| 1. A system for protecting an electronic device from an electrical event, comprising:
first and second leads adapted for passing an electric current through an electronic device;
a second diode protection mechanism coupled in series with the electronic device when the leads are coupled to the electronic
device; and
a first diode protection mechanism coupled to the leads such that the first diode protection mechanism is connected in parallel
with the electronic device and the second diode protection mechanism when the leads are coupled to the electronic device,
wherein at least one of the diode protection mechanisms contains multiple sets of diodes, the sets of diodes in the at least
one of the diode protection mechanisms being arranged in parallel with one another, each set of diodes comprising at least
two diodes.
