PDF reference, about 124 KB, for the 2SC3776 transistor. The JIS 2SC prefix identifies an NPN bipolar part, so although the file is labelled a schematic it most likely contains datasheet specifications. It can be opened in any PDF reader and used to confirm base, collector and emitter positions, maximum voltage and current, and package dimensions. That information helps when testing junctions with a diode-mode meter or selecting a replacement. Compare the marking on the actual component before ordering.
