MMBT3904TT1G - Footprint:
Package_TO_SOT_SMD:SOT-416 - 3D model: SOT-416, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.8 mm nominal SOT-523 height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
