Note 1: The JEDEC type number shown with an A suffix have a 5% tolerance on nominal zener voltage. 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(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.
3: The reverse surge current is measured at 25oC 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.
5: RoHs Compliant already and Pb-free sticker on reel , box & carton indicated RoHs compliant .
