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 L1. The voltage VZ on the line being protected is:
VZ = Forward voltage drop of D1 + L1 x d(Iesd)/dt + VSupply
where Iesd is the ESD current pulse, and VSupply 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(Iesd)/dt can be
approximated by Iesd/t, or 30/(1x10-9). So just 10nH of series inductance (L1) will lead to a 300V increment in VZ!
