At the full 500 mA rating the saturation voltage climbs — budget 1.8–2.0 V typical — so the load supply must be at least 2 V above the load's minimum operating voltage to keep the Darlington in saturation. The 50 V Vce breakdown gives ample margin for a 24 V industrial bus or a 48 V automotive auxiliary rail.
