Good Day,
I want to compare Safe operating area of two MOSFETs based on graph given by manufacturer in datasheet. Since our application is 24V Inverter so what i concluded based on below information is that device A can handle higher current for DC operation, 10ms operation and 1ms operation and values of current at 24V for these three operating points are 10A, 20A and 100A as compared to 0.22A, 1A and 17A of device B, However for 100us operating point device B has higher current carrying capability as compare to device A and value is 287A as compare to 260A for device A for 24V. Now my question is that is my analysis is correct and what else you can identify from this information when comparing two MOSFETs. Secondly, since I am switching at 20kHZ for my application so I want to see the behaviour at operating point of 50us which is not given in this graph. Can anyone please help me in identifying the difference at 50us operating point. Thank you
