Datasheet-type PDF of about 90.7 KB for the 2SC4413. No board, brand or revision appears in the name; the JIS 2SC prefix simply indicates an NPN bipolar transistor. A sheet like this is what a technician checks for pinout, case type and maximum collector voltage and current when diagnosing or substituting the part. It opens in any PDF viewer. Before trusting it, make sure the marking on the failed component genuinely corresponds to this number, since abbreviated SMD codes can be misleading.
