The JEDEC type numbers shown with an A suffix have a 5% tolerance on nominal zener voltage. No suffix signifies a 10% tolerance, C signifies 2%, and D suffix signifies 1% tolerance. NOTE 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 (IzT or !zK) is superimposed on Izt or Izk. Zener impedance is measured at two points to insure a sharp knee on the breakdown curve and eliminate unstable units. NOTE 3. The reverse surge current is measured at 25C ambient using a 1/2 square wave or equivalent sine wave pulse 1/120 second duration superimposed on IzT. NOTE 4. Voltage measurements to be performed 90 seconds after application of DC current.
