Steve,

I really don't know if this will help you since I am not familiar with the
ATF-55143, but I can't resist, so here goes :

For digital logic devices, ESD protection devices are not suppose to turn on
at the absolute maximum ratings of the device they're trying to protect.
They should turn on (start protecting) at some greater value.
The absolute maximum rating of a logic device is a DC value not an AC (ESD)
limit.
The question might be better phrased : Can your ATF-55143 survive an ESD
pulse of +/- 9V? This is the limit it would have to survive before the ESD
protection device kicks on. If this were digital logic the answer would be
easily "yes".

Dear Si'ers,
             I am using a ATF-55143 Single Voltage E-pHEMT Low Current Low 
Noise device in an RF front end application.  I need to make sure I am 
complient with contact ESD to +/-8KV.  The device has an absolute maximum 
rating of +1V to -5V.  Therefore the CM1213 I am using which is great as a 
very low capacitance ESD device, but of no use, since its break down voltage

is +/-9V.

Anybody got any ideas as to how to use the ATF-55143 device and ESD protect 
it without loading it with high capacitive ESD devices in my front end 
application.

Regards
