A 169 KB PDF for the 2SD1803, placed in the schematic category but evidently a component reference sheet. No manufacturer, revision or variant is named.

This 91.1 KB PDF covers the 2SD1887 transistor; it sits in the schematic category but the file name matches a JIS component designation, pointing to a datasheet.

Datasheet PDF for the 2SK2889, 417 KB in size and indexed here under schematics. The name states nothing beyond the part number.

PDF of 426 KB named for the 2SK2842 part number and filed in the schematic category. Because the 2SK prefix denotes an N-channel field-effect transistor in JIS…

Document for the 2SK2841, a JIS-style part number whose 2SK prefix marks an N-channel FET.

A 137 KB PDF for the 2SK2714 with a 1-5 suffix that the name leaves unexplained, possibly an edition or page range.

The smallest of this group at 23.0 KB, this PDF covers the 2sk2474, a JIS-numbered N-channel FET.

Listed among schematics, this 31.7 KB PDF refers to the 2SK2340, a Japanese JIS-numbered device where 2SK designates an N-channel field-effect transistor.

Part number 2SK1906 is all the name reveals about this 96.0 KB PDF, which sits in the schematic category.

The 2SK1266 N-channel field-effect transistor is documented in this 33.9 KB PDF, indexed as a schematic.

Here the 2SK1234 N-channel field-effect transistor is described in a 46.1 KB PDF. The 2SK code marks it as an N-channel device under the Japanese JIS scheme, used in…

At 151 KB, this 2SK543 PDF is one of the larger sheets in the series, probably including detailed characteristic curves and package dimensions.

Reference sheet for the 2SJ620 in PDF form, 345 KB, listed in the schematic category. The 2SJ prefix follows the Japanese JIS scheme for P-channel field-effect…

Datasheet-like PDF, 42.5 KB, for the 2SJ583LS and filed as a schematic. Japanese JIS designations starting with 2SJ belong to P-channel FETs, and the LS suffix points to…

Named 2SJ503, this 87.9 KB PDF is tagged as a schematic but most likely contains a transistor datasheet, because 2SJ is the Japanese JIS designation for P-channel…

A compact 27.8 KB PDF named after 2SJ164, a JIS designation identifying a P-channel FET.

Compact 44.8 KB PDF for the 2SD1051, with an _E suffix in the name whose meaning is not stated, possibly a language or edition marker.

Specification sheet for the 2SD874 transistor in PDF form, about 44 KB, catalogued with the schematics but actually a component datasheet.

A small 49.5 KB PDF for the 2SC4767 part, filed as a schematic; the trailing _E in the name is not explained, so check the document to see what it denotes.

At 153 KB, this PDF named 2SC4399 is presumably the datasheet for that NPN bipolar transistor, even though the index lists it as a schematic.

Filed as a schematic, this 59.7 KB PDF is titled 2SC5128 and presumably holds the datasheet of that NPN bipolar transistor.

Component documentation for the 2SC4269 in PDF form, 108 KB in size, listed in the schematic category. Nothing beyond the part number appears in the name.

PDF part sheet for the 2SC5577, 40.7 KB, catalogued with schematics. The name gives only the part number and says nothing about the maker or revision.

A 305 KB PDF for the 2SC4246 transistor. The name states nothing apart from the part number, so the manufacturer and revision have to be read inside the document.

At 108 KB, this PDF is labelled with the transistor type 2SC4221 and nothing else, so no board, model or revision is identified.

A 128 KB PDF identified solely by the transistor number 2SC4218. JEITA naming assigns 2SC to NPN bipolar transistors, so despite the schematic label this is most…

Small 30.8 KB PDF covering the 2SC3919, one of a numbered run of similar sheets in this index.

Filed under schematics, this 466 KB PDF is identified by the code 2SC4839 alone. In the Japanese JIS designation system the 2SC prefix belongs to NPN bipolar…

Only the type number 2SC4836 appears in the name of this 110 KB PDF, indexed as a schematic.

Specifications for the 2SC3656 in PDF form, 90.4 KB. Parts beginning with 2SC in the JIS system are NPN bipolar transistors.

Named only after the JIS transistor number 2SC3461, this 110 KB PDF is listed as a schematic but is most probably a single-part datasheet.

Named simply 2SC3399, this 86.9 KB PDF refers to a Japanese-registered NPN transistor; the 2SC prefix under JIS indicates a high-frequency type.

Only the part number 2SC3361 appears in the name of this 129 KB PDF, so no equipment or board can be identified from it.

The 2SC3144 NPN transistor is documented in this 117 KB PDF, filed as a schematic though it is most likely a component data sheet.

A 94.9 KB PDF for the 2SC3088, filed as a schematic but in practice probably a component datasheet. Its name contains just the part number.
