No suffix signifies a 10% tolerance, C signifies 2%, and D suffix 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(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. o 3: The reverse surge current is measured at 25 C ambient using a 1/2 square wave or equivalent sine wave pulse 1/120 second duration superimposed on IZT. 4: Voltage measurements tobe performed 90 seconds after application of DC current. www.mccsemi.com Version: 3 2003/01/22 MCC 1N4728 thru 1N4764 Ratings and Characteristic Curves (T A = 25°C unless otherwise noted) 1N4728 ... 1N4764 www.mccsemi.com Version: 3 2003/01/22
