This 244 KB PDF covers the 2SD2075A; the trailing A marks a variant of the base 2SD2075 type, though the name does not say how it differs.

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

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.

The 2SC5226 is covered by a 112 KB PDF that the index classes as a schematic, though the name indicates a component datasheet.

A 152 KB PDF titled with the device number 2SC4443 and grouped among schematics. In the JIS scheme, codes starting with 2SC refer to NPN transistors for high-frequency…

For the 2SC5439 transistor, this 192 KB PDF is most likely a manufacturer datasheet, given that 2SC is the JIS designation for NPN bipolar parts.

Named after the 2SA1527 transistor, this 30.7 KB PDF appears in the schematic category though its content should be the datasheet for the part.

Datasheet-type PDF for the 2SA1357, sized at 177 KB and catalogued as a schematic. The file name gives only the part number.

For the transistor 2SA2039 this 40.2 KB PDF most likely provides the manufacturer datasheet, even though it sits in the schematic category.

Datasheet PDF of 190 KB for the 2SA1761, filed under the schematic type. In the JIS scheme the 2SA prefix denotes a PNP bipolar transistor, and the name gives nothing…

Datasheet for the 2N3392 in a 296 KB PDF, filed as a schematic. Identical in size to neighbouring 2N3390 to 2N3393 entries, it is probably a shared family document…

Datasheet for the 1T412 transistor, 59.8 KB in PDF format and stored with schematics. The 1T prefix places it among Soviet germanium transistors.

Laptop schematic for the Lenovo E47, built on a Quanta board with the project code KL9A, packed in a 1003 KB RAR archive.

PDF covering the 3SK189, about 178 KB in size and listed in the schematic category, though the name points to a single component datasheet.

PDF of 43.6 KB for the 3N252, listed under schematics though the name is a bare JEDEC part number.

A compact 106 KB PDF covering the 2SK2919 transistor, indexed as a schematic though the name points to a manufacturer datasheet.

The 2SC3922 is the subject of this short 30.5 KB PDF, listed as a schematic with no suffix or revision in its name.

Named after the JIS part number 2SC2816, this 50 KB PDF appears in the schematic category but most likely contains the datasheet of an NPN bipolar transistor, as the 2SC…

A 46.1 KB PDF datasheet covering the 2N3019 transistor, indexed in the schematic category.
