UCC12050: UCC12040 - Iso / surge / esd rating comparison

Part Number: UCC12050
Other Parts Discussed in Thread: UCC12040,

Hi,

I am wondering, why is it that the UCC12050 has improved Isolation and Surge rating over UCC12040, but the ESD rating is worse in the datasheet?

Shouldnt the ESD rating be better on UCC12050 than on UCC12040? What is the reason?

Regards

Kevin

  • Hi Kevin,

    Thanks for bringing this to our attention. The lower 1kV/500V (Human Body Model/Charge Device Model) you pointed out in the UCC12050 data sheet is actually a typo. Both UCC12040 and UCC12050 have the same ESD ratings that are correctly specified in the UCC12040 data sheet as 3kV/1kV. I apologize for that and we will get this corrected ASAP.

    Regards,
