in the name.

Component reference for the 2SD2635, a 35.2 KB PDF listed among schematics. The file name offers only the part number, with no manufacturer or revision given.

Covering the 2SD1817, this 75.8 KB PDF is indexed as a schematic but by name is a component datasheet. No maker or revision is indicated.

The 2SD2598 transistor is covered in this 59.3 KB PDF, whose name ends in an _E suffix.

Part datasheet for 5HP01SP, a 27.5 KB PDF. The name carries no model, brand or board number, only the device code with an SP suffix that likely identifies its package.

A 41 KB PDF covering the part coded 5HN02SP, listed with schematics but naming only a component. SP is most likely the package designation in the 5HN02 series.

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.

A compact 49.9 KB PDF for the 2SD2074, with an _E suffix in the name that is not explained and could indicate a language edition or document revision.

Small 56.9 KB PDF for the 2SD1679, with an extra E suffix in the name that is not explained further.

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

Datasheet-style PDF for the 2SD1423, 41.0 KB, stored as a schematic; the trailing _E in the name is not explained by the file itself.

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.

Reference sheet for the 3SK143, delivered as a 35.1 KB PDF and indexed under schematics. Beyond the part number the name says nothing.

A 32.8 KB PDF for the 3SK273, indexed as a schematic though it is likely a manufacturer datasheet.

Reference PDF for the 3N255, sized at 42.2 KB and catalogued among schematics, though nothing beyond the part number is given in the name.

Datasheet-style PDF for the 3LP02N, about 41.5 KB and listed as a schematic. No device, brand or board details appear in the name beyond the part code itself.

Reference sheet of 41.7 KB in PDF format for the 3LP02M, filed among schematics though it is effectively a component datasheet.

Catalogued as a schematic, the PDF 3LN01SP (27.5 KB) is named only after a part-style code with an SP suffix, with no device model, board number or revision stated.

Datasheet-style PDF for the 2SD1994A transistor, filed in the schematic category of the index.

File name 2sk198 is a JIS semiconductor number, so this 31.8 KB PDF, though catalogued as a schematic, is best treated as a brief component datasheet.

The 34.0 KB PDF named 2SK3557 is indexed as a schematic, but its name is a JIS component number, so it is almost certainly a datasheet.

A 318 KB PDF covering the 2SK2882, listed under schematics but almost certainly a datasheet given the bare part number in its name.

Covering the 2SK2865, this 424 KB PDF sits in the schematic category but, judging by its name, is the component datasheet.

Listed as a schematic, this 412 KB PDF carries only the part number 2SK2845 in its name.

The 2SK2792 part number appears here with an unexplained 1-5 suffix, possibly a page range or edition marker.

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.

Covering the 2sk2580, this 34.5 KB PDF is labelled a schematic yet identifies only a semiconductor part, pointing to a short datasheet.
