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.

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.

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

Identified solely as 2SJ257, this 96.0 KB PDF most likely documents a P-channel FET, the device class assigned the 2SJ prefix in the JIS system.

Component datasheet for the 2SD882S transistor as published by UTC (Unisonic Technologies), filed here under schematics although it is a part specification rather than a…

The 2SC5588 is covered by this 332 KB PDF document. Apart from the part number the name gives no detail, so maker and revision are unknown until the file is opened.

Filed as a schematic, this compact 79.7 KB PDF is named for the 2SC4169, a JIS-style designation that belongs to an NPN bipolar transistor, so the content is most…

A 98.4 KB PDF titled with the part number 2SC4162, filed under schematics but in practice expected to be the datasheet for that transistor.
