Note 2. Zener Voltage (Vz) i s m easured w ith j unction i n t hermal e quilibrium w ith 3 0°C s tud temperature.
Note 3.The zener impedance is derived from the 60 cycle A.C. voltage, which results when an AC
current having an RMS value equal to 10% of the DC zener current (IZT or IZK) is superim-
posed on I ZT or IZK. Zener impedance is measured at 2 points to insure a sharp knee on the
breakdown curve and to eliminate unstable units.
