You must have a means of measuring avalanche voltage at c. 2uA. In other
words, yu need a high-pot tester. . Diodes are typically graded into
drawers marked >800v, >900v, >1000v, >1100v, on and on. Diodes from the
same drawer are used to make a string.
- notes: I would discard any diode that has more than 1300 piv, shows
an erratic piv, or exhibits an erratic forward voltage drop at full rated
current.
