A 139 KB PDF for the 2SK2623, which JIS numbering identifies as an N-channel FET. Although indexed as a schematic, it is effectively a component datasheet with limits…

A short 28.8 KB PDF for the 2SK2379, indexed as a schematic though it is almost certainly a component datasheet; JIS numbers starting with 2SK denote N-channel…

Titled 2SK2378, this 26.7 KB PDF is the smallest in its series and is listed under schematics, but the JIS part number indicates a datasheet for an N-channel FET.

The 2SK2094 N-channel FET is the subject of this 127 KB PDF, which is catalogued as a schematic though the bare part-number name points to a datasheet.

Reference sheet in PDF form (98.9 KB) for the 2SK1909 transistor, catalogued under schematics.

Small 36.4 KB PDF for the 2SK1614, an N-channel field-effect transistor according to the Japanese 2SK designation.

A 109 KB PDF for the 2SK1439, filed with schematics but most likely the manufacturer's data sheet for this transistor. The JIS 2SK prefix denotes an N-channel FET.

The 2SK1420, an N-channel FET according to the Japanese JIS 2SK prefix, is the subject of this 103 KB PDF.

The 2SK1413 is documented in this 112 KB PDF, listed under schematics but named after a single discrete part, which points to a datasheet.

Reference datasheet for the 2SK1052, delivered as a 104 KB PDF with no other details in the name.

The largest of this group at 400 KB, this PDF is named for the 2SK241 and filed as a schematic.

A 294 KB PDF for the 2SK209, filed as a schematic. In JIS semiconductor nomenclature the 2SK series is N-channel FETs, so this is effectively a component datasheet.

A 32.3 KB PDF for the 2SJ591LS, filed under schematics but named like a transistor datasheet.

The 2SJ349 P-channel FET is described in a 418 KB PDF, catalogued under schematics though it is a component datasheet.

The 2SJ305 is described in this 335 KB PDF, listed among schematics. No board number or brand appears in the name.

PDF reference of about 107 KB for the 2SJ285, filed in the schematic category. The name gives nothing beyond the component type.

Reference PDF for the 2SD1197 transistor, 134 KB in size and indexed as a schematic, though the file name is only a part number and reads as a datasheet.

The name carries only the part number 2SD1195, so this 148 KB PDF is best treated as the datasheet for that transistor, even though the index labels it a schematic.

Transistor reference for the 2SC5262, delivered as a 126 KB PDF and catalogued as a schematic.

The 2SC4685 is documented in this 186 KB PDF, filed as a schematic though the name is a transistor part number.

Transistor documentation for the 2SC4678 in a 220 KB PDF file, sorted into the schematic category.

A 102 KB PDF for the 2SC4635, a JIS-designated NPN transistor, most likely the full datasheet; a companion LS-variant file exists in the same series.

Here is a 178 KB PDF for the 2SC5254, a Japanese JIS-registered NPN bipolar transistor, most probably its datasheet.

Datasheet for the 2SC4605 in a 241 KB PDF, larger than most in this series and so likely to include more curves or package drawings.

Filed as a schematic, this 192 KB PDF carries just the identifier 2SC5172, which indicates a datasheet for a discrete NPN bipolar transistor following the JIS 2SC naming…

Filed as a schematic, the 124 KB PDF titled 2SC4555 names a discrete transistor, so its content is probably the datasheet.

A 154 KB data sheet in PDF form describing the 2SC4488. Under JIS naming, the 2SC prefix denotes an NPN bipolar transistor, and the file covers that single component…

Covering the 2SC4483, this 126 KB PDF is a semiconductor data sheet; the 2SC prefix follows JIS rules for NPN bipolar transistors.

Reference PDF, 106 KB, for the transistor numbered 2SC4407. The 2SC prefix follows the Japanese JIS standard for NPN bipolar transistors, indicating datasheet content…

Here is a 297 KB PDF named 2SC5590, sorted under schematics but bearing only a component number, so it should be the datasheet for that part.

Filed among schematics, this 467 KB PDF carries just the transistor number 2SC4320 and should be regarded as its datasheet.
