A 107 KB PDF titled with the lowercase part number 2sd1565, catalogued as a schematic yet almost certainly a transistor datasheet.

Covering the 2SK2952, this PDF of 414 KB is a discrete transistor document rather than a full circuit, as the JIS 2SK prefix indicates an N-channel field-effect…

A 413 KB PDF for the 2SK2699 transistor, filed as a schematic in this index. The 2SK prefix identifies it as a JIS-registered N-channel field-effect transistor, so the…

Reference sheet in PDF form (98.9 KB) for the 2SK1909 transistor, catalogued under schematics.

The largest of this group at 400 KB, this PDF is named for the 2SK241 and filed as a schematic.

A 32.3 KB PDF for the 2SJ591LS, filed under schematics but named like a transistor datasheet.

The name carries only the part number 2SD1195, so this 148 KB PDF is best treated as the datasheet for that transistor, even though the index labels it a schematic.

Filed under schematics, this 84.0 KB PDF carries only the part number 2SD1153 in its name and should be a transistor datasheet.

A 35.0 KB PDF relating to the 2SC5270. The 2SC prefix denotes an NPN bipolar transistor in the Japanese JIS system, so the document is most probably a compact datasheet…

The 2SC4685 is documented in this 186 KB PDF, filed as a schematic though the name is a transistor part number.

Transistor documentation for the 2SC4678 in a 220 KB PDF file, sorted into the schematic category.

PDF file of 129 KB titled with the part number 2SC5228, catalogued as a schematic but best treated as a transistor datasheet.

PDF reference, about 137 KB, for the 2SC4614 transistor. Although categorised as a schematic, a bare part-number name like this normally indicates a datasheet rather…

Datasheet-type PDF, about 236 KB, for the 2SC5176 transistor, catalogued as a schematic though the name contains only the part number.

2SC4579 datasheet candidate in PDF form, 102 KB, categorised as a schematic. The name follows the JIS convention in which 2SC denotes an NPN bipolar transistor for…

Filed as a schematic, the 124 KB PDF titled 2SC4555 names a discrete transistor, so its content is probably the datasheet.

The smaller 77.9 KB PDF here carries the type number 2SC4449, indexed as a schematic but almost certainly a component datasheet.

Reference PDF, 106 KB, for the transistor numbered 2SC4407. The 2SC prefix follows the Japanese JIS standard for NPN bipolar transistors, indicating datasheet content…

PDF of 51.8 KB for the 2SC5610 transistor, indexed with schematics although the bare part number suggests a manufacturer datasheet.

Filed among schematics, this 467 KB PDF carries just the transistor number 2SC4320 and should be regarded as its datasheet.

Listed under schematics, this 168 KB PDF is named after the 2SC5755 part number only. In JIS/JEITA terminology the 2SC prefix marks an NPN bipolar transistor for…

The 2SC5459 comes as a 186 KB PDF in the schematic category, though the part number, a JIS 2SC NPN transistor, points to a datasheet.

For the 2SC5450 there is a 41.0 KB PDF, filed as a schematic, most likely holding the datasheet of this NPN transistor from the Japanese 2SC family.

A 126 KB PDF documenting the 2SC3773 transistor, an NPN device under the JIS 2SC designation.

The 2SC3655 transistor is covered in this 91.8 KB PDF. Its 2SC prefix follows JIS numbering for NPN bipolar transistors, and the bare part-number name points to a…

PDF of 214 KB for the 2SC3328, an NPN bipolar transistor under the JIS naming system, catalogued here as a schematic though the content is likely a datasheet.

Part number 2SC2510 gives this 165 KB PDF its name. In JIS numbering the 2SC prefix belongs to NPN bipolar transistors, so the content is most likely the device…
