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%.
