Notes: 1. The device numbers listed have a standard tolerance on the nominal zener
voltage of
±5%.
2. For detailed information on price, availability and delivery of nominal zener
voltages between the voltages shown and tighter voltage tolerances.
3. The zener impedance is derived from the 60-cycle ac voltage, which results
when an ac current having an ms value equal to 10% of the dc zener current
(I
ZT
or I
ZK
) is superimposed to I
ZT
or I
ZK
.
