Zener impedance is measured at two points to insur a sharp knee on the breakdown curve and to eliminate unstable units (2) Valid provided that leads at a distance of 10 mm from case are kept at ambient temperature (3) Standard Zener voltage tolerance is ± 10%. Add suffix “B” for ± 5% tolerance. Page 2 of 2 Rev. 03 : July 17, 2006
