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