PDF sheet of 38.4 KB for the 2SD2575, with an _E suffix in the file name. Filed as a schematic, it most likely holds datasheet content, because 2SD is the JIS code for…

Datasheet for the 5HP01N part in PDF form, about 27 KB. No device or motherboard is named; the code with an N ending appears to be a package variant of the 5HP01 series.

Combined datasheet PDF of 210 KB covering the 4N25 to 4N28 and 4N35 to 4N37 optocouplers, although indexed as a schematic.

PDF of about 25.4 KB for the 3SK303 semiconductor, filed in the schematic category. The file name holds only the part number.

A 41.8 KB PDF named for the 2SD2457 with an E tag, filed as a schematic. By the JIS scheme, 2SD marks an NPN bipolar transistor, so expect a component reference rather…

This 91.1 KB PDF covers the 2SD1887 transistor; it sits in the schematic category but the file name matches a JIS component designation, pointing to a datasheet.

Datasheet PDF for the 2SK2889, 417 KB in size and indexed here under schematics. The name states nothing beyond the part number.

PDF of 426 KB named for the 2SK2842 part number and filed in the schematic category. Because the 2SK prefix denotes an N-channel field-effect transistor in JIS…

The smallest of this group at 23.0 KB, this PDF covers the 2sk2474, a JIS-numbered N-channel FET.

A 134 KB PDF for the 2SK2460N, catalogued as a schematic but almost certainly a datasheet for a discrete transistor, since 2SK numbers under the Japanese JIS system…

Filed as a schematic, this 412 KB document named 2SK2229 most likely contains the datasheet for that Japanese-numbered N-channel FET.

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…

Part number 2SK1906 is all the name reveals about this 96.0 KB PDF, which sits in the schematic category.

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

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.

Part reference for the 2SK1452 in PDF form, 111 KB, classified as a schematic. The name states only the device number.

A 109 KB PDF for the 2SK1446, catalogued as a schematic and probably the main data sheet for this transistor.

The 2SK1412 is a Japanese-registered N-channel MOSFET, and this 110 KB PDF is its reference document, catalogued as a schematic.

Part reference sheet in PDF form for the 2SK663, carrying a 2SK prefix that under the Japanese JIS system denotes an N-channel FET.

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…

Covering the 2SK443, this 95.2 KB PDF sits under schematics, though the JIS 2SK naming for N-channel field-effect transistors indicates a component datasheet.

Part number 2SJ596 is the only information in the name of this 29.9 KB PDF, which is filed as a schematic.

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

The 2SJ382 P-channel FET is described in this 96.9 KB PDF, filed as a schematic though it is a component datasheet.

Reference sheet for the 2SJ345 in PDF format, about 333 KB. The name gives only the part number, with no board or device information.

A compact 27.8 KB PDF named after 2SJ164, a JIS designation identifying a P-channel FET.

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…

Compact 44.8 KB PDF for the 2SD1051, with an _E suffix in the name whose meaning is not stated, possibly a language or edition marker.

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

A 206 KB PDF named only 2SC5148, filed with schematics but describing a single part. In the Japanese JIS system the 2SC prefix denotes an NPN bipolar transistor, so the…

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.

PDF part sheet for the 2SC5577, 40.7 KB, catalogued with schematics. The name gives only the part number and says nothing about the maker or revision.
