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
NOTE 3
Zener voltage is measured with the device junction in thermal equilibrium at an ambient
temperature of 25°C + 3°C.
Zener impedance is derived by superimposing on 1 A 60Hz rms a.c. current equal to
ZT
10% of1
