Relevant constraints and selected phenomenological implications of a class of two Higgs doublet models where flavour-changing neutral currents (FCNC) couplings are suppressed by small entries of the mixing matrix are analysed. This property of the considered models is the result of a discrete symmetry of the Lagrangian such that the FCNC are completely fixed, in the quark sector, by the CKM mixing matrix V and the ratio of the vacuum expectation values of the neutral Higgs. Extending it to the leptonic sector introduces FCNC controlled by the PMNS mixing matrix. The analysis involves a significant number of processes which include tree and loop level transitions mediated by a charged and/or neutral Higgses. The new physical scalars, i.e. beyond the standard Higgs boson, can have masses within experimental reach.
