NOTE 1

Zener impedance is derived by superimposing on lZTA 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 specified mV at any discrete temperature

between the established limits, per JEDEC standard No.5.
