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) Suffix "C" for 2% tolerance. Add suffix "A" for 5% tolerance. Other Zener voltages and tolerances are available upon request.
