IEEE Recommended Practice for Powering and Grounding Electronic Equipment - Redline
Regardless of the technology used, it is also important that there is some indication when a component of the surge suppressor has failed and is no longer protecting the load. SAD: The silicon avalanche diode has a very tight voltage clamp characteristic, a very fast response speed, but very low energy (surge current) capability.
