Do BJT (Darlington) transistors have a minimum collector current?

I am using a TIP122 Darlington transistor. From the graph provided in the datasheet, I can see that the saturation voltage decreases as the collector current decreases.

Since the load I am driving upstream only draws 400mA, can I assume that the aforementioned trend continues? That is, at Ic of 400mA, the saturation Vce voltage will decrease to below 1V?

Or do transistors have a minimum Ic threshold that disrupts this trend? I can't seem to find such a rating on the datasheet.

• And now, as I try to figure out whether I know enough to answer this, I'm realizing I don't know the actual reason saturation voltage is a thing. Something to look up, I suppose. I imagine some (most? all?) of this variation with collector current is due to parasitic resistances, though. Feb 4 '19 at 13:40
