Raw BIN image of 32.0 MB named 32MB new, with no brand, model or board number given, so the target device is unknown.

Here the subject is the 2SD2167, delivered as a 51.2 KB PDF filed as a schematic. By JIS convention the 2SD prefix belongs to NPN bipolar transistors for low-frequency…

Datasheet PDF, 413 KB, referencing the 2SK2601, catalogued as a schematic. Per JIS semiconductor naming, the 2SK prefix denotes an N-channel FET; no other details such…

Covering the 2SK2507, this 422 KB PDF belongs to the JIS family of N-channel field-effect transistors denoted by the 2SK prefix.

Sized at 111 KB, a PDF for the 2SK2394 that the index lists under schematics, though its JIS-style part number indicates a datasheet for an N-channel field-effect…

The 2SK1867 is named in this small 33.9 KB PDF, catalogued under schematics. Because 2SK is the Japanese prefix for N-channel field-effect transistors, expect a brief…

Short 36.3 KB PDF on the 2SK1803. Part numbers prefixed 2SK are N-channel field-effect transistors in the Japanese JIS registration system, and this file is most likely…

Part datasheet in PDF form for the 2SK1727, about 86 KB. Its 2SK prefix marks an N-channel FET under the Japanese transistor naming system; manufacturer, package and…

Named after the 2SJ190, this 93.3 KB PDF sits in the schematic category but, given the JIS 2SJ prefix for P-channel field-effect transistors, should contain the…

At 330 KB, this PDF named 2SJ168 is the largest in its series and likely a fuller datasheet for that JIS-numbered P-channel field-effect transistor, possibly with…

Filed as a schematic, this 72.9 KB PDF is titled 2SD1398; in the Japanese JIS scheme the 2SD prefix marks an NPN bipolar transistor intended for low-frequency use, so…

Datasheet-style document for the 2SC4617, marked revision 0 in the file name and stored as a 128 KB PDF under the schematic category.

Datasheet PDF, 52.4 KB, for the 2SC5574, with the type number written in lowercase in the original name.

Datasheet for the 2SC4214 transistor, supplied as a 279 KB PDF. The file name holds nothing beyond the part number, so the manufacturer, package and target equipment…

Documentation for the 2SC5548 NPN bipolar transistor, a 231 KB PDF catalogued under schematics, with a separate 2SC5548A variant also present in the collection.

Filed as a schematic, the 112 KB document 2SC5046 is really labelled with a Japanese NPN transistor part number, which suggests a single-component datasheet.
