Hi,
We are facing problem to make our board get passed in the EFT testing. The same circuit is used in many PCBs which passed the test standard.
But, in the present board, we couldn't. For the protection we used only one bipolar TVS diode and there is no ferrite bead or resistor in that path.
Please help me by providing few design tips, equations and PCB routing tips for designing the EFT protection circuit so that the next revision of our board will pass the test.
Thanking you,
