POWER DERATING CURVE
NOTE 1 Zener voltage range equals nominal Zener voltage + 5%.
NOTE 2 Zener impedance is derived by superimposing on lZT A 60Hz rms a.c. current
equal to 10% of lZT.
NOTE 3 The “maximum millivolt change” (see Table) is the maximum allowable change
observed over the entire temperature range, per JEDEC standard No.5.
