Here is a 151 KB PDF for the 2SD1230, filed under schematics although it relates to one transistor type.

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

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.

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…

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.

PDF of 60.0 KB named 2SC5127, categorized as a schematic though it should be the device datasheet for that NPN bipolar transistor.

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.

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

Compact 29.9 KB PDF for the 2SC5776, indexed as a schematic but named with a single semiconductor part number.

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…

The 2SC5567 transistor is the subject of this 49.6 KB PDF, which the catalogue lists as a schematic.

PDF of 472 KB describing the 2SC5085 component, an NPN transistor under the Japanese 2SC numbering scheme.

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

Reference PDF for the 2SC5489, 31.3 KB in size and filed as a schematic. In the Japanese JIS convention the 2SC prefix identifies an NPN transistor, so the document is…

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…

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.

The 2SC3916 NPN transistor is the subject of this 30.8 KB PDF. Since the name is only a JIS part number, where 2SC stands for an NPN bipolar device, it is best treated…

Part documentation for the 2SC3777, a 127 KB PDF whose name identifies a single NPN transistor under the JIS 2SC numbering.

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.
