The type numbers shown have a 5% tolerance on nominal zener voltage. No suffix signifies a 10% tolerance, C signifies 2%, and D signifies 1% tolerance. 2. 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 dc Zener current (I ZT or IZK) is superimposed on I ZT. Zener impedance is measured at two points to insure a sharp knee on the breakdown curve and eliminate unstable units. o 3. The reverse surge current is measured at 25 C ambient using a ½ square wave or equivalent sine wave pulse 1/120 second duration superimposed on IZT. 4. Voltage at thermal equilibrium or 90 seconds after application of dc current.
