CSD19538Q3A: To check whether 35V/0.42A/140mS is under SOA or not

Part Number: CSD19538Q3A

Hi Expert,

Pls help to advice whether 35V/0.42A/140mS is under CSD19538Q3A SOA or not.



  • Hello Eric,

    Thanks for the inquiry. A 25V/0.42A/140ms violates the SOA limits in the datasheet. The SOA current limitation for 35V/100ms is 0.3A. This corresponds to the DC limit line from the SOA curve in Figure 10 of the datasheet. We consider any pulse width >= 100ms to be DC. Please let me know if I can be of any further assistance.

    Best Regards,
