Notes
(1) Tolerancing and voltage designation (V ). The type numbers shown have a standard tolerance of ± 5 % on the nominal zener voltage.
Z
(2) Maximum Zener current ratings (I ). Maximum Zener current ratings are based on maximum Zener voltage of the individual units
ZM
(3) Reverse leakage current (I ). Reverse leakage currents are guaranteed and measured at V as shown on the table.
R
R
(4) Maximum voltage change (ΔV ). Voltage change is equal to the difference between V at 100 μA and V at 10 μA.
