**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%, and D suffix signifies 1% tolerance. 

- 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. 

- 3: The reverse surge current is measured at 25[o] 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 .
