POLARITY: Diode to be operated with  
the banded (cathode) end positive.  
NOTE 1  
NOTE 2  
NOTE 3  
Zener voltage tolerance on "B"suffix is + 5%. Suffix letter A denotes +10%. No Suffix  
denotes + 20% tolerance, "C" suffix denotes + 2% and "D" suffix denotes + 1%.  
MOUNTING POSITION: Any.  
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  
ZT  
equal to 10% of 1
