Very small 26.9 KB PDF for the 2SK2951, likely a short datasheet or summary page given its size.

The 2SK1613 transistor is covered by this 36.4 KB PDF. In Japanese JIS/JEITA numbering the 2SK prefix denotes N-channel FETs, making this a component datasheet rather…

PDF file of about 148 KB describing the 2SJ315, listed in the schematic section. No board or brand is mentioned, only the part number.

Listed under schematics, this 110 KB PDF is named for the 2SD1347, an NPN bipolar transistor in the Japanese JIS 2SD series, and is probably its datasheet.

Compact 74.2 KB PDF titled 2sc5161 in lowercase, listed among schematics but almost certainly a single-part datasheet.

Listed under schematics, this 133 KB PDF named 2SC5108FT appears to be the datasheet for an FT-suffixed variant of the 2SC5108 transistor.

Sized at 316 KB, this PDF covers the 2SC5422, a part number in the Japanese JIS series used for NPN bipolar transistors.

English-edition datasheet, as the _E suffix commonly indicates, for the 2SC3941 NPN bipolar transistor, 50.9 KB PDF filed under schematics.

A 40.9 KB PDF titled 2SC3937 with the _E suffix often used for English versions of Japanese datasheets, listed here under schematics.

Reference sheet in PDF form, about 123 KB, for the 2SC5374 NPN transistor in the Japanese 2SC numbering series.

The only detail in the name is 2SC3450, which under JIS rules identifies an NPN bipolar transistor.

At 318 KB this PDF, identified only by 2SC3429, is the largest of the series and is listed under schematics.

Only the code 2SC5347 identifies this 115 KB PDF, so no model, board or revision is known.

The 2SC5317 transistor is the subject of this 122 KB PDF, which the index lists as a schematic though the name matches a datasheet.

Datasheet PDF, 170 KB, for the semiconductor numbered 2SC2705, placed in the schematic listing. Under JIS naming, the 2SC prefix marks an NPN transistor.

A 349 KB PDF named for the 2SC2670 transistor and catalogued as a schematic, most likely containing the device datasheet. JIS 2SC numbering identifies NPN bipolar parts.

Listed under schematics, this 52.8 KB PDF refers to the 2SB1675, a PNP transistor in the Japanese JIS numbering system, so its content should be the part datasheet.

English-language datasheet, going by the _E suffix, for the 2SB1440, stored as a 41 KB PDF and filed under schematics.

The 2SA1621 is covered by this 194 KB PDF, listed among schematics but really describing one discrete semiconductor.

Short 42.0 KB PDF describing the 2SB858 transistor, its name giving only the part number. Japanese JIS designations beginning 2SB denote low-frequency PNP transistors.

PDF for the 2SA2066 transistor at about 201 KB, catalogued with schematics but representing a component datasheet.

Compact 40.8 KB PDF for the 2SA1257, indexed as a schematic though its name carries only a part number.

Reference sheet for the 2N681 semiconductor, stored as a 209 KB PDF and listed in the schematic category, though a 2N designation points to a single-component datasheet.
