SILICON PLANAR ZENER DIODES
Standard Zener voltage tolerance is ± 20%.
Add suffix "A" for ± 10% Tolerance, suffix
"B" for ± 5% tolerance, suffix "C" for ± 2%
tolerance, Other tolerance, non standard
and higher Zener voltages are upon request.

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.
