PDF datasheet for the 4N35 optocoupler, marked as revision 2 in the file name and about 276 KB in size.

Filed as a schematic, this 44.1 KB PDF carries the name 2SD1450 with an _E suffix that the name does not explain; the part number points to a datasheet.

The 3N253 is documented in this 42.2 KB PDF, categorised as a schematic but evidently a discrete-component datasheet.

At 180 KB, this PDF named 2SD2449 is larger than most of its neighbours and is catalogued as a schematic.

PDF document of 49.5 KB named 2SD1996 followed by an E tag, filed under schematics. The 2SD prefix is the Japanese JIS designation for an NPN bipolar transistor, so this…

Datasheet-style PDF, 134 KB, for the 2SK2715, with a 1-5 suffix in the name whose purpose is not stated and may mark an edition.

PDF reference for the 2SK2551, a part named under the Japanese JIS scheme where 2SK identifies an N-channel field-effect transistor.

PDF datasheet, 298 KB, for the 2SK2037 N-channel FET, identified by its JIS 2SK prefix.

The 2SK1461 in the file name is a JIS-style code for an N-channel FET, so this 120 KB PDF, though listed as a schematic, is expected to be its datasheet.

PDF datasheet for the 2SK444, sized 92.5 KB and listed in the schematic category. The 2SK prefix places it in the Japanese JIS series of N-channel FETs, so the document…

Larger 225 KB PDF for the 2SK436, indexed as a schematic yet most likely a full datasheet with graphs and package dimensions, since 2SK numbers denote N-channel FETs…

Compact 29.9 KB PDF titled with the part number 2sk301 only. The 2SK prefix under JIS rules marks an N-channel FET, so this is best treated as a component data sheet…

A 139 KB PDF titled 2SJ507, placed in the schematic section of the index. The 2SJ prefix belongs to the JIS semiconductor scheme and denotes a P-channel FET, which…

Stored as a 149 KB PDF, this entry covers the 2SD1236L and sits in the schematic category, though the name points to a single transistor.

The 2SD1229 is documented in this 126 KB PDF, which the index lists as a schematic. Its JIS number places it in the 2SD series of NPN bipolar transistors for…

Compact 53 KB PDF for the 2SC4606, carrying an _E suffix that may mean an English edition, though the name does not say so explicitly.

Component documentation for the 2SC4425 in a 102 KB PDF. The JIS prefix 2SC denotes an NPN bipolar transistor, which points to datasheet content rather than a device…

Component sheet for the 2SC4410 with an unexplained _E suffix, delivered as a 41.6 KB PDF.

Named 2SC5637, this 42.7 KB PDF is listed as a schematic but is presumably the datasheet for that transistor.

Filed under schematics, this 117 KB PDF is named for the 2SC5563, a part number following the Japanese convention in which 2SC marks an NPN bipolar transistor.

A 477 KB PDF for the 2SC5087 part, an NPN bipolar transistor by its Japanese 2SC designation.

A 121 KB PDF named in lowercase after the 2SC3969 transistor and placed in the schematic section, though its content is most likely a part datasheet.

Datasheet-style PDF of 127 KB for the 2SC3708, an NPN transistor according to its JIS 2SC prefix, although the index files it as a schematic.

Reference PDF of 175 KB for the 2SC2235, a JIS-style designation where 2SC denotes an NPN bipolar transistor.

Reference sheet covering the 2SB1411 transistor, delivered as a 216 KB PDF. The larger size suggests it may contain characteristic curves or several pages, though the…

The name 2SA2025 on this 38.7 KB PDF is a JIS transistor number; the 2SA prefix means a PNP bipolar device.

The 2SA1259 PNP transistor is the subject of this 43.4 KB PDF, which the index files as a schematic.

Part reference for the 2SA1208 as a 44.3 KB PDF, placed in the schematic category though nothing in the name goes beyond the component number; expect datasheet content.

Component datasheet for the 2SA1803, provided as a 179 KB PDF and indexed with schematics. The 2SA prefix places it among PNP bipolar transistors under the JIS standard.
