there is no dedicated "catch" diode. I think you mean the body diode. The diodes are a side effect when producing MOSFETs.
But they are slow (high reverse recovery time). So for fast switching with low dead time I recommend to use external diodes.
For slow switching there is no need for external diodes.
For a more detailed answer we need more details of your circuit.
