MOUNTING SURFACE SELECTION:
The Axial Coefficient of Expansion
(COE) Of this Device is Approximately
+6PPM/°C. The COE of the Mounting
Surface System Should Be Selected To
Provide A Suitable Match With This
Device.

NOTE 2
Zener impedance is derived by superimposing on l
equal to 10% of l
A 60Hz rms a.c. current
ZT
.
ZT
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 9.1 volts +5%
