Hi forum.

where can I get Power MOSFET reliability data from Infinion?

The results I am getting from MIL217 prediction are rather poor and I think actual reliability may be better.

Hello @paulb ,

Thank you for posting on Infineon Developer community. 

Product reliability data or the FIT report is already available for download for a few devices and can be found under "FIT Report" tab on the respective product page under "Documents" section.

If it is not available for any device, you may request the same through below link.

Please feel free to reach out to us in case you have further questions related to this topic.

Thanks for help Meghanna, I had not noticed it.

It states that the ambient temperature is 55C with no mention of dissipation. The JEDEC standard it refers to does not give precise details about how a manufacturer should present this data.I assume that the data is for minimal dissipation so that TJ  equals ambient temp. is that correct ?

Also, do Infinion publish models that would give activation energy for other stressors beyond temperature?

Possibly there are other stressors I should be accounting for.

The MTTF I am getting from the infinion data is about 1000 times better than MIL217 Vita51 for 100 deg C Jn temp. It is a bit difficult to justify this.

My mistake, taking all pi factors into account infinion data for my device is very close to mil217/ vita51
