Dear @gwentech ,

Good day!!

 

Yes it can withstand 12KA pulses. The surge current limit for the module is 35KA @ Tvj max calculated at 10ms. Here you are requesting 8ms pulse, so the energy is lower. which means the surge current capability rises to about 37.5 KA for 8ms.

Note: I am talking only about pulsing.

You need to use the appropriate cooling system.

 

Best Regards,

Anil Kumar.
