Small 57.3 KB PDF for the 2SC5060, filed under schematics though the name suggests a transistor part sheet.

PDF for the 2SC1172, 74.4 KB, listed among schematics with no further detail in its name.

PDF for the BU4508DX, a small 48.8 KB document filed as a schematic but most likely the part datasheet.

PDF of 77.6 KB named 2SD1620 and filed with schematics; the name carries nothing beyond the part number, which points to a component datasheet.

Smaller 137 KB PDF tied to the 2SK2606, a JIS-style designation where 2SK indicates an N-channel field-effect transistor.

The 2SJ339 appears in this small PDF of roughly 40.7 KB. The name carries only the part number, with no hint of the equipment it came from.

Catalogued as a schematic, this 41.7 KB PDF bears the part number 2SC5611 and should be the datasheet for that NPN bipolar transistor.

Indexed as a schematic, this 91.5 KB PDF named 2SC4390 is most likely the datasheet of that NPN bipolar transistor.

Datasheet-style PDF for the 2SC4271 transistor, catalogued here under schematics and weighing 78.2 KB. The name gives only the part number, with no maker or revision.

A 107 KB PDF covering the 2SC4270, a JIS-numbered part. The 2SC prefix denotes an NPN transistor intended for high-frequency use.

PDF reference for the 2SC4257 transistor, 81.6 KB, filed under schematics although it is a part document rather than a board drawing.

Datasheet PDF for the 2SC5575, 52.0 KB, placed in the schematic section of the index. The file name contains only the part number.

Indexed as a schematic, this 296 KB PDF is named only 2SC5094, a JIS-style transistor designation where 2SC stands for an NPN device rated for high-frequency operation.

Small 46.2 KB PDF for the 2SC5501. Under the Japanese JIS scheme, a 2SC prefix marks an NPN transistor intended for high-frequency use.

Covering the 2SC5028, this 219 KB PDF is filed as a schematic yet is named like a component datasheet.

Covering the 2SC5019, this 41.9 KB PDF carries an _E suffix and is indexed as a schematic.

Datasheet PDF for the 2SC3931, 60.7 KB, with the _E suffix common to this group of files and listed as a schematic.

The 2SC3922 is the subject of this short 30.5 KB PDF, listed as a schematic with no suffix or revision in its name.

A 41.3 KB PDF named 2SC5018 with an additional _E suffix that the name does not explain.

Indexed as a schematic, this 195 KB PDF carries just the type number 2SC3803. In JIS semiconductor naming, 2SC stands for an NPN transistor, so the content is most…

Datasheet-type PDF for the 2SC4787, a JIS-numbered NPN transistor, filed in the schematic category.

Short 108 KB PDF datasheet for the 2SC3601, placed in the schematic section of the index.
