DESIGN DATA
CASE:
DO-213AA, Hermetically sealed
glass case. (MELF, SOD-80, LL34)
LEAD FINISH:
Tin / Lead
POLARITY:
Diode to be operated with
the banded (cathode) end positive.
MOUNTING POSITION:
Any.
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 1
Zener impedance is derived by superimposing on lZT A 60Hz rms a.c. current
equal to 10% of lZT.
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.
Zener voltage range equals 9.1 volts +5%
