    MOSFET - Datasheet help


    A N-Channel Mosfet when in the on-state and no drain/load current flowing, the Vds voltage would be zero (i.e differential voltage across drain and source). At this point, when a load connected to mosfet's source is switched on by an external switch would draw a 50A of DC current. How to interpret the SOA curve
    at these conditions when drain/load current begins to flow and Vds (voltage Vds = 0V, i.e 48V on either side as an example)

    Example mosfet:

    Can any one help me explaining how to interpret the SOA curve?

    Thanks for the help.
