NOTE 1
Zener voltage range equals nominal Zener voltage + 5% for no suffix types.
Zener voltage is read using a pulse measurement, 10 milliseconds maximum.
"C" suffix = + 2% tolerance and "D" suffix = + 1% tolerance.
NOTE 2
Zener impedance is derived by superimposing on lZT A
60Hz rms a.c. current equal to 10% of lZT.

Back: (Cathode)............. ..Au
CIRCUIT LAYOUT DATA:
For Zener operation, cathode
must be operated positive with
respect to anode.
