Datasheet link -Hi,
look at the datasheet. Usually it has some informations on that. Like an SOA diagram...
For more details I recommend to give link to a datasheet.
Junction temperature rise is the key of course.Or here do we have to limit the junction temeprature by limiting the total MOSFET losses.
This will tell us the max or short circuit current through MOSFET.
Realistic short ckt condition = 46A rms; 71A peak;Hi,
what´s your relaistice short circuit condition?
* max voltage
* turn off timing
* loop resistance
* do you have limited current?
Ok. Not using BLDC drive.Summary is that FETs and Sic FETs are generally no good for short circuit current....they generally cant turn off a short cct current...if you have shorts, then its IGBTs you need.
But if the s/c currnt is within the rating of your fet, then it would be ok.
Are you doing a HV BLDC drive?
