The 2SK2740 transistor is the subject of this 143 KB PDF, filed as a schematic even though the name points to a component datasheet.

Reference sheet for the 2SK2739 in PDF format, 146 KB, indexed in the schematic section.

Indexed as a schematic, this 139 KB PDF actually concerns the 2SK2715, an N-channel field-effect transistor according to the Japanese JIS 2SK prefix.

A 110 KB PDF dedicated to the 2SK1922, which the JIS 2SK prefix identifies as an N-channel field-effect transistor.

Compact 31.8 KB PDF for the 2SK1868, filed as a schematic though named only by a part number.

Datasheet-type PDF for the 2SK1737, sized 90.0 KB and categorised as a schematic. The 2SK prefix comes from the Japanese JIS naming scheme for N-channel field-effect…

PDF document for the 2SK1530, filed under schematics although the name is only a semiconductor part number.

The 2SK1473 is the only information the file name gives, and that code follows the Japanese JIS scheme where 2SK means an N-channel FET.

A 117 KB PDF catalogued as a schematic but named after the 2SK1458 part number, so it most likely holds the manufacturer's data sheet for that semiconductor.

The 2SK1429 is covered by this compact 99.1 KB PDF, entered in the schematic category although a lone part number usually signals a datasheet.

PDF of 32.5 KB covering the 2SK656, a part from the JIS 2SK range of N-channel field-effect transistors, so it is effectively a component datasheet rather than a device…

At 151 KB, this 2SK543 PDF is one of the larger sheets in the series, probably including detailed characteristic curves and package dimensions.

Indexed as a schematic, this 411 KB PDF is named for the 2SJ516, and in Japanese semiconductor numbering 2SJ denotes a P-channel field-effect transistor.

Under the JIS semiconductor scheme the name 2SJ464 refers to a P-channel FET, and this 320 KB PDF, although indexed as a schematic, should be its datasheet.

Datasheet-style PDF for the 2SD1302, 46.0 KB, listed in the schematic category. The 2SD prefix follows the Japanese JIS designation for NPN bipolar transistors in…

Datasheet PDF for the 2SD1222, sized 183 KB and placed in the schematic section of the index.

The 2SD968 is covered by this 42.9 KB PDF, whose name includes an _E suffix with no explanation given.

Documentation for the base 2SC5265 part, a 112 KB PDF in the schematic category. Under JIS designations 2SC stands for an NPN bipolar transistor; a separate LS-suffixed…

At 464 KB, this PDF for the 2SC5264 is the largest of the related transistor files and is likely a full datasheet with characteristic curves.

Datasheet-type PDF of 220 KB for the 2SC5260, carried in the schematic section of the index.

The 2SC4688 transistor is documented in this 178 KB PDF, which the catalogue files under schematics.

A small 49.5 KB PDF for the 2SC4767 part, filed as a schematic; the trailing _E in the name is not explained, so check the document to see what it denotes.

PDF document for the 2SC4435, catalogued as a schematic but named after a discrete semiconductor part number rather than a board.

Component documentation for the 2SC4269 in PDF form, 108 KB in size, listed in the schematic category. Nothing beyond the part number appears in the name.

Filed in the schematic section, this 156 KB PDF is named for the 2SC4135, which by JIS convention is an NPN bipolar transistor, so expect a component datasheet inside.

The 2SC3987 document is an 83.4 KB PDF whose name contains only the part number, so expect a transistor datasheet rather than a device schematic, even though it is…

A 126 KB PDF for the 2SC4871, given with only the part number and filed in the schematic section.

Only the type number 2SC4836 appears in the name of this 110 KB PDF, indexed as a schematic.

Specifications for the 2SC3656 in PDF form, 90.4 KB. Parts beginning with 2SC in the JIS system are NPN bipolar transistors.

A 468 KB PDF covering the 2SC3607 transistor, filed in the schematic category but best treated as a manufacturer datasheet.

Datasheet in PDF form, 289 KB, for the 2SC3547B, filed with schematics. The B suffix marks a variant of the 2SC3547; the name alone does not say whether it denotes a…

Datasheet-style PDF named for the 2SC5322, 122 KB, though the catalogue labels it a schematic.

A 94.9 KB PDF for the 2SC3088, filed as a schematic but in practice probably a component datasheet. Its name contains just the part number.

A 147 KB PDF whose name is just 2SC2881, catalogued as a schematic. By JIS numbering this is an NPN bipolar transistor, and the file is most likely its datasheet rather…

PDF of 56.9 KB for the 2SC1688, marked with an _E suffix in the name and stored among schematics.

Here is a 122 KB PDF for the 2SA1696, a semiconductor numbered under the Japanese JIS system and listed among schematics, though a part-coded file like this is normally…

PDF for the 2SB1340 with a _1-2 suffix, 58.3 KB, filed among schematics yet describing a single transistor; the suffix may indicate a part or revision of the document…

A 30.8 KB PDF named for the 2SA1522, a part number in the Japanese 2SA series of PNP transistors.

PDF for the 2SA1512, 41.0 KB, with an _E suffix in the name whose meaning is not stated, possibly a document edition or language variant.

UTC version of the 2SB772 documentation, a 22.5 KB PDF; UTC very likely stands for Unisonic Technologies.
