A 144 KB PDF whose name is just the part number 2SD1190, filed as a schematic but in practice a transistor datasheet.

Covering the plain 2SC5261 without suffix, this 183 KB PDF is indexed as a schematic but concerns a single NPN bipolar transistor, as the JIS 2SC prefix indicates.

PDF reference of 143 KB named only for the 2SC4729. The 2SC prefix is the JIS code for an NPN bipolar transistor, so the catalogue label of schematic most likely stands…

Transistor 2SC4458 is the subject of this 103 KB PDF, which the catalogue lists as a schematic.

The 2SC4423 is described by this 102 KB PDF, which the index lists as a schematic. Since 2SC is the JIS prefix for NPN bipolar transistors, the contents should be a…

The largest of this set at 474 KB, this PDF is named for the 2SC5097 and nothing more. The 2SC designation, under Japanese JEITA rules, belongs to NPN bipolar…

106 KB PDF tied to the 2SC4204 transistor, with no other information in the file name. The JEITA 2SC prefix denotes an NPN bipolar device, so despite the schematic label…

For the 2SC5439 transistor, this 192 KB PDF is most likely a manufacturer datasheet, given that 2SC is the JIS designation for NPN bipolar parts.

A 467 KB PDF covering the 2SC5066, listed as a schematic but named after a JIS-designated NPN bipolar transistor, so expect a datasheet with ratings, curves and package…

PDF for the 2SC5417LS, 43.1 KB, catalogued as a schematic. The LS letters after the number mark a variant of the base 2SC5417, which has its own sheet; compare both…
