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 orI ) is superimposed on I orI . Zener ZT ZK ZT ZK impedance is measured at two points to insure a sharp knee on the breakdown curve and eliminate unstable units. 3: The reverse surge current is measured at 25oC ambient using a 1/2square 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 . wwwm. ccsem.ciom Revision: A 2 of 4 2011/01/01
