1: Vz: tolerance +/-5%
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 .
