Why does BrF3 have a hybridization of sp3d?

it is sp3d because BrF3 forms three bonds with flourine and has two lone pairs. This T- Shaped structure needs at least 5 orbitals to fit in the 10 electrons, so it uses a d orbital to accommodate it.

If you draw the Lewis structure, there should be 28 e- (21 from the 3 fluorine, 7 from bromine). The bromine is bonded to each of the 3 fluorine atoms by a single bond. That leaves 4 electrons which are put around the bromine atom as 2 lone pairs. This gives a total of 5 regions of electron density (3 single bonds + 2 lone pairs). A hybrid structure with 5 regions of electron density forms sp3d hybrid orbirals.
