Is a diode required for feeding the VDDD pin from a 5V LDO? There are a few configurations shown in the documentation. The ones where VDDD is externally sourced appear to have Diodes. The CYPD3171 dev kit has a 30V 5A diode. I am hoping that is overkill or, is there something structural in the part that can back feed the VBUS to the VDDD pin? I can’t imagine I would ever need a 5A (Huge package size) diode to feed VDDD so I am looking for some confirmation here.

The CCG3PA current consumption specification is about 10mA @5V . There is not mandatory of selecting the diode's forward current with 5A.
