We try to calculate/get the Rds(on) value from the SOA of the D/S. However, we don't get the exact Rds(on) value from SOA curve and to match EC table.
For example, When the IDS is 400A and VDS is 0.4V, the Rds(on) should be 1mR. But in the EC table, the max. Rds(on) is 0.59 @10Vgs. is this correct?
1. How do you usually define the Rds(on) value in the EC table?
2. How do you draw the Rds(on) limitation on the SOA curve?
