PDF of 101 KB for the 2SK1849 transistor, listed with schematics. In JIS numbering the 2SK prefix identifies an N-channel FET, so this should be the device datasheet…

Named solely for the 2SK1848, this 103 KB PDF is indexed as a schematic but is most likely a component datasheet.

Named after the JIS designation 2SK184, this 307 KB PDF is tagged as a schematic but is most likely the device datasheet.

PDF document for the 2SK1847, catalogued as a schematic but by its name most likely a component datasheet.

Reference PDF covering the 2SK1842, a part number in the JIS 2SK series used for N-channel field-effect transistors.

A 34.3 KB PDF for the 2SK1846 transistor. The 2SK prefix follows the Japanese JIS convention for N-channel FETs, so this is probably a part datasheet even though it is…

2SK1841 documentation in PDF form, 90.4 KB in size and listed as a schematic. The 2SK designation in the Japanese JIS system indicates an N-channel FET, so expect…

Datasheet-style PDF for the 2SK1840, sized 87.3 KB. Part numbers beginning with 2SK are registered under the Japanese JIS scheme for N-channel field-effect transistors.
