PDF of 173 KB for the 2SC4707, sorted into the schematic category. Because 2SC is the JIS/JEITA designation for NPN bipolar transistors, expect a component datasheet giving maximum ratings, hFE classes, characteristic graphs and outline dimensions. The filename states only the part number. Consult it before desoldering to confirm pin order, and when sourcing a substitute make sure voltage, current, power and frequency specifications are equal or higher than those listed.
