A 129 KB PDF labelled 2SC5562, kept in the schematic section of the catalogue. The name holds only the part number; the 2SC prefix in JIS/JEITA naming identifies an NPN bipolar transistor intended for high-frequency circuits, so the file is most likely its datasheet. Use it to check voltage, current and power limits, gain grouping and lead order when diagnosing a failed transistor or sourcing a substitute. Match the package drawing and marking with the original component on the PCB.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @cyberlanelectonik. Enginerys does not host this file.
