PDF file, 105 KB, for the 2SC4695 part. Since 2SC is the JIS designation for NPN bipolar transistors, the document is likely the component datasheet rather than a device schematic. Expect pinout, package outline, absolute maximum ratings and electrical characteristics. It serves when checking the transistor for shorts, identifying leads, or choosing a cross-reference substitute with adequate ratings. Make sure the marking and package on the installed part agree with the document.
