DESIGN DATA

CASE:

Hermetically sealed glass

case. DO – 35 outline.

LEAD MATERIAL:

Copper clad steel.

LEAD FINISH:

Tin / Lead

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 .

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.

Zener voltage range equals 8.5 volts + 5%.
