POWER DERATING CURVE

NOTE 1

Zener voltage range equals nominal Zener voltage + 5%.

NOTE 2

Zener impedance is derived by superimposing on l

ZT

A 60Hz rms a.c. current

equal to 10% of l

ZT

.

NOTE 3

The “maximum millivolt change” (see Table) is the maximum allowable change

observed over the entire temperature range, per JEDEC standard No.5.
