Measured under thermal equilibrium and dc (IZT) test conditions. 4. The Zener impedance is derived from the 60 Hz ac voltage which results when an ac current having an rms value equal to 10% of the Zener current (IZT or IZK) is superimposed on IZT or IZK. Zener impedance is measured at two points to insure a sharp knee on the breakdown curve and to eliminate unstable units. Electrical Characteristics @ TA = 25°C unless otherwise specified

Notes: 5. *Add "-A" or "-T" to the appropriate type number in Table 1. Example: 6.2V Zener = 1N4735A-A for ammo pack. 6.
