For the 2SK1905 N-channel field-effect transistor, this PDF of 92.7 KB is indexed under schematics, though a bare part number in the name points to a datasheet.

PDF for the 2SK1739A, 197 KB, listed as a schematic. The 2SK prefix follows the Japanese JIS designation for N-channel field-effect transistors, and the trailing A…

Covering the 2SJ589LS, this 33.2 KB PDF is catalogued as a schematic, though the name points to a component datasheet.

A 126 KB PDF dedicated to the 2SC5257, sorted into the schematic section although the name identifies a single component.

Part number 2SC4454 gives this 101 KB PDF its name, and the index places it in the schematic group.

Named only 2SC4213, this 289 KB PDF is catalogued as a schematic, yet the JEITA-style 2SC prefix identifies an NPN bipolar transistor, so a component datasheet is the…

PDF document for the 2SC5785, filed in the index as a schematic, though the part number follows the Japanese JIS scheme where the 2SC prefix marks an NPN bipolar…

Small 41.7 KB PDF for the 2SC5346; the _E suffix possibly marks an English edition, though the name alone cannot confirm this.

PDF documentation, 311 KB, for the 2SC3121 NPN bipolar transistor, named in the Japanese JIS 2SC style.

Catalogued under schematics, this 184 KB PDF carries only the part code 2SC3072 in its name and most likely contains that transistor's datasheet.

Filed as a schematic, this 52.9 KB PDF is named after the 2SB1668, a PNP bipolar transistor according to Japanese JIS numbering; the contents should therefore be its…

The 2SA1587 transistor is the subject of this 323 KB PDF, the largest in this group and likely to include detailed characteristic graphs.

PDF component reference, 101 KB, describing the 2SA1798 transistor, listed in the schematic section of the index.

Reference PDF of 96.5 KB tied to the 2N6237, a JEDEC-numbered discrete semiconductor; the index lists it as a schematic, but it most likely holds the device datasheet.

At 578 KB, this 2N3903 PDF is considerably heavier than a typical one-part sheet, which may mean scanned pages or an extract covering several related devices, though the…

Datasheet for the 2N3442 in a 136 KB PDF, filed in the schematic category. The r7 ending in the name likely marks a document revision number, though the name does not…

Indexed under schematics, this 181 KB PDF named 28512 most likely documents a 28-series 512 Kbit parallel EEPROM, though the name does not confirm the manufacturer or…
