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…

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 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.

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.

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.

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 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…

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.

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

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.

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…

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…

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 of 125 KB for the 2SC4854, placed under schematics in the index. Only the part number is given in the name.

At 320 KB, the largest document in this group, this PDF is for the 2SC3862 transistor. The 2SC prefix follows the JIS scheme for NPN bipolar devices, so the content is…

Specification document for the 2SC4782 transistor, saved as a 46.9 KB PDF whose _E ending likely marks an English version.

A 99.4 KB PDF for the 2SC3779 transistor. The file name gives only the part number; the 2SC prefix follows the Japanese JIS scheme for NPN transistors, so this is almost…

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…

The 2SC4909 NPN transistor is documented in this 61 KB PDF, listed under schematics but by its name a component datasheet.

Small 41.6 KB PDF dedicated to the 2SC3704, classified here as a schematic yet in practice a component reference.

PDF document of 212 KB for the 2SC3620, filed under schematics but in practice a component datasheet for a discrete transistor.

Specification document for the 2SC3515 transistor, a 225 KB PDF placed in the schematic category.

Catalogued as a schematic, this 127 KB PDF carries only the designation 2SC3466 in its name.

Filed under schematics, this 209 KB PDF is named after the part number 2SC3405, which follows the Japanese JIS scheme where the 2SC prefix marks an NPN bipolar…

The 140 KB PDF is identified only by the transistor number 2SC3393 and contains no board or model reference.

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

Reference sheet for the 2SC5324, supplied as a 124 KB PDF and catalogued under schematics, though the name suggests a single-component datasheet.

Compact PDF of 48.2 KB named after the 2SC3315 part number, catalogued as a schematic but most likely a datasheet for that discrete transistor.

Covering the 2SC3150 transistor, this 103 KB PDF sits in the schematic category of the index.
