Put c. 50M ohms in series with one, connect it to a high-pot. Connect
the cathode of the diode stack to positive. Go slow. When you see a
*couple* of uA of reverse current, read the v. and STOP the test. This
is the piv at room temperature. At higher temperatures, the piv should
be derated roughly30%. However, for dx-peditions in hell, a 66.6%
derating is reportedly advisable.
