I'm aware of this landing page.   Since there are so many  devices,  I'd like to know which part numbers specifically I need to  start with. Let me make it a bit more specific.. My customer would like to use 40V wide SOA parts  for current limiting application.

Hi,

what is the operating current that the device is passing? and how much temperature the device could go during operation, 

the first step would be for you is to filter out the results based on your expected Rdson, IDS, Vds, Vgs, Tj , package than after that left out mosfets we can compare and analyze which could give you the wider SOA.

The operating current could be about 50A. But my specific question would be - do you have any recommendation if  there is a family of 40V Automotive Mosfets which are targeted for  wide SOA applications? The filter will not be able to help me with sorting for SOA.
