Adapting Diode triggered SCRs (part 2)
In this article, I wish to introduce you to how we can use diode triggered silicon controlled rectifiers (DTSCRs) for on-chip ESD protection. I will explain how its 3 main parameters – trigger voltage, holding voltage and failure current – can be tuned in order to protect ICs with very different characteristics.
