Datasheet in PDF form for the 2SC4696, filed in the index under schematics although the name points to a discrete part document rather than a board diagram. Under the Japanese JIS naming system, the 2SC prefix marks an NPN bipolar transistor, usually one meant for high-frequency service. At 78.4 KB it is a short document. Use it to confirm pinout, package outline and maximum voltage and current ratings before fitting a replacement, and compare the body marking on the board part with the number shown here.
