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

PDF document of 299 KB named for the 2SK117, most likely a datasheet even though the catalogue lists it as a schematic.

The file, a 28.4 KB PDF, is named 2SK3485 and catalogued as a schematic; the name is a JIS semiconductor number, so treat it as a short datasheet.

The 2sk2790 name on this tiny 21.3 KB PDF is the only information provided. Filed as a schematic, it most probably holds a brief datasheet for an N-channel field-effect…

Datasheet in a 33.2 KB PDF for the 2SK1967, a Japanese-registered N-channel field-effect transistor indicated by the 2SK prefix.

Datasheet PDF, 292 KB, for the 2SK1829 transistor. Under JIS naming, 2SK marks an N-channel FET; the file name gives only the part number, with no maker or package…

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.

Catalogued among schematics, the 43.5 KB PDF called 2SJ499's neighbour 2SJ485 refers to a semiconductor part; under the JIS scheme the 2SJ prefix designates a P-channel…

Here is a 42.3 KB PDF for the 2SC5264LS, indexed as a schematic. JIS numbering makes the 2SC prefix an NPN bipolar transistor, and the LS letters identify a variant of…

Base-version document for the 2SC4738, a 236 KB PDF placed in the schematic category. Following the JIS scheme, the 2SC prefix denotes an NPN bipolar transistor; F and…

Datasheet-style PDF of 88.2 KB for the semiconductor 2SC4475, catalogued in the schematic section.

The 2SC5144 is the only detail this 206 KB PDF name carries; despite the schematic label it is presumably the device datasheet for that transistor.

Named only after the part 2SC4363, this 88 KB PDF is catalogued as a schematic but is most likely the manufacturer datasheet for that transistor.

The 2SC5774 part number is all this 29.9 KB PDF name reveals, and the catalogue lists it as a schematic.

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

Filed under schematics, the 2SC3993 PDF (107 KB) is far more likely a component datasheet, since the name is simply a JIS transistor part number.

Reference PDF for the 2SC5420 transistor, 69.2 KB, indexed as a schematic though the bare part number points to a component datasheet.

A small PDF filed as a schematic, though the name is simply the part number 2SC3468, which follows the Japanese JIS semiconductor scheme where the 2SC prefix marks an…

Covering the 2SC5353, this 208 KB PDF sits in the schematic category but, judging by the name, documents a single transistor.

Component reference for the 2SC3124, a 294 KB PDF indexed as a schematic. The JIS 2SC designation identifies it as an NPN bipolar transistor, normally marked C3124.

Reference document for the 2SC3112 transistor, supplied as a 257 KB PDF and filed under schematics. The name holds only the part number.

Datasheet-style PDF of 170 KB for the 2SC1627A, the A-suffixed variant of a JIS-numbered NPN bipolar transistor, indexed as a schematic.

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.

Reference document for the 2SB1398 transistor, with an _E suffix in the name that is not explained and may indicate an edition or language version.

At 249 KB this PDF is the largest in the group and covers the 2SA1618, indexed as a schematic but in practice a transistor reference.

Indexed as a schematic, this 40.2 KB PDF is named 2SB1220 with an _E suffix and almost certainly contains the datasheet for that JIS transistor.

Small 21.4 KB PDF for the 2SA733 PNP transistor, with the UTC tag in the name pointing to the Unisonic Technologies version of this widely used general-purpose part.

The 2SA1315 PNP transistor, per the Japanese JIS 2SA prefix, is the subject of this 220 KB PDF.

The 2SA1298 is covered by this 203 KB PDF, catalogued as a schematic but named only after the component.

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…

Datasheet PDF of 42.2 KB for the 2SA1883, identified only by its part number. Japanese JIS numbering uses 2SA for PNP bipolar transistors, so the content describes a…

Specifications for the 2SA1873 PNP transistor, provided as a 247 KB PDF. The 2SA prefix comes from the JIS semiconductor naming system and denotes a PNP bipolar part, so…

At 320 KB, this PDF for the 2SA1163 is the largest of this group of 2SA files and likely a full manufacturer datasheet with characteristic curves.

A 207 KB PDF for the 2SA1736, filed in the index as a schematic but named after a single semiconductor part rather than a board.

Specification document for the 2SA1728, provided as a 91.2 KB PDF with no board or device model in its name.

Indexed under schematics, this 26.9 KB PDF is labelled 2N6518, a JEDEC-registered discrete semiconductor designation.

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

Part number 2N5770 is the only detail this 296 KB PDF carries. It is listed as a schematic but names no board or laptop model.

Very small PDF of 26.3 KB named with the part number 2N5639 and nothing else. Listed as a schematic, it is most plausibly a short datasheet, since 2N codes are JEDEC…
