No suffix signifies a 10% tolerance, C signifies 2%. 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 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 I ZT. 4: Voltage measurements tobe performed 90 seconds after application of DC current. 5: RoHs Compliant already and Pb-free sticker on reel , box & carton indicated RoHs compliant .
