Standard Zener voltage tolerance is 20%. Add suffix îš“Aîš”
for 10% tolerance and suffix îš“Bîš” for 5% tolerance.
Other tolerances, non standard and higher Zener voltages
upon request.

Notes:
(1) The Zener Impedance is derived from the 60Hz AC voltage which results when an AC current having an RMS value equal to 10% of the
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 to eliminate unstable units.
(2) Valid provided that leads at a distance of 8 mm from case are kept at ambient temperature.
(3) Measured under thermal equilibrium and DC test conditions.
