= 100mA for all types.
Notes : 1. The type numbers listed have zener voltage min/max limits as shown.
2. The zener impedance is derived from the 60-cycle ac voltage, which results when an ac current
having an rams value equal to 10% of the dc zener current
(I
zt
or I
zk
) is superimposed to I
zt
or I

.
