An 88.5 KB PDF on the 2SK1738 transistor. In the JIS system, 2SK designates an N-channel FET, so this file is most likely the datasheet rather than a circuit schematic.

The 2SK1489 named here is a discrete transistor code: under JIS numbering, 2SK denotes an N-channel field-effect transistor.

Reference PDF for the 2SK1457, filed under schematics and 122 KB in size. The file name carries only the part number.

The 2SK1456 is the only information in the name of this 124 KB PDF, which is indexed as a schematic.

Specification document for the 2SC5549 transistor, a 205 KB PDF in the schematic category.

The 2SC5540 transistor is covered by this 30.9 KB PDF, catalogued as a schematic. By JIS convention the 2SC prefix signifies an NPN bipolar device, so the document is…

Component data for the 2SC5531 NPN bipolar transistor, supplied as a 51.5 KB PDF and catalogued under schematics.

Datasheet-style PDF for the 2SC3988, 114 KB, filed in the schematic category though the name is a plain JIS transistor number.

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

Reference sheet for the 2SC5411, a PDF of 311 KB catalogued as a schematic. The name gives only the part number.

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

Part reference for the 2SC4987, provided as a 110 KB PDF and filed under schematics. No model, board or revision is stated in the name.

PDF of 41.0 KB titled 2SC4968 with an _E suffix whose meaning the name does not state. It is listed among schematics, but the 2SC prefix follows the JIS/JEITA…

Small 41.6 KB PDF for the 2SC5388, a JIS-numbered NPN bipolar transistor; the file name states only the part number, so package, maker and application are not given.

Covering the 2SC3914, this 30.1 KB PDF belongs to the family of JIS-numbered NPN bipolar transistors identified by the 2SC prefix.

Catalogued as a schematic, this 87.6 KB PDF is named only with the part number 2SC3808, which follows the Japanese JIS scheme where 2SC marks an NPN bipolar transistor…

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…

File name 2SC3786 offers nothing beyond a transistor type number, and the 81.5 KB PDF is placed in the schematic category.

PDF document labelled as a schematic but named after the 2SC5387, a Japanese-numbered NPN bipolar transistor part number, so in practice it is almost certainly the…

A 179 KB PDF for the 2SC3670, an NPN bipolar transistor by its JIS-style 2SC prefix. The name gives only the part number, with no device, board or revision, so treat it…

Data for the 2SC3576, an NPN transistor per the JIS 2SC designation, supplied as a 108 KB PDF and filed among schematics.

Small 39.7 KB PDF for the 2SC3526, carrying an _E suffix in its name whose meaning, perhaps a language edition or document revision, cannot be confirmed from the name…

Datasheet-type PDF of 43.3 KB for the 2SC5335, with an _E suffix that may denote an English version, though the name does not state it.

PDF document named after the 2SC5332 part number, filed here under schematics but most likely a component datasheet rather than a board diagram.

A 106 KB PDF for the 2SC3143, which the JIS 2SC designation marks as an NPN bipolar transistor.

Compact 102 KB PDF for the 2SC3090 transistor, indexed under schematics. The name carries no detail beyond the part code.
