ESD issue

Hello Michiba-san,

At the moment direct comparative data between the ADuM7241
and the ADuM3201 is not available. I know that you are looking for a guaranteed
value however it seems like you or your customers are looking to improve system
level ESD ratings. Since there are so many variables that affect systems level
ESD it is difficult for us to provide data beyond component ESD testing done
during qualification. Slight modifications to the board layout or a change in
BOM can affect how a circuit would handle an ESD event so all we can say is
that our ESD Hardened parts will provided improved ability to handle ESD.

The only thing we can really guarantee is are things like the human body model
which generally is representative of how the part will handle ESD before and
during production while it might be handled by an operator. This however is not
any indicator of how well it will do with a system level ESD standard.

Regards,

Joe
