CAB650M17HM3 Gate Resistance

pj8761

Hello,

Is the CAB650M17HM3 rated to be operated with zero external gate resistance (assuming SOA limits arent breached)?

I'm asking as the datasheet switching energy losses for the module are specified using an external on/off resistance of 1.5 Ohms, whereas for the CAS380M17HM3 the datasheet switching energies are given for 0 external gate resistance. Figures 15 and 16 in the CAB650M17HM3 datasheet show switching energy losses down the 0 external gate resistance so if it is rated to work down to this resistance why is 1.5 Ohms used for the headline switching energy loss values?

Thanks
