Specification PDF, 74.8 KB, for the 2SC3770 transistor. The 2SC code is the Japanese JIS designation for NPN bipolar transistors, so the content is component data, not a board schematic, despite the category. A technician would check collector-emitter voltage, collector current, dissipation and terminal order here before testing or replacing the part. When choosing an equivalent, match or exceed those ratings and the package style. Confirm the device marking on the PCB corresponds to this number.
