A 93.3 KB PDF data sheet for the 2SC4520, a JIS-coded part where the 2SC prefix means NPN bipolar transistor. Nothing beyond the part number appears in the name, so maker and package are not known from the listing. Open it in any PDF viewer to check voltage and current limits, hFE grouping and the pin diagram. Before replacing a failed transistor, verify the body marking on the board and compare ratings of any substitute, keeping the same or higher limits.
