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.

A 247 KB PDF titled only with the part number 2SC4667, catalogued here as a schematic. The 2SC prefix is the JIS code for an NPN transistor intended for high-frequency…

The 123 KB PDF bears the part number 2SC4644 and nothing else. That makes it a reference for a single NPN transistor rather than a full circuit diagram, despite the…

Here is the 2SC5242 documentation as a 173 KB PDF, placed in the schematic category but evidently a part datasheet going by its name.

The 2SC5238 is covered by this 105 KB PDF, filed among schematics but named like a discrete-component datasheet.

Component document for the 2SC5201 part number, catalogued as a schematic but almost certainly a semiconductor datasheet given the name and small 115 KB PDF size.

Small 56 KB PDF covering the 2SC4626 part, with an _E suffix that possibly marks an English-language version of the original document.

PDF of about 63 KB for part 2SC4618, with a trailing h in the name whose meaning is not stated and may denote a variant or document version.

Small 39.3 KB PDF covering the 2SC4562, with an unexplained _E suffix in the name, listed under schematics.

Filed under schematics, this 244 KB PDF is named after the part number 2SC4479, which follows the Japanese JIS scheme where the 2SC prefix marks an NPN bipolar…

Listed as a schematic, this 103 KB PDF is titled with the device code 2SC4461. In the JIS semiconductor naming scheme, 2SC stands for an NPN bipolar transistor meant for…

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

Small 24.5 KB PDF labelled 2SC4412, catalogued as a schematic. In Japanese JIS designations 2SC marks an NPN bipolar transistor, and the compact size suggests a brief…

Part datasheet for the 2SC5589 in PDF, 298 KB, grouped with schematics in this index. The file name states only the part number.

Reference PDF for the 2SC4224, at 97.3 KB, catalogued as a schematic although the name is just a semiconductor part number.

A 126 KB PDF for the 2SC5096FT, which adds an FT suffix to the base type 2SC5096. Under JEITA naming the 2SC prefix denotes an NPN bipolar transistor, and suffixes like…

PDF reference of 290 KB for the 2SC4215, indexed as a schematic but named only by part number.

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.

A 108 KB PDF titled 2SC4110, catalogued under schematics although the name is simply a semiconductor part number.

A 50.2 KB PDF for the 2SC5566, sitting in the schematic section of the index. The name is a bare part number; the 2SC designation in Japanese semiconductor naming refers…

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.

A 29.5 KB PDF referencing the 2SC5792 transistor, an NPN device in the JIS-registered 2SC range.

PDF of 31.1 KB on the 2SC5791, an NPN bipolar transistor according to its Japanese 2SC prefix.

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…

2SC5720 component documentation in PDF form, 156 KB, indexed as a schematic. The 2SC prefix in Japanese semiconductor numbering identifies an NPN transistor of the…

PDF of 208 KB covering the 2SC5550, listed in the index under schematics but by its JIS part code an NPN bipolar transistor, so treat it as a component datasheet.

The 2SC5488 is covered by this 34.5 KB PDF, indexed as a schematic. Since 2SC numbers designate NPN bipolar transistors in the Japanese JIS system, the file is likely a…

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…

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…

The 119 KB PDF titled 2SC5052 sits in the schematic category, though its name is a JIS part number for an NPN bipolar transistor and the content is most likely a…

Component reference for the 2SC3963, supplied as a 193 KB PDF in the schematic category.

A 39.2 KB PDF for the 2SC3956 transistor, indexed as a schematic but by its name a datasheet for a JIS-designated NPN bipolar device.

Datasheet PDF for the base 2SC5417, 45.9 KB, filed in the schematic section; a separate LS-suffixed variant exists in the same set.
