PDF datasheet, 40.9 KB, for the 2SD2240 transistor, filed under schematics in this index. An _E suffix in the name is an edition marker for the document only.

Compact 43.6 KB PDF named for the 3N249 and filed as a schematic, although it is almost certainly a component datasheet.

Catalogued as a schematic, the 40.9 KB PDF 2SD2413 with an E tag relates, by the JIS 2SD prefix, to an NPN bipolar transistor rather than a complete board.

Part reference for the 2SK2782, delivered as a 419 KB PDF under the schematic label. The 2SK prefix follows Japanese JIS numbering for N-channel field-effect…

The 2SK2718 is documented in a 412 KB PDF that the catalogue files under schematics, though by its name it is a component datasheet.

PDF documentation for the 2SK2544 N-channel FET, following the Japanese JIS 2SK naming pattern, with a file size of 409 KB.

Document for the 2SK2400, 403 KB in PDF format and listed as a schematic, although the name points to a single-component datasheet.

Part number 2SK2231 is the only information carried by this 420 KB PDF, which the index places among schematics but which most likely documents a single transistor.

PDF document for the 2SK1921, filed under schematics although the name is simply a semiconductor part number.

Compact 33.4 KB PDF for the 2SK1374, a Japanese-numbered N-channel MOSFET. Only the part number appears in the file name, so the issuing manufacturer and exact package…

The 2SJ377 is covered by this 415 KB PDF, a component datasheet filed in the schematic category.

The name of this 92.4 KB PDF consists only of 2SJ255, a Japanese JIS designation where 2SJ marks P-channel FETs.

PDF sheet titled only with the part number 2SC5022, 42.0 KB, placed under schematics. No suffix, revision or maker appears in the name.

Datasheet PDF for the base 2SC5417, 45.9 KB, filed in the schematic section; a separate LS-suffixed variant exists in the same set.

Specification document for the 2SC4782 transistor, saved as a 46.9 KB PDF whose _E ending likely marks an English version.

Small 41.7 KB PDF for the 2SC5346; the _E suffix possibly marks an English edition, though the name alone cannot confirm this.

Catalogued as a schematic, this 49 KB PDF is named after the 2SC2613, a part number in the Japanese JIS scheme, where the 2SC prefix marks an NPN bipolar transistor.

By Japanese JIS numbering the 2SB643 is a PNP bipolar transistor, so this 44.2 KB PDF labelled as a schematic should be its datasheet, with _E probably marking an…

PDF reference for the 2SA1574 transistor, 47.9 KB in size. Apart from the part number, the name says nothing about package, maker or revision.

The 2sb1189 part number names this 42.5 KB PDF, which is placed in the schematic category but is most probably the transistor datasheet.
