2) Reverse leakage current (IR)
Reverse leakage currents are guaranteed and measured at V R shown on the table.
3) Maximum zener current rating (IZM)
Maximum zener current ratings are based on maximum zener voltage of the individual units and
JEDEC 250mW rating.
4) Maximum voltage change (DVZ)
Voltage change is equal to the difference between VZat 100uA and at 10uA
