PDF of 75.0 KB covering the 2SD2176 part. Though listed as a schematic, a file named after a single JIS transistor number is most likely a datasheet, and the 2SD prefix…

Single-part PDF of 47.0 KB for the 2SD2583, listed as a schematic but most probably a datasheet.

Part 5LP01N is documented in this 27.9 KB PDF, filed under schematics. The name is limited to the part code; in this family LP appears to designate a P-channel MOSFET…

Component documentation for the 4N38 optocoupler, filed under schematics though it is in practice a part datasheet in PDF form of about 140 KB.

Part reference for the 2SD1669, supplied as a 107 KB PDF and filed in the schematic section.

Transistor documentation for the 2SD1667, 136 KB in PDF format. Nothing beyond the part number appears in the name.

PDF of 119 KB for the 2SD1664, written in lowercase in the original name and filed as a schematic.

The 2SD1628 is covered in this 88.3 KB PDF, catalogued with schematics though it relates to a single transistor.

Indexed as a schematic, this 109 KB PDF is titled 2SD1621, a transistor part number, so treat it as a datasheet rather than a circuit diagram.

Part number 2SD1424 with an unexplained _E suffix names this 41.4 KB PDF, indexed among schematics but most likely a datasheet for the transistor.

Small 33.0 KB PDF for the 3SK144, catalogued as a schematic but named for an individual semiconductor, so it is most likely a datasheet.

Document for the 3SK227 semiconductor, stored as a 30.6 KB PDF and catalogued under schematics.

Short 54.7 KB PDF for the 2SD1991A, an NPN bipolar transistor going by its JIS 2SD prefix. The index lists it under schematics.

Tiny 30.2 KB PDF named 2sk65, a JIS part number that indicates a component datasheet, although it is filed as a schematic.

Covering the 2SK3335, this small PDF (32.6 KB) is a part datasheet placed in the schematic category.

PDF reference for the 2SK2749 transistor, 412 KB, stored in the schematic section. Under Japanese JIS numbering the 2SK prefix identifies an 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.

Reference PDF for the 2SK2714 transistor, 144 KB, filed in the schematic section. JIS naming uses 2SK for N-channel field-effect transistors, so the contents should be a…

Brief 34.7 KB PDF for the 2sk2581 transistor, catalogued as a schematic. JIS naming assigns 2SK to N-channel field-effect transistors, and the name gives no further…

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

Brief PDF, about 30.2 KB, for the 2SK2509, a JIS-designated N-channel FET as indicated by its 2SK prefix.

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

For the 2SK1905 N-channel field-effect transistor, this PDF of 92.7 KB is indexed under schematics, though a bare part number in the name points to a datasheet.

Part 2SK1890, documented in a 96.7 KB PDF placed in the schematic category. Japanese JIS numbering reserves 2SK for N-channel FETs, so this is a component datasheet…

At 120 KB, this PDF is a slightly larger reference for the 2SK1728. Japanese JIS/JEITA numbering assigns the 2SK series to N-channel field-effect transistors, so expect…

Sheet for the 2SK1310A, an N-channel field-effect transistor in the Japanese 2SK series, supplied as a 175 KB PDF.
