Notes: (1) Measured under thermal equilibrium and DC test conditions , Standard voltage tolerance is 10%,suffix B±5%
(2) The Zener impedance is derived from the 1KHZ 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 measure at two points to
insure a sharp knee on the breakdown curve and to eliminate unstable units
(3) Valid provided that electrodes at a distance of 10 mm from case are kept at ambient temperature
