Abstract

The present technology relates to circuitry immunity to electrical interference, such as Electrical Fast Transient (EFT) interference. In an example embodiment, an interference dissipation circuit is provided. The interference dissipation circuit includes a transient voltage suppression (TVS) sub-circuit, a ferrite bead having a first terminal and a second terminal, a capacitor coupled in series with the ferrite bead and having a first terminal and a second terminal. The TVS sub-circuit includes a plurality of TVS ports, and the TVS sub-circuit is coupled to the set of output ports at a first set of TVS ports of the plurality of TVS ports. The ferrite bead is coupled to a ground port of the plurality of TVS ports, the second terminal of the ferrite bead is coupled to the first terminal of the capacitor, and the second terminal of the capacitor is coupled to a chassis in an industrial automation environment.
