An electronic system protected against an incoming energy pulse, comprising a semiconductor device () connected in sequential order to a first impedance (), a coupling noise filter () having an internal frequency-dependent second impedance (), a third impedance (), a transient voltage suppressor (), a fourth impedance (), and an entry port exposed to the incoming energy pulse (). The fourth impedance has a size suitable for supporting the transient voltage suppressor in discharging a portion of the incoming energy pulse up to the full capability of the suppressor; the third impedance has a size suitable for supporting and synchronizing the performance of the coupling noise filter to filter common mode noise from two phase lags between differential signals; and the first impedance has a size suitable for diminishing, in combination with the second impedance as operational in the active frequency regime, the un-discharged portion of the energy pulse to a value under the device threshold failure current.
