Datasheet-style PDF of 101 KB for the 2SC4710, catalogued among schematics. The 2SC prefix is the Japanese JIS code for an NPN bipolar transistor, and the name adds no further details. A separate LS-suffixed variant of this number exists in the index, so confirm which version is on your board. Use the document to identify pins, read voltage, current and dissipation limits, and select a compatible substitute when the original transistor has failed short or open.
