Datasheet covering the 4N35 to 4N37 family of optocouplers, stored as a 276 KB PDF and catalogued as a schematic.

Component sheet for the 3LN01M, a 41.2 KB PDF filed in the schematic category. The name is only a part code; sibling files 3LN01N and 3LN01C share the base number, so…

Reference document for the 2SK2793, a 141 KB PDF catalogued under schematics. The 2SK designation in the Japanese JIS system denotes an N-channel field-effect…

A 418 KB PDF named for the 2SK2742, an N-channel field-effect transistor under the Japanese JIS 2SK prefix, placed in the schematic category.

A 137 KB PDF for the 2SK2714 with a 1-5 suffix that the name leaves unexplained, possibly an edition or page range.

Datasheet-style PDF for the 2SK2608, sized 413 KB and catalogued under schematics. Under the Japanese JIS naming system, 2SK denotes an N-channel field-effect…

The 2SK2350 is identified here only by its part number, in a 417 KB PDF catalogued as a schematic.

Datasheet-type PDF of 419 KB named after the 2SK2314. The 2SK prefix in the Japanese JIS designation identifies an N-channel field-effect transistor, so this…

Datasheet for the 2SK1923 in a 114 KB PDF, indexed as a schematic. Under JIS numbering the 2SK prefix denotes an N-channel FET, so the file describes one component…

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.

PDF reference for the 2SK583, a 57.1 KB file indexed as a schematic but in practice a transistor datasheet, since the 2SK prefix marks an N-channel field-effect…

Reference sheet for the 2SJ620 in PDF form, 345 KB, listed in the schematic category. The 2SJ prefix follows the Japanese JIS scheme for P-channel field-effect…

Here the only information in the name is 2SJ525, a Japanese-standard part code where 2SJ marks a P-channel field-effect transistor.

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.

Named 2SJ503, this 87.9 KB PDF is tagged as a schematic but most likely contains a transistor datasheet, because 2SJ is the Japanese JIS designation for P-channel…

The file, a 106 KB PDF placed in the schematic category, is identified only as 2SJ265. That number follows the JIS scheme for P-channel field-effect transistors, so it…
