DRV8432: Heat sink recommendation

Part Number:DRV8432

Hi,

I'm looking for a small heat sink for the DRV8432 operating at 2A-2.5A RMS.

optimal dimensions are: width - 3mm length - 4mm-5mm. height - 20mm-23mm.

any recommendations?

what is the Degrees/Watts spec needed for this type of load?

Thanks,

Shahar
