ESDAxx Series
Dual transil array for ESD protection
P b
Lead(Pb)-Free
Description:
* The ESDAxx is a dual monolithic voltage suppressor designed to protect
components which are connected to data and transmission lines against ESD.
It clamps the voltage just above the logic level supply for positive transients,
and to a diode drop below ground for negative transients. It can also work as
bidirectionnal suppressor by connecting only pin1 and 2.
