CIRCUIT LAYOUT DATA:  
For Zener operation, cathode  
must be operated positive with  
respect to anode.  
NOTE 1  
Zener voltage range equals nominal voltage +5% for “A” Suffix types. No Suffix denotes + 10%.  
"C" suffix = + 2% and "D" suffix = + 1%.  
TOLERANCES: ALL  
Dimensions + 2 mils  
NOTE 2  
NOTE 3  
Zener voltage is read using a pulse measurement, 10 milliseconds maximum.  
Zener impedance is derived by superimposing on 1  
A 60Hz rms a.c. current equal  
ZT  
to 10% of 1
