= 200 mA for all types
Notes:
1. The type numbers listed have zener voltage min/max limits as shown and have a standard tolerance on the nominal zener
voltage of 5%.
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
