Short 28.5 KB PDF for the 2SJ364, written in lower case in the name and indexed as a schematic.

The 2SJ316 is the subject of this 91.5 KB PDF. Its name gives only the semiconductor type code, so no equipment model can be inferred.

Short PDF of roughly 41.2 KB for the 2SJ289. Nothing in the name besides the part number points to a specific device.

A compact 55.5 KB PDF covering the 2SD1304, catalogued as a schematic even though the 2SD number indicates a discrete NPN transistor under JIS numbering.

Part reference for the 2sd1275, written in lower case in the name and stored as a 56.4 KB PDF under schematics.

The 2SD1244 with an _E suffix is the subject of this 44.8 KB PDF, placed in the schematic category.

Datasheet-type file for the 2SD1237L, a 143 KB PDF listed under schematics. Per JIS numbering, 2SD identifies an NPN bipolar transistor for low-frequency work; the L…

The 2SD1229 is documented in this 126 KB PDF, which the index lists as a schematic. Its JIS number places it in the 2SD series of NPN bipolar transistors for…

Datasheet-type PDF for the 2SD1145 transistor, 89.8 KB, placed in the schematic category of the index.

The 2SD863 transistor datasheet, a 96 KB PDF with no maker named in the file title. JIS numbering identifies 2SD devices as NPN transistors aimed at low-frequency…

PDF component datasheet for the 2SD734 transistor, about 103 KB, filed under schematics though it documents a single part.

Part documentation for the 2SC5266A in PDF form, 182 KB, listed among schematics. JIS numbering makes 2SC an NPN bipolar transistor, while the A suffix generally…

Reference sheet for the 2SC4736 in PDF form, 104 KB in size. Although catalogued as a schematic, the number follows the JIS scheme where 2SC marks an NPN bipolar…

PDF reference sheet for the 2SC5243, 46.0 KB in size and indexed as a schematic, although the name suggests a transistor datasheet.

Compact 53 KB PDF for the 2SC4606, carrying an _E suffix that may mean an English edition, though the name does not say so explicitly.

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…

Compact 32.8 KB PDF labelled 2SC5645, filed among schematics but most probably a single-part datasheet for that transistor.

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.
