Hi Forum.
I need a very fast surge protection on a power line feeding a LED driver at 24 volts. The system was tested under IEC 61000-4-x specifications and failed on pulse disturbance induced on the power cable.
A TVS diode was added (1.5KE33), but maybe it was not fast enough. The test pulses induced are in ns level.
My next actions include a ferrite ring on both the power cables and a faster TVS after them.
Any other suggestions for faster TVS or other kind of protection please?
Thanks,
Ioannis
