In the low Zener current region the Zener voltage will become unstable due to the effects of noise during Zener breakdown. This will result in variations in the internal impedance, leading to Zener voltage fluctuations. Therefore, we recommend a Zener current Iz greater than 1mA in order to ensure stable operation.
