Hi there,

I am trying to make my design a bit more resilient by adding ESD protection to the VGA output.

The best I could find was the SMS05C like https://www.mouser.de/ProductDetail/Sem ... IgbA%3D%3D
It has 5 protection diodes in a single package, just good for VGA RGB an H/V-sync.

However it's not totally VGA spec (~1V on RGB) but that does not affect my circuit. And I haven't in fact seen any ESD protection circuit for discrete VGA output circuits ...

So, what's your take, is that IC a good choice?

Thanks
André

PS I might even use it for USB even if there are only two lines needed...

What's an additional VIA among friends, anyhow?

It's for this VGA output circuit. I thought I'd at least have it there as an option.

I haven't had any damage plugging VGA myself, and mostly heard about the - NMOS - joystick ports of the C64 being damaged. But that may just be because of the protection circuit in the VGA path
