Notes:
1. The type numbers listed have zener voltage as shown and have a standard
tolerance on the nominal zener voltae of
±5%
in Blue marking, suffix A=±10%
in Orange marking and D=±1% in Yellow marking.
2. For detailed information on price, availability and deliver 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
.
