Variant documentation for the 2SC4738FT, a 138 KB PDF stored in the schematic category. Under JIS numbering 2SC identifies an NPN bipolar transistor, and the FT suffix marks a version of the 2SC4738, likely a different package, though the name does not define it. Plain and F-suffixed versions of this number are also catalogued, so match the complete marking on the board. Compare the outline drawing with the footprint and use the ratings listed to verify that any replacement is suitable.
