Coss eff. is a fixed capacitance that gives the same charging time as Coss while VDS is rising from 0 to 80% VDSS . Calculated continuous current based on maximum allowable junction temperature. Package limitation current is 75A. Limited by TJmax , see Fig.12a, 12b, 15, 16 for typical repetitive avalanche performance. |
