Reference sheet for the 2SJ345 in PDF format, about 333 KB. The name gives only the part number, with no board or device information.

PDF for the 2SJ306, about 94.4 KB. The name contains just the transistor type, so no device, board or revision can be stated.

UTC datasheet covering the 2SD882L, a variant of the widely used 2SD882 NPN transistor, stored as a small PDF of about 24 KB.

Specification sheet for the 2SD874 transistor in PDF form, about 44 KB, catalogued with the schematics but actually a component datasheet.

At 464 KB, this PDF for the 2SC5264 is the largest of the related transistor files and is likely a full datasheet with characteristic curves.

Datasheet-type PDF of 220 KB for the 2SC5260, carried in the schematic section of the index.

The part number 2SC4473 is the only information in this 122 KB PDF name, and it identifies a Japanese JIS-coded NPN transistor of the high-frequency type.

Reference sheet in PDF format for the 2SC4256, 80.8 KB in size. The file name gives no manufacturer, package or revision details.

Part number 2SC4223 is all the file name gives, so this 93.9 KB PDF is best treated as a datasheet for that component rather than a circuit schematic.

At 108 KB, this PDF is labelled with the transistor type 2SC4221 and nothing else, so no board, model or revision is identified.

Filed in the schematic section, this 156 KB PDF is named for the 2SC4135, which by JIS convention is an NPN bipolar transistor, so expect a component datasheet inside.

Covering the transistor 2SC4104, this compact 19.1 KB PDF is tagged as a schematic, but the 2SC prefix in Japanese JIS numbering identifies an NPN bipolar device, so…

PDF for the 2SC4061K, 61.7 KB, filed under schematics though the name reads as a component datasheet.

Datasheet-type PDF, 58.1 KB, bearing the part number 2SC4027 and stored under schematics. Under the Japanese JIS scheme the 2SC prefix means an NPN bipolar transistor.

PDF sheet for the 2SC3935 part, with an _E suffix after the number, filed under schematics at 40.7 KB.

Filed under schematics, this 466 KB PDF is identified by the code 2SC4839 alone. In the Japanese JIS designation system the 2SC prefix belongs to NPN bipolar…
