Indexed as a schematic, this 33.9 KB PDF for the 2SK655 is best read as a transistor datasheet, since 2SK numbers designate N-channel FETs under the Japanese JIS…

PDF of 42.8 KB for part 2SJ585LS, listed under schematics. JIS semiconductor coding assigns 2SJ to P-channel FETs, so this is most probably a datasheet with ratings…

Datasheet-style PDF named after the 2SJ342 and indexed as a schematic, 311 KB in size. The name itself identifies only the semiconductor type.

A 379 KB PDF covering the 2SJ304. The file name holds only the part number, with no reference to a product.

Brief 41.5 KB PDF on the 2SD1211 with an _E suffix, entered in the schematic category. Under JIS conventions the 2SD prefix stands for an NPN bipolar transistor for…

A 144 KB PDF whose name is just the part number 2SD1190, filed as a schematic but in practice a transistor datasheet.

Datasheet PDF of 42.5 KB for the 2SD1119, with an _E suffix following the number whose meaning the name does not give. The index files it as a schematic.

The 2SD1046 is documented in this 115 KB PDF, placed in the schematic group. Its name carries no detail other than the part number.

Covering the plain 2SC5261 without suffix, this 183 KB PDF is indexed as a schematic but concerns a single NPN bipolar transistor, as the JIS 2SC prefix indicates.

Indexed under schematics, the 116 KB PDF named 2SC5155 refers to a discrete semiconductor rather than a whole board.

Part reference for the 2SC4577, provided as a 106 KB PDF under the schematic type. With the JIS 2SC prefix denoting a high-frequency NPN bipolar transistor, the content…

Named simply 2SC4427, this 109 KB PDF documents a single semiconductor rather than a complete board.

PDF documentation for the 2SC4252, 302 KB, catalogued in the schematic section. No further information such as manufacturer, package or version is carried by the name.

PDF datasheet for the 2SC5587 transistor, 332 KB, filed under schematics. Only the part number is given; there is no manufacturer, package or version in the name.

PDF for the 2SC5584 transistor, only 45.9 KB, catalogued under schematics. The name holds nothing beyond the part number, so manufacturer and revision are not given.

The largest of this set at 474 KB, this PDF is named for the 2SC5097 and nothing more. The 2SC designation, under Japanese JEITA rules, belongs to NPN bipolar…

Datasheet-style PDF of 158 KB for the 2SC5765, indexed in the schematics section. Beyond the part number the name is uninformative; the 2SC prefix denotes an NPN…

The 2SC5810 NPN transistor is covered by this 177 KB PDF, indexed as a schematic though its content is most likely the datasheet.

Lowercase-named PDF of 51.5 KB for the 2SC5511, catalogued as a schematic but representing, under the JIS numbering system, an NPN bipolar transistor datasheet.

A compact 42.3 KB PDF named after the 2SC5444 transistor. Under JIS numbering, 2SC denotes an NPN bipolar device intended mainly for high-frequency use, so this is…

Component datasheet in PDF form, 87.9 KB, for the 2SC3899. The JIS numbering system uses 2SC for NPN bipolar transistors, which fits a part specification better than a…

Transistor number 2SC4824 is all the name of this 141 KB PDF reveals; the index places it among schematics.

Part number 2SC3449 names this 113 KB PDF, filed under the schematic type. In the Japanese semiconductor registry the 2SC prefix covers NPN bipolar transistors, so this…

Named 2SC5360, this 117 KB PDF concerns a Japanese JIS-registered NPN transistor, the 2SC prefix denoting a high-frequency type.

A 320 KB PDF named for the 2SC3329, listed under schematics though it is most probably a full transistor datasheet.

A 308 KB PDF named after the 2SC2753 semiconductor and placed in the schematic section.

Part-number document for the 2SC2236, stored as a 178 KB PDF under the schematic category.

English-language edition, judging by the _E suffix, of a document for the 2SB1488 transistor, stored as a 46 KB PDF under schematics but almost certainly a datasheet.

Transistor information for the 2SA1607, supplied as a 150 KB PDF and placed in the schematic category.

Part number 2SA1533 names this 51.3 KB PDF, with an unexplained _E suffix; despite the schematic category it is presumably the transistor datasheet.

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.
