Reference sheet for the 2SD2116 NPN transistor, supplied as a 74 KB PDF. Its name follows the Japanese JIS 2SD convention and carries nothing beyond the part number.

The 2SD1622 PDF, 138 KB in size, sits among schematics, but a file named only by a semiconductor part number is very likely the device datasheet.

Datasheet PDF for the 2SD1979, filed under schematics at 42.4 KB. The 2SD prefix follows JIS convention for NPN bipolar transistors of the low-frequency class, and the E…

The 2SK3121 is covered by this 126 KB PDF, which the index lists as a schematic although it serves as a part datasheet.

Part 2SK2399 is the subject of this 423 KB PDF, catalogued as a schematic but in all likelihood a datasheet, since under Japanese JIS numbering 2SK stands for an…

The 2SK1613 transistor is covered by this 36.4 KB PDF. In Japanese JIS/JEITA numbering the 2SK prefix denotes N-channel FETs, making this a component datasheet rather…

Indexed under schematics, this 110 KB PDF carries the part number 2SK1447 and is likely its full component data sheet.

Datasheet-style PDF for part 2SK303, about 101 KB, listed in the schematic category. In JIS semiconductor naming, 2SK designates N-channel field-effect transistors.

The 2SJ619 is the subject of this 314 KB PDF, indexed as a schematic though the naming suggests a component datasheet.

Roughly 96.6 KB PDF named for the 2SJ308. The name is limited to the part number and provides no model or board reference.

Listed under schematics, this 110 KB PDF is named for the 2SD1347, an NPN bipolar transistor in the Japanese JIS 2SD series, and is probably its datasheet.

For the 2SD893, this 53.8 KB PDF includes an _E suffix in its name whose meaning is not given.

PDF datasheet for the 2SD879 transistor, roughly 106 KB, with no manufacturer indicated in the file name.

The 2SC4527 data sheet, a 310 KB PDF filed under schematics but in practice a component specification.

A 92.1 KB PDF labelled 2SC4106 and placed among the schematics. The name carries no model or board number, only the part designation; in the Japanese JIS/JEITA system…

A brief 37.5 KB PDF identified only by the part number 2SC5710. JIS numbering assigns 2SC to NPN bipolar transistors, so this is likely a concise datasheet.

Datasheet in PDF for the 2SB1558 transistor, roughly 185 KB, listed under schematics. The 2SB designation follows the Japanese JIS standard for PNP low-frequency bipolar…

The 2SA1621 is covered by this 194 KB PDF, listed among schematics but really describing one discrete semiconductor.

Labelled 2sb1197k, this 76.0 KB PDF refers to a JIS-registered transistor whose number includes a K suffix; although filed under schematics it should be the datasheet.

A 90.4 KB PDF describing the 2SA1423, identified only by part number. By Japanese JIS convention the 2SA prefix marks a PNP transistor.

The 2SA1370 is a PNP transistor in the Japanese JIS numbering system, and this 138 KB PDF is named after it alone.

PNP bipolar transistor 2SA1313, named under the Japanese JIS scheme, is documented in this 207 KB PDF.

Compact 40.8 KB PDF for the 2SA1257, indexed as a schematic though its name carries only a part number.

A 444 KB PDF for the 2N7000 carrying the tag Sam, which probably identifies the manufacturer that issued it, although the name does not expand the abbreviation.

Indexed in the schematic section, this 115 KB PDF is named 2N6346A, a JEDEC 2N-series discrete semiconductor number with an A suffix that usually marks a variant of the…

Compact 51.7 KB PDF documenting the 2N4036, filed under schematics though its JEDEC-style name indicates a discrete component datasheet.

Small 33.9 KB PDF datasheet for the 2N3415, a JEDEC-registered 2N-series transistor, labelled as a schematic. The name gives only the part number.
