No suffix signifies A 10% tolerance, C signifies 2%, and D signifies 1% tolerance. NOTE 2 The zener impedance is derived from the 60Hz AC 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 two points to insure a sharp knee on the breakdown curve and eliminate unstable units. NOTE 3 The reverse surge current is measured at 25oC 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. www.mccsemi.com MAXIMUM SURGE CURRENT IS mA 1380 1260 1190 1070 970 890 810 730 660 605 550 500 454 414 380 344 304 285 250 225 205 190 170 150 135 125 115 110 95 90 80 70 65 60 55 50 45
