I want to use stm8 mcu for electrical relay such as trip relay and must pass the esd and emc test . Which one is better to use for this subject ?

I thought stm8a should be better because it will be used in automotive systems , but after reading datasheet of stm8s003f3p6 and stm8af6223

It seems esd maximum rating of stm8s003f3p6 is better than stm8af6223 , so what is advantage of  stm8a  with respect to stm8s ?


Thanks a lot
