Component reference for the 2SD1993, a 45.5 KB PDF listed among schematics. Following Japanese JIS part numbering, 2SD identifies an NPN bipolar transistor of the…

Part documentation for the 2SK2914 in PDF form, 396 KB, placed in the schematic section of the index.

Covering the 2SK2865, this 424 KB PDF sits in the schematic category but, judging by its name, is the component datasheet.

Part reference for the 2SK2607, an N-channel FET according to the 2SK prefix of the JIS numbering convention.

Short 34.8 KB datasheet-style PDF for the 2sk2576, an N-channel FET under the Japanese JIS 2SK designation.

Component documentation in PDF format, 32.4 KB, for the 2SK2326. The 2SK prefix follows the JIS registration scheme and signifies an N-channel FET, so despite the…

A PDF of about 88 KB for the 2SK2154, filed under schematics but most likely a component datasheet, since the name is just the part number.

Datasheet in PDF form for the 2SK1067, a member of the 2SK family of N-channel FETs, at 144 KB. The file carries no further details in its name.

Datasheet-style PDF of 105 pages' worth of nothing more than a part number: the 2SJ420, a device whose 2SJ prefix under Japanese JIS designation identifies a P-channel…

A 92.5 KB PDF named after 2SJ256, a JIS-numbered P-channel field-effect transistor according to its 2SJ prefix.

A 92.7 KB PDF catalogued under schematics but titled only 2SJ228, a JIS-style designation used for P-channel FETs.

Small 89.2 KB PDF labelled 2SJ191, a JIS designation that marks a P-channel FET, so the file is presumably that part's datasheet rather than a board schematic.

The 2SC4690 is the subject of this 175 KB PDF, which the index files as a schematic even though the name points to a single transistor document.

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

Datasheet-style PDF of 119 KB for the 2SC4401, listed in the index under schematics although the name points to a single semiconductor part.

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

Compact 43.3 KB PDF covering the 2SC5551, a JIS-coded NPN bipolar transistor, even though the catalogue type says schematic.

A 45.1 KB PDF listed under schematics for the 2SC5448, a part number that under the Japanese JIS scheme identifies an NPN bipolar transistor.

Here is a 49.4 KB PDF for part 2SC4067, placed under schematics but named like a manufacturer datasheet.

Catalogued as a schematic, this 100 KB PDF is named after the 2SC4031 and is most likely its datasheet. JIS numbering uses 2SC for NPN bipolar transistors.

Datasheet PDF, 81.8 KB, for the 2SC3997 transistor, placed in the schematic listing. JIS numbering uses 2SC for NPN bipolar transistors; nothing else, such as maker or…

A 52.6 KB PDF for the 2SC3933, labelled with an _E suffix and catalogued as a schematic.
