Re: Interupting xenon flash current ?

I believe there is a mistake with your measurement. In the common cameras, the flash current is at the order of 100A and the duration is ~tens of milliseconds. They handle it with IGBT of SOT-223 form factor.

That was my frst reaction also since I expected to see something less than 400A, but I can't find any reason
for such a major error.

I bet it is either inductive or capacitive parasitic pickup or a common ground problem.
