Zener Voltage (Vz) is measured with junction in thermal equilibrium with 30C stud 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 superimposed on IZT or IZK. Zener impedance is measured at 2 points to insure a sharp knee on the breakdown curve and to eliminate unstable units. .687 (17.4) .667 (16.9) Dia .375 (9.55) 1.440 (36.58) .450 (11.4) .453 (11.5) .150 (3.81) Dia .200 (5.08) 1/4−28 UNF−2A
