The 2SK3092 is described in this compact 31.3 KB PDF, catalogued as a schematic but acting as a datasheet. Under JEITA designations, a 2SK part is an N-channel FET.

A short 28.8 KB PDF for the 2SK2379, indexed as a schematic though it is almost certainly a component datasheet; JIS numbers starting with 2SK denote N-channel…

Titled 2SK2378, this 26.7 KB PDF is the smallest in its series and is listed under schematics, but the JIS part number indicates a datasheet for an N-channel FET.

The 2SK1420, an N-channel FET according to the Japanese JIS 2SK prefix, is the subject of this 103 KB PDF.

The largest of this group at 400 KB, this PDF is named for the 2SK241 and filed as a schematic.

The 2SJ349 P-channel FET is described in a 418 KB PDF, catalogued under schematics though it is a component datasheet.

Compact 27.2 KB PDF on the 2SC5291. The 2SC prefix identifies an NPN bipolar transistor in the JIS system, so this is most likely a short manufacturer datasheet, filed…

The 2SC4735 is covered by this 109 KB PDF, listed under schematics but named purely by part number.

The 2SC4685 is documented in this 186 KB PDF, filed as a schematic though the name is a transistor part number.

Here is the 106 KB datasheet-style PDF for 2SC4637, a JIS-numbered NPN bipolar transistor.

Filed as a schematic, the 124 KB PDF titled 2SC4555 names a discrete transistor, so its content is probably the datasheet.

Covering the 2SC4483, this 126 KB PDF is a semiconductor data sheet; the 2SC prefix follows JIS rules for NPN bipolar transistors.

Named after transistor 2SC4452, this 98.8 KB PDF is listed as a schematic but most likely contains the component datasheet.
