When reverse bias is enhanced the electric field at the junction also enhances. At some stage the electric field becomes so high that it breaks the covalent bonds building electron, hole pairs. Therefore a big number of carriers are created. This causes a large current to flow. This mechanism is known as Zener breakdown.
