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  
NOTE 2  
NOTE 3  
Zener voltage tolerance on "B" suffix is + 5%. Suffix letter “A” denotes + 10%. No  
Suffix denotes + 20%. "C" suffix denotes + 2%, and "D" suffix denotes + 1%.  
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  
ZT  
to 10% of 1
