POLARITY: Diode to be operated with

the banded (cathode) end positive.

MOUNTING POSITION: Any.

NOTE 1

NOTE 2

Zener impedance is derived by superimposing on l

A 60Hz rms a.c. current

MOUNTING SURFACE SELECTION:

The Axial Coefficient of Expansion

(COE) Of this Device is Approximately

+6PPM/°C. The COE of the Mounting

Surface System Should Be Selected To

Provide A Suitable Match With This

Device.

equal to 10% of l

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.
