Datasheet-style PDF named for the 2SC4430, sized 108 KB and listed as a schematic in the index.

PDF file of roughly 104 KB identified only by the part number 2SC4424. Under the Japanese JIS numbering scheme, 2SC parts are NPN bipolar transistors, so the document…

PDF documentation for the 2SC5149, the largest of this batch at 193 KB. Under the Japanese JIS scheme the 2SC prefix denotes an NPN bipolar transistor, so the content…

The largest of this group at 465 KB, the PDF named 2SC4394 is most likely a full datasheet for that transistor rather than a board schematic, despite its index label.

Datasheet in PDF format for the 2SC5583, 46.0 KB in size. The file name states the part number and nothing else.

The 2SC4249 transistor is the subject of this 263 KB PDF, filed under schematics. The name carries the part number alone, so maker and revision are not stated.

Part documentation in PDF form for the 2SC4245, 335 KB, catalogued in the schematic category. The file name gives only the part number without maker, package or version.

Component documentation for the 2SC4220, delivered as a 106 KB PDF and filed under schematics.

Device datasheet in PDF form, 297 KB, for the 2SC5096, though the catalogue lists it as a schematic.

PDF file of 466 KB covering the 2SC5090 part, a JIS-registered NPN bipolar transistor going by its 2SC prefix.

PDF for the 2SC5532, 47.0 KB, indexed as a schematic and written in lowercase in the original name.

Datasheet for the 2SC3965 NPN transistor, a 40.3 KB PDF listed as a schematic. The trailing _E in the name commonly marks an English-language edition of a Japanese…

Bearing only the number 2SC3785, this 84.2 KB PDF is indexed as a schematic, though the JIS 2SC prefix identifies an NPN bipolar transistor and suggests a datasheet…

Indexed in the schematic section, this 91.7 KB PDF provides reference data for the 2SC3688, an NPN transistor under JIS naming.

Filed in the schematic category, this 403 KB PDF concerns the 2SC3672 transistor, making it the biggest file in this batch.

A 320 KB PDF dealing with the 2SC3123, an NPN bipolar transistor by its Japanese JIS 2SC code.

Reference sheet for the 2SC2792, supplied as a 186 KB PDF and listed in the schematic category, although the name points to a component datasheet.

At 526 KB, this PDF for the 2SC1923 is larger than most single-part sheets in the set, possibly including more curves or package options.

Small 40.2 KB PDF named after the 2SC1756, filed in the schematic category. The JIS-style 2SC designation identifies an NPN bipolar transistor, so expect a concise…

Part number 2SB1209 with an _E suffix identifies this 42.6 KB PDF, filed under schematics though a single-part document of this kind is normally a datasheet.

At 262 KB this is the largest file in the batch, a PDF for the 2SA1432 transistor, likely holding graphs and package drawings as well as the rating tables.
