Compact 42.5 KB PDF for the 2SD1824, carrying an E suffix in the name that is not otherwise explained.

Component data for the 2SD2130 NPN transistor, a PDF of about 209 KB. The name carries no board or device information; it is a part sheet following the Japanese 2SD…

Datasheet for the 2SD2117, filed as a schematic but actually a component specification in PDF form, about 67.5 KB.

Indexed as a schematic, the 2SD1723 PDF of 146 KB is a component sheet for one discrete transistor.

This 145 KB PDF carries the 2SD1722 part number and nothing more, so it is best treated as that transistor's datasheet.

Datasheet-style document, 133 KB in PDF format, covering the 2SD1681 part number and listed as a schematic.

Covering the 2SD2067, this 60 KB PDF carries an E suffix that the name leaves unexplained.

Larger 185 KB PDF for the 2SD2012, written in lowercase in the name and placed among schematics.

Part datasheet, most likely, for the 2SK2837, provided as a 426 KB PDF and indexed as a schematic.

Reference document for the 2SK2679, a 393 KB PDF in the schematic category. The 2SK prefix is the Japanese JIS registration for N-channel field-effect transistors, so…

Small 23.4 KB PDF for the 2SK2660 transistor. The 2SK designation comes from the Japanese JIS system for N-channel FETs, so the file is most likely a brief datasheet…

PDF of 312 KB for the 2SK2645. The trailing 01mr token is not decoded and may be the manufacturer's internal document code or edition.

A 30.5 KB PDF for the 2SK2631, filed among schematics though the number is a JIS N-channel FET designation, meaning the content is a component datasheet.

Part documentation for the 2SK2628LS, a 28.6 KB PDF. The 2SK prefix places it in the Japanese JIS family of N-channel field-effect transistors, and the LS suffix denotes…

Component sheet for the 2SK2614, delivered as a 172 KB PDF. Within JIS numbering, 2SK marks an N-channel field-effect transistor, so the document presents ratings…

The 2SK2445 gives its name to this 410 KB PDF, categorised as a schematic yet most likely a datasheet, because 2SK codes in the JIS scheme identify N-channel FETs.

Short PDF of about 34 KB tied to the 2SK2128 part number. It is catalogued as a schematic, but with nothing besides the part number in the name it is presumably a…

The 2SK2101 part number is followed by an extra 01mr suffix in this 175 KB PDF. The name does not explain that suffix, which could be a document code or revision.

Largest of this group at 382 KB, this PDF documents the 2SK1930, an N-channel field-effect transistor under Japanese JIS numbering.

Only the part number 2SK1897 identifies this 97.1 KB PDF, which the index places among schematics.

PDF reference, 105 KB, for the 2SK1813 transistor. In the Japanese JIS scheme, 2SK designates an N-channel field-effect transistor, so this is probably its datasheet.
