I'm sure that power MOSFETs do have some differences in construction, but that diode is in all MOSFETs; it's part of the way they're built. This diode is called a parasitic because it exists, but isn't there intentionally. Attached is a drawing of a MOSFET with the parasitic diode in red. Note that the diode only exists when the source and body are connected (as it usually is).
