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 “A” suffix = + 5%, no suffix = +10%, "C" SUFFIX = + 2% and "D" suffix = + 1%.
NOTE 2 Zener impedance is derived by superimposing on l A 60Hz rms a.c. current
ZT
equal to 10% of l
or l
ZK.
ZT
NOTE 3 Nominal Zener voltage is measured with the device junction in thermal equilibrium
at an ambient temperature of 25°C + 3°C.
