PDF for the 2SK1238, a Japanese 2SK-series N-channel MOSFET, size 45.9 KB. No manufacturer, package or revision appears in the file name, so match the printed marking on…

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.

Filed under schematics, this 84.0 KB PDF carries only the part number 2SD1153 in its name and should be a transistor datasheet.

PDF datasheet for the 2SD1133, 43.0 KB, listed among schematics though its name refers only to the part.

Datasheet-style PDF, 99.8 KB, for the 2SC5296 transistor. Under Japanese JIS naming, 2SC parts are NPN bipolar types, so expect specifications rather than a full circuit…

Compact 27.2 KB PDF on the 2SC5291. The 2SC prefix identifies an NPN bipolar transistor in the JIS system, so this is most likely a short manufacturer datasheet, filed…

The 2SC5273 is the subject of this 42.0 KB PDF. As a JIS-registered 2SC device it is an NPN bipolar transistor, and the file is likely its datasheet rather than a full…

A 35.0 KB PDF relating to the 2SC5270. The 2SC prefix denotes an NPN bipolar transistor in the Japanese JIS system, so the document is most probably a compact datasheet…

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

The 2SC4735 is covered by this 109 KB PDF, listed under schematics but named purely by part number.

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.

Here is the 106 KB datasheet-style PDF for 2SC4637, a JIS-numbered NPN bipolar transistor.

This 28.6 KB PDF carries the part number 2SC4635LS, apparently a package or lead-form variant of the 2SC4635 NPN transistor.

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.

PDF file of 129 KB titled with the part number 2SC5228, catalogued as a schematic but best treated as a transistor datasheet.

PDF reference, about 137 KB, for the 2SC4614 transistor. Although categorised as a schematic, a bare part-number name like this normally indicates a datasheet rather…

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.

Datasheet-type PDF, about 236 KB, for the 2SC5176 transistor, catalogued as a schematic though the name contains only the part number.

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…

2SC4579 datasheet candidate in PDF form, 102 KB, categorised as a schematic. The name follows the JIS convention in which 2SC denotes an NPN bipolar transistor for…

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

For the 2SC4489 NPN bipolar transistor, as indicated by the JIS 2SC prefix, this 154 KB PDF serves as the component datasheet even though it is catalogued under…

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.

Datasheet candidate for the 2SC4455 transistor, a 100 KB PDF although filed with schematics.

Named after transistor 2SC4452, this 98.8 KB PDF is listed as a schematic but most likely contains the component datasheet.

The smaller 77.9 KB PDF here carries the type number 2SC4449, indexed as a schematic but almost certainly a component datasheet.

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

PDF of 51.8 KB for the 2SC5610 transistor, indexed with schematics although the bare part number suggests a manufacturer datasheet.

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.
