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.
NOTE 3
Zener voltage range equals 9.1 volts +5%
