Datasheet for the 2SC3965 NPN transistor, a 40.3 KB PDF listed as a schematic. The trailing _E in the name commonly marks an English-language edition of a Japanese maker's sheet, though the name itself does not confirm this. JIS 2SC numbers identify NPN bipolar parts, and the document should give ratings, pin order and outline dimensions. Use it when checking a suspected failed transistor or sourcing an equivalent, and compare the marking C3965 and package on the board first.
