Datasheet-style PDF of 118 KB for the 2SD1898, recorded in the index as a schematic but named after a single component.

Only 28.2 KB, this PDF named 2sk123 is catalogued as a schematic, but the name is a JIS transistor number, so a short datasheet is the likely content.

PDF of 426 KB named for the 2SK2842 part number and filed in the schematic category. Because the 2SK prefix denotes an N-channel field-effect transistor in JIS…

Filed as a schematic, this 412 KB document named 2SK2229 most likely contains the datasheet for that Japanese-numbered N-channel FET.

Part datasheet for the 2SK2033, provided as a 296 KB PDF and filed under the schematic category. The 2SK prefix follows the JIS standard for N-channel FETs.
