APPLICATION NOTICE
Design advantage of ITAxxxB3 used with 4-point structure.
The ITAxxxB3 has been designed with a 4-point structure (separated Input/output) in order to efficiently
protect against disturbances with very high di/dt rates, such as ESD.
The purpose of this 4-point structure is to eliminate the overvoltage introduced by the parasitic inductances
of the wiring (Ldi/dt).
Efficient protection depends not only on the component itself, but also on the circuit layout.The drawing
given in figure shows the layout to be used in order to take advantage of the 4-point structure of the
ITAxxxB3.
With this layout, each line to be protected passes through the protection device.
In this way, it realizes an interface between the data line and the circuit to be protected, guaranteeing an
isolation between its inputs and outputs.
The 4 - point structure layout.
