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.

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.

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.

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…

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.

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, 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.

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

A 249 KB PDF for the 2SC4203, filed as a schematic but named with only a semiconductor type number.

The 2SC5459 comes as a 186 KB PDF in the schematic category, though the part number, a JIS 2SC NPN transistor, points to a datasheet.

Named after the 2SC5707, this 37.8 KB PDF should be a datasheet for an NPN bipolar transistor, as the 2SC prefix indicates under JIS numbering.

Small 28.7 KB PDF for the 2SC5699 transistor. Per JIS convention, the 2SC prefix identifies an NPN bipolar device, so the file is likely a short datasheet.

Datasheet for the 2SC5698, 29.1 KB in PDF form, belonging to the JIS 2SC family of NPN bipolar transistors. The name carries only the part number.

At 109 KB, this PDF is named after the transistor 2SC5047. It is catalogued as a schematic, but the JIS 2SC prefix indicates an NPN bipolar part, so it is best read as a…

This 106 KB PDF carries the part number 2SC5044 and is catalogued as a schematic. Since the 2SC prefix in the Japanese JIS system marks NPN transistors, the content is…

The 102 KB PDF 2SC5041 is indexed under schematics, though its name is just a 2SC part number, the Japanese JIS code for an NPN bipolar transistor, so treat it as a…

Datasheet PDF, 41.0 KB, covering the 2SC3954, a JIS-numbered NPN bipolar transistor, and listed in the schematic category.

Datasheet-type PDF for the 2SC3912, sized at 30.2 KB. The part number follows the JIS standard, where 2SC identifies an NPN bipolar transistor; the name offers no…

The 2SC3901 transistor is documented in this 88.3 KB PDF. Following the JIS convention, the 2SC prefix denotes an NPN bipolar device, so the file is most plausibly its…
