POLARITY: Diode to be operated with

the banded (cathode) end positive.

MOUNTING POSITION: Any.

NOTE 1 Zener impedance is derived by superimposing on l

A 60Hz rms a.c. current equal to

10% of l

NOTE 2 The maximum allowable change observed over the entire temperature range i.e., the

diode voltage will not exceed the speci½ed mV at any discrete temperature between

the established limits, per JEDEC standard No.5.
