I am tracing the circuit of a computer power supply unit (PSU), it blew up and I'm trying to discover why.
It has 2 identical components that I can't identify.
The attached photo, shows the PSU label with one of the components laying on it.
As you can see, it has SUM1-PA printed on it. They are designated V1 & V2 on the PCB.
Their position in the circuit makes me assume that they are voltage spike suppressors.
I did an internet search for a data sheet but no result.
Does anyone know what it is?
Any advice will be appreciated.
