Part documentation for the 2SC5026 in PDF form, 41.3 KB, its name ending in an _E suffix. Filed as a schematic, though the JIS-style 2SC code indicates an NPN transistor, typically for high-frequency service, so the content is most likely a datasheet. Use it to check package outline, pin mapping and maximum voltage and current before replacing a damaged part. Any PDF viewer opens it. Confirm the marking printed on the component matches this part number, since many SMD transistors share similar codes.
