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
.
