Yes, it's all about typical vs worst case. I agree that worst case curves would be very useful.I see. The test condition for Vgs threshold is VDS = VGS.
How about figure 1? It tells me what current flows for a certain VDS and a certain Vgs.
At -4V VDS and -5V Vgs a current of 2A would flow (for the indicated pulse width). Or is that what you meant with "typical", i.e. it could very well be that the RdsON is much higher at this point and therefore the drain current lower...?
I understand that the RdsON at any Vgs voltage other than the specified is unknown.
Figure 1 should actually show worst case curves too, that would be useful.
