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.
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 specified mV at any discrete
temperature between the established limits, per JEDEC standard No.5.
NOTE 2
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.
