Rod Macpherson When using transient voltage suppressor (TVS) diodes for surge protection, particular care must be taken with PCB layout—especially the tracking between supply rails and the TVS device. For example, in systems with a 12 V rail and a separate 0 V reference (not chassis ground), a TVS diode may be placed between 12 V and 0 V to clamp surge events. In such cases, the routing to the TVS must not be implemented as a spur branching off the main power tracks. Spur con

On December 11th, we successfully organized our first EMC+SIPI Technical Discussion Group session. This is an exclusive, small community where members share hands-on experience and lessons learned in a trusted environment. The purpose of the group is to exchange ideas, enhance practical design expertise, and foster meaningful professional connections within a social and collaborative setting. Meeting notes from the session are shared below. If you are a Senior or Principal En
