Datasheet-sized PDF of 38.0 KB for the 2SC5474, with an _E suffix in the name that likely marks an English edition; that reading is an inference. The part number follows the Japanese 2SC scheme for NPN bipolar transistors, even though the file is catalogued as a schematic. Expect pinout, package drawing and maximum ratings. Use it to verify a replacement, confirm the marking on the body and observe the electrical limits. Compare it with the neighbouring 2SC5472 and 2SC5473 sheets when hunting for an equivalent.
