Power Cycling Capability curves (Nf vs ΔT) for discrete SiC MOSFETs in TO-247 packages

[blaze22]

Hello everyone,

I am currently working on a lifetime estimation for a SiC-based power converter design. I am specifically looking for Power Cycling Capability data for discrete SiC MOSFETs in TO-247 packages.

While power modules (like HybridPACK or EasyPACK) usually have well-documented Nf curves in their application notes, finding similar "to-failure" data for discrete SiC components is proving to be difficult.

I am looking for an analytical lifetime model for discrete SiC devices, ideally using the CIP2008 formula or a similar approach with clearly defined parameters.

Any insights, documentation, or links to technical papers would be greatly appreciated,

Best regards
