Application Information
See also California Micro Devices Application note AP209, Design Considerations for ESD protection.
In order to realize the maximum protection against ESD pulses, care must be taken in the PCB layout to minimize
parasitic series inductances to the Supply and Ground rails. Refer to Figure 1, which illustrates the case of a positive
ESD pulse applied between an input channel and Chassis Ground. The parasitic series inductance back to the power
supply is represented by L
1
. The voltage V
Z
on the line being protected is:
V
Z
= Forward voltage drop of D
1
+ L
1
x d(I
esd
)/dt + V
Supply
where I
esd
is the ESD current pulse, and V
Supply
is the positive supply voltage.
An ESD current pulse can rise from zero to its peak value in a very short time. As an example, a level 4 contact discharge
per the IEC 61000-4-2 standard results in a current pulse that rises from zero to 30 Amps in 1nS. Here d(I
esd
)/dt can be
approximated by
I
esd
/
t, or 30/(1x10
-9
). So just 10nH of series inductance (L
1
) will lead to a 300V increment in V
Z
!
