NOTE 1 Zener impedance is derived by superimposing on lZT A 60Hz rms a.c. current equal to
10% of lZT.
NOTE 2 The maximum allowable change observed over the entire temperature range i.e., the
diode voltage will not exceed the speci½ed mV at any discrete temperature between
the established limits, per JEDEC standard No.5.
