PDF datasheet material for the 2SD1194 transistor, about 138 KB, catalogued here under schematics.

PDF reference for the 2SD1160, about 220 KB, indexed as a schematic although the file name names only a transistor part.

A 90.4 KB PDF identified solely by the code 2SC4451. Under Japanese JIS semiconductor naming, the 2SC prefix marks an NPN transistor of the high-frequency type, so this…

A compact 42.3 KB PDF named after the 2SC5444 transistor. Under JIS numbering, 2SC denotes an NPN bipolar device intended mainly for high-frequency use, so this is…

Reference sheet for the 2SC4805 NPN transistor, stored as a compact PDF of about 40 KB with an _E suffix that probably indicates an English edition.

PDF reference, about 124 KB, for the 2SC3776 transistor. The JIS 2SC prefix identifies an NPN bipolar part, so although the file is labelled a schematic it most likely…
