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.
