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