IONI ESD protection

Questions
1

It’s me again… with a question.

I see on IONI specifications - Granite Devices Knowledge Wiki that there is some form of ESD protection, but what model (HBM, CDM…) and voltage level is it compliant to ?

My questions is for

  • the BiSS-C
  • the RS485
  • not for the GPIOs
  • maybe for the power supplies and the phases output, but I am less concerned.

Thanks.

Hi

IONI has these ESD diodes:
PESD3V3L5UY
ESD24VS2UE6327

Kind regards, Esa

Thanks. I can see D2, D3, D4, D5, D8, D11. On all abovementioned signals ?
PESD3V3L5UY are for 3.3 V signals, so what about those that can have higher voltages, like the RS485 or even the BiSS’ RS422 ?
