Zener impedance is measured at two points to insure a sharp knee on the breakdown curve and to eliminate unstable units (2) Valid provided that electrodes at a distance of 10mm from case are kept at ambient temperature (3) Measured under thermal equilibrium and DC test conditions. (4) Standard Zener voltage tolerance is ± 10% tolerance. Other Zener voltages and tolerances are available upon request. Page 2 of 2 Rev. 03 : March 25, 2005
