I'm currently trying to ESD protect a design I'm working on by using TVS diodes. I'm placing these diodes on user interface components (pushbuttons, switches, exposed pins, etc.).
In the process of doing this, I had placed a TVS diode parallel to an IC's power pin, where I had also previously placed a decoupling capacitor. Because the voltage across a capactior can't change instantaneously, I'm curious if any ESD would just be filtered by the cap.
Question: Do decoupling capacitors offer ESD protection?
