induced line transients. The MAX3202E/MAX3203E/
MAX3204E/MAX3206E clamp to 100V; however, with
improper layout, the voltage spike at the device is
much higher. A lead inductance of 10nH with a 45A
current spike at a dv/dt of 1ns results in an ADDITION-
AL 450V spike on the protected line. It is essential that
the layout of the PC board follows these guidelines:
1) Minimize trace length between the connector or
Figure 6. IEC 61000-4-2 ESD Test Model
IEC 61000-4-2
The IEC 61000-4-2 standard covers ESD testing and
performance of finished equipment. The MAX3202E/
MAX3203E/MAX3204E/MAX3206E help users design
equipment that meets Level 4 of IEC 61000-4-2.
The main difference between tests done using the
Human Body Model and IEC 61000-4-2 is higher peak
current in IEC 61000-4-2. Because series resistance is
lower in the IEC 61000-4-2 ESD test model (Figure 6)
the ESD-withstand voltage measured to this standard is
generally lower than that measured using the Human
Body Model. Figure 3 shows the current waveform for
the ±8kV IEC 61000-4-2 Level 4 ESD Contact
Discharge test.
input terminal, I/O_, and the protected signal line.
2) Use separate planes for power and ground to reduce
parasitic inductance and to reduce the impedance to
the power rails for shunted ESD current.
3) Ensure short ESD transient return paths to GND
and V CC .
4) Minimize conductive power and ground loops.
5) Do not place critical signals near the edge of the
PC board.
6) Bypass V CC to GND with a low-ESR ceramic capac-
itor as close to V CC as possible.
7) Bypass the supply of the protected device to GND
with a low-ESR ceramic capacitor as close to the
supply pin as possible.
