POLARITY: Diode to be operated with
the banded (cathode) end positive.
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 All types are + 5% tolerance. VZ is measured with the Diode in thermal equilibrium
at 25°C + 3°C.
