Electrical Characteristics (Tamb = 25 ° unless otherwise noted)
Maximum VF = 0.9 V at IF = 10 mA
1)The Zener Impedance is derived from the 1 kHZ 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.
3) Measured at thermal equilibrium.
