ESDALC6V1P6

5/10

®

The measurements done here after show very clearly (figure A5) the high efficiency of the ESD protection:

figure A5b).

One can note that the ESDALC6V1P6 is not only acting for positive ESD surges but, also, for negative

ones. For this kind of disturbances, it clamps close to ground voltage as shown in figure A5b.
