One more question !!!
If I trying to withstand 25 kV impulse into DUT (device under test), 2 second per period, 10 times, non-dischage, with load by 12V, have any concern need to take care about the PCB layout ? How about the copper strip width and distance ? can add a surge protector (such as Epcos T230-350X) between the circuit or not ?
Best regards,
Nicco
