The 3N248 is covered by this 43.6 KB PDF, indexed under schematics but named only by its JEDEC part number.

Filed under schematics, though the file name is simply the JIS part number 2SD1903, so expect a component datasheet in this 131 KB PDF.

The 2SK3291 transistor is the subject of this 34.2 KB PDF, filed as a schematic although it works as a datasheet.

Part number 2SK2231 is the only information carried by this 420 KB PDF, which the index places among schematics but which most likely documents a single transistor.

Component documentation in a 114 KB PDF for the 2SK2011. Parts with the 2SK prefix are N-channel field-effect transistors under the Japanese numbering standard, so this…

For the 2SD1011, this 42.1 KB PDF carries an _E tag in the name with no stated meaning.

Datasheet for the 2SD662 NPN transistor, stored as a 44 KB PDF; the _E ending likely marks an English version of the document.

Variant documentation for the 2SC4738FT, a 138 KB PDF stored in the schematic category.

A 155 KB PDF bearing the part number 2SC4734 and nothing else. The 2SC prefix belongs to the JIS/JEITA system for NPN bipolar transistors, so despite the schematic label…

Here is a 144 KB PDF for the 2SC4728, filed as a schematic but carrying a discrete part number.

Documentation for the 2SC4781 in a 120 KB PDF, indexed as a schematic though the name matches a discrete semiconductor part.

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…

Part number 2SC4207 is the sole content of this 257 KB PDF's name, which the index places under schematics.

Compact 40.8 KB PDF for the 2SC536N, an NPN transistor under JIS numbering, where the trailing N is part of the stated part name.

PDF document, 124 KB, named for the 2SC5886 part, an NPN bipolar transistor by its 2SC prefix.

Short 30.1 KB PDF for the 2SC5778 transistor, placed in the schematic category. Japanese JIS codes beginning with 2SC denote NPN bipolar devices, so the contents are…

A PDF for the 2SC5464FT, 125 KB, indexed as a schematic. The FT suffix appears to denote a specific package or variant of the 2SC5464 NPN transistor, but the name does…

Brief 41.9 KB PDF for the 2SC5453, in the JIS 2SC range that denotes NPN transistors. Catalogued as a schematic, it is most plausibly a short datasheet covering the…

Filed as a schematic at 106 KB, this PDF bears only the identifier 2SC5070. That code belongs to the Japanese 2SC series of NPN transistors, so the document should be a…

Compact 38 KB PDF named for the 2SC5380 transistor. The 2SC numbering marks an NPN device under the Japanese JIS scheme; the name gives no manufacturer or application.

A 100 KB PDF reference for the 2SC4919 transistor, catalogued as a schematic. The 2SC prefix follows the JIS convention for NPN bipolar transistors; manufacturer and…
