The operation of electric motors and other inductive loads in the electric system of an aircraft induces high energy transients that tend to damage the transistors and other semiconductors in the aircraft's avionic equipment. These damaging effects are cumulative and tend to reduce the effective life of such components. Such transients may have peak values of hundreds of volts and several amperes of current. An energy absorbing device in the form of a reverse-characteristic diode is connected in series with a fuse, and the series combination is connected between the power bus and ground. This diode conducts at high transient voltages and effectively absorbs the energy of such transients and diverts the damaging effects thereof from the avionic semiconductors.
