IZT IZM (2) ΔVZ (4) IR (3) at VR (V) (V) (V) (µA) (mA) (V) (μA) (V) Notes : (1) The type number shown have a standard tolerance of ± 5% on the nominal zener voltage . (2) Maximum zener current ratings are based on maximum zener voltage of the individual unit. (3) Reverse leakage current are guaranteed and measured at V R as shown on the table . (4) Voltage change is equal to the difference between V Z at 100 µA and VZ at 10 µA. Page 2 of 2 Rev. 00 : November 14, 2008 Zener Voltage VZ @ IZTType www.eicsemi.com
