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.
NOTE 3
Zener voltage range equals 9.0 volts + 5%.
