Part number 2SC5714 names this 166 KB PDF. Under the Japanese JIS scheme, 2SC parts are NPN bipolar transistors, so the document should list electrical ratings and a…

A 79.7 KB PDF for the 2SC3950 transistor, placed in the schematic category though the part-number name indicates a component datasheet.

English-edition datasheet, as the _E suffix commonly indicates, for the 2SC3941 NPN bipolar transistor, 50.9 KB PDF filed under schematics.

Largest of the _E series at 59.4 KB, the 2SC3936 PDF is catalogued as a schematic but is named like a transistor datasheet, with the suffix usually indicating an English…

Named solely 2SC4843, this 469 KB PDF belongs to the schematic section but almost certainly describes a single component: the Japanese JIS prefix 2SC identifies an NPN…

Transistor datasheet for the 2SC3774, presented as a 126 KB PDF and listed in the schematic category. Under Japanese JIS naming, 2SC denotes an NPN bipolar transistor.
