NOTE 1 Zener impedance is derived by superimposing on lZT @ 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 speciï¬ed mV at any discrete
temperature between the established limits, per JEDEC standard No. 5.
