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
ZT
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 specified mV at any discrete temperature between
the established limits, per JEDEC standard No. 5.
