NOTE 2
Zener impedance is derived by superimposing on l
A 60Hz rms a.c.

CIRCUIT LAYOUT DATA:
Backside must be electrically
isolated.
Backside is not cathode.
For Zener operation cathode must
be operated positive with respect
to anode.
current equal to 10% of l
ZT.
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%.
