Day 9: ESD Protection Diodes

I took the weekend off but we're back today. My schedule may prevent me from posting daily but I'll keep putting things up when I have time. Today I look at something that I've seen quite a bit as an intern in the protection division at ON Semi.

I love how simple yet so genius this configuration is. So many things we plug into the wall have this in it; there must be zillions of these out there.
