Notes:
1. The zener voltage (V
Z
) is tested under pulse condiciton of 15mS. The measured V
Z
is guaranteed to be within specification with device junction in thermal equilibrium.
2. The device numbers listed have a standard tolerance on the nominal zener
zener voltage of
±5%.
3. The zener impedance is derived from the 60-cycle ac voltage, which results when an
ac current having and ms value equal to 10% of the dc zener current (I
ZT
or I
ZK
)
is superimposed to I
ZT
or I
ZK
.
4. For detailed information on price, availability and delivery of nominal zener voltages
between the voltages shown and tighter voltage tolerances.
