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 lZT A 60Hz rms

a.c. current equal to 10% of lZT.

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.

Zener voltage range equals 8.5 volts + 5%.
