Second breakdown in SOA

Hiroshi

Hi Wolfspeed expert,

 

I have a customer using Wolfspeed’s 1200V discrete SiC MOSFET. They’re reviewing the datasheet and fond there’s no second breakdown region of SOA.

Could you please explain more detail why Wolfpseed’s SiC MOSFET does not have second break down region? What’s the difference between Si power devices?

 

Thank you for your support.
