I think my message bounced.
Marv says that recovery time isn't important, based on the slow
slew rate of powerline frequencies.
What then makes sure the diodes all share equal voltages while
turing off? If it is junction capacitance, you are in trouble. The
capacitance is not only not matched, it changes with reverse
voltage. The lowest capacitance diode will turn off quickest, and
that will lower capacitance even more in that diode compared to
higher capacitance (slower) diodes.
Reverse leakage current, unless you take the diode to the
threshold, is extremely low. Are people claiming one diode goes to
threshold and then the others start being forced to threshold as
that single diode avalanches? Is that the mechanism that causes
voltages to be "shared"?
