1. Zener impedance is derived by superimposing on I_ZT at 60 HZ RMS AC current equal to 10% of I_ZT.
2. The maximum allowable change observed over the entire temperature range i.e., the diode voltage will not exceed the specialized mV at
any discrete temperature between the established limits, per JEDEC standard No.5.
