Other Parts Discussed in Thread: CSD18533Q5A,
In the datasheet for the CDS18531Q5A and many of the other TI MOSFETs, the conditions for the maximum SOA graph are stated as single pulse, Rtheta J-C = 1.0 C/W. For what Rtheta C-A is this graph valid?
Is it the minimum (125C/W) or 1sq in of 2 oz copper (50C/W) or something else?
I am trying to select an N-ch FET for an overcurrent protection circuit that clamps the current by modulating the gate for a delay period before turning off the FET. I am looking for a FET that can handle 4A at 20V Vd-s for at least 10mS. Is there a way to know what will work without opening every datasheet?
