Small 37.9 KB PDF for the 2SC4715, with an _E suffix in the name whose meaning is not stated, possibly a language or document edition marker.

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.

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

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.

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.

PDF reference for transistor part 2SC4428, 107 KB, indexed under the schematic category.

A 105 KB PDF covering the 2SC4426, filed as a schematic although the name is a component number.

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…

PDF of about 113 KB identified by the transistor number 2SC4403. The JIS prefix 2SC marks an NPN bipolar transistor, so this document should provide datasheet…

Only the part number 2SC5108 appears in the name of this 242 KB PDF, which is filed as a schematic but should be read as a transistor datasheet.

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

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.

Part-number PDF for the 2SC4107, 93.2 KB, stored in the schematic category. Nothing in the name points to a specific device or board; the 2SC prefix marks an NPN bipolar…

A 31.3 KB PDF for the 2SC5764, stored with the schematics. The name contains just the semiconductor part number; in Japanese numbering, 2SC identifies an NPN transistor…

Named 2SC5569 and weighing 50.3 KB, this PDF sits in the schematic category but refers only to a transistor 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…

A 129 KB PDF labelled 2SC5562, kept in the schematic section of the catalogue. The name holds only the part number; the 2SC prefix in JIS/JEITA naming identifies an NPN…

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 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…
