NOTE 1 Zener impedance is derived by superimposing on l

ZT

A 60Hz rms a.c. current equal to

10% of l

ZT

.

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.
