Notes:
1. The type numbers listed have zener voltage as shown and have a standard tolerance on the nominal zener voltage of ±5%
in Blue marking, suffix A =±10% in Brown marking, C =±2% in Orange marking and D =±1% in Yellow marking.
2. The zener impedance is derived from the 60-cycle ac voltage, which results when an ac current having an rms value equal
to 10% of the dc zener current (I
ZT
or I
ZK
) is superimposed to I

or I
