For TVS diodes a low-ohmic and low-inductive path to chassis earth is absolutely mandatory in order to achieve good ESD

protection. Novices in the area of ESD protection should take following suggestions to heart:

Do not use stubs, but place the cathode of the TVS diode directly on the signal trace.

Do not make false economies and save copper for the ground connection.

Place via holes to ground as close as possible to the anode of the TVS diode.

Use as many via holes as possible for the ground connection.

Keep the length of via holes in mind! The longer the more inductance they will have.
