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…

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

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…

Compact 33.5 KB PDF for the 2SC3664 transistor. The 2SC prefix, under the JIS scheme, signals an NPN bipolar device; nothing else is stated in the name.

Larger than its neighbours at 256 KB, this PDF is named only 2SC3437 and filed as a schematic.

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…

Indexed as a schematic, this 199 KB PDF actually carries only the part number 2SC1959, pointing to a single NPN bipolar transistor under the JIS naming scheme.

Data document for the 2SB1556 bipolar transistor, 177 KB in PDF, filed under schematics.
