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 speci½ed mV at any discrete temperature
between the established limits, per JEDEC standard No.5.
.
NOTE 3 Zener voltage range equals 8.5 volts +
