+10% tolerance, suffix “B” for +5% tolerance and suffix “C” for
+2% tolerance. Other tolerance, non standard and higher Zener

1) 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 Zener current (I
ZT
or I
ZK
) is superimposed on I
ZT
or I
ZK
. 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 electrodes are kept at ambient temperature.
3) Measured under thermal equilibrium and DC test conditions.
4) Tested with pulses tp = 20 ms.
