I am using the DIODE ARRAY ESD 3.3V IC for protection and here is the datasheet of it http://www.nxp.com/documents/data_sheet/pesdxs4ud_ser.pdf

the card we design has 128 point need protection so we use 44 ICs, each one of them is used to protect 3 points Bidirectional

there is no enough space for more ICs..

what should I do??

remove these ICs and put diodes or what??
