Notes: Zener impedance derived from 1KHZ voltage which results when current having value equal Zener current (IZT IZK) superimposed IZK. Zener impedance measured points insure sharp knee breakdown curve eliminate unstable units Valid provided that electrodes distance 10mm from case kept ambient temperature type number listed have standard tolerance nominal zener voltage 10%.
