Zener impedance is measured at two points to insure a sharp knee on the breakdown curve and eliminate unstable : The reverse surge current is measured at 25oC ambient using a 1/2 square wave or equivalent sinewave pulse 1/120 second duration superimposed on : Voltage measurements tobe performed 90 seconds after application of DC : RoHs Compliant already and Pb-free sticker on reel , box & carton indicated RoHs compliant .
