FIGURE 1
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 lZTA
60Hz rms a.c. current equal to 10% of lZT.
