The 2SD2179 transistor is the subject of this 43.9 KB PDF, carrying an _E suffix in its name.

The 5LP02N is covered by this 42.2 KB PDF, catalogued as a schematic but most likely a component datasheet.

Document for the 2SD1624, a PDF of 144 KB stored in the schematic section; with only a part number in the name it should be treated as a datasheet.

Small PDF of 27.3 KB for the 3LN01N, catalogued as a schematic though the name reads as a discrete transistor part number, so it is most likely a datasheet.

Indexed as a schematic, this PDF is named 2SD1459, a Japanese JIS designation that points to a datasheet for an NPN transistor rather than a board diagram.

Filed under schematics, this 74.1 KB PDF is named after the 2SD1953, which in Japanese JIS numbering is an NPN transistor for low-frequency applications.

A compact 36.0 KB PDF for the 2SD1949 transistor. The 2SD prefix in the JIS system designates an NPN device for low-frequency circuits, so the content is expected to be…

Datasheet-style PDF of 83.8 KB named for the 2SD1940, an NPN transistor under Japanese JIS numbering, in which 2SD stands for NPN low-frequency types.

A 133 KB PDF for the 2SD1935, a transistor in the Japanese 2SD family, which the JIS standard reserves for NPN low-frequency devices.

Named 2SD1934 with an _E suffix, this 40.2 KB PDF is most likely the datasheet for that NPN transistor, since 2SD is the JIS prefix for NPN low-frequency types.

At only 34.4 KB, this PDF is a short reference for the 2SD1913 transistor. Under Japanese JIS part numbering the 2SD prefix identifies an NPN device for low-frequency…

The 42.4 KB PDF is named for the 2SD2345 and carries an _E suffix, whose meaning the name does not explain.

Catalogued as a schematic, this 156 KB PDF is named after the 2SD1906, a Japanese JIS part number, so it is most likely the component datasheet for that transistor…

A 136 KB PDF for the 2SK2887, with a 1-5 suffix in the name that most likely refers to page range or a document section, though this is not certain.

Second copy of documentation for the 2SK2887, a 139 KB PDF listed under schematics, with the part number written in lower case and no other information in the name.

A small 40.3 KB PDF for the 2SK2867, filed as a schematic; the modest size suggests a short datasheet or summary page. The name contains nothing but the part number.

PDF datasheet, 411 KB, for the 2SK2847, placed in the schematic category of the index. Only the part number is given in the name, with no maker or revision.

PDF for the 2SK2299N, 137 KB, carrying an extra _1-5 suffix in the name whose meaning is not stated; it may mark an alternate edition or page range.

Catalogued as a schematic, this 86 KB PDF is named only after the part number 2SK2273, so it is almost certainly a component datasheet, not a board diagram.

Datasheet-style PDF, 379 KB, for the 2SK1486 N-channel FET, going by the Japanese 2SK type prefix in the file name.

Component documentation for the 2SK1475, a JIS-style part number whose 2SK prefix identifies an N-channel FET.
