NOTE 1
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.
NOTE 2
Zener impedance is derived by superimposing on l
ZT
A 60Hz rms a.c. current
equal to 10% of l
ZT
