A small 49.5 KB PDF for the 2SC4767 part, filed as a schematic; the trailing _E in the name is not explained, so check the document to see what it denotes. Under JIS numbering, 2SC indicates an NPN bipolar transistor for high-frequency use, making this a component datasheet in all likelihood. Use it to confirm pin assignment and package, look up maximum ratings, and evaluate replacements. Match the printed marking code on the actual part before relying on the stated pinout.
