Part reference for the 2SK2782, delivered as a 419 KB PDF under the schematic label. The 2SK prefix follows Japanese JIS numbering for N-channel field-effect…

PDF reference for the 2SK2749 transistor, 412 KB, stored in the schematic section. Under Japanese JIS numbering the 2SK prefix identifies an N-channel field-effect…

Brief PDF, about 30.2 KB, for the 2SK2509, a JIS-designated N-channel FET as indicated by its 2SK prefix.

The 2SK2504 transistor is documented in this 134 KB PDF, named in lowercase and catalogued under schematics.

The 2SK2267 named here is an N-channel FET under the Japanese JIS/EIAJ scheme, where 2SK denotes that transistor class.

Only the part number 2SK2221 names this small 55 KB PDF, which is catalogued as a schematic but most likely serves as a component datasheet.

Reference sheet for the 2SK937 transistor, a 79.9 KB PDF. Parts in the 2SK range are N-channel field-effect transistors under the Japanese JIS designation.

Datasheet-type PDF for the 2SK536, 60.8 KB, catalogued under schematics. Under the Japanese JIS system the 2SK designation means an N-channel FET, so the content…

For the 2SJ579, this 42.7 KB PDF is indexed as a schematic, but a bare part-number name typically marks a datasheet.

Here is a 151 KB PDF for the 2SD1230, filed under schematics although it relates to one transistor type.

For the 2SD1011, this 42.1 KB PDF carries an _E tag in the name with no stated meaning.

Here is a 144 KB PDF for the 2SC4728, filed as a schematic but carrying a discrete part number.

A 247 KB PDF titled only with the part number 2SC4667, catalogued here as a schematic. The 2SC prefix is the JIS code for an NPN transistor intended for high-frequency…

Here is the 2SC5242 documentation as a 173 KB PDF, placed in the schematic category but evidently a part datasheet going by its name.

Documentation for the 2SC4781 in a 120 KB PDF, indexed as a schematic though the name matches a discrete semiconductor part.

Part datasheet for the 2SC5589 in PDF, 298 KB, grouped with schematics in this index. The file name states only the part number.

Short 30.1 KB PDF for the 2SC5778 transistor, placed in the schematic category. Japanese JIS codes beginning with 2SC denote NPN bipolar devices, so the contents are…

Brief 41.9 KB PDF for the 2SC5453, in the JIS 2SC range that denotes NPN transistors. Catalogued as a schematic, it is most plausibly a short datasheet covering the…

Specification PDF, 30.2 KB, for the 2SC3913 transistor. JIS part numbering assigns the 2SC prefix to NPN bipolar devices, so the document is most likely a datasheet…

Compact 38 KB PDF named for the 2SC5380 transistor. The 2SC numbering marks an NPN device under the Japanese JIS scheme; the name gives no manufacturer or application.

Small 41.6 KB PDF dedicated to the 2SC3704, classified here as a schematic yet in practice a component reference.

Datasheet for the 2SC3613, a 241 KB PDF listed among schematic files although its content is a single-component specification.
