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.

† Double Anode: Electrical Specifications Apply Under Both Bias Polarities.

NOTE 1 Zener impedance is derived by superimposing on lZTA 60Hz rms a.c. current equal

to 10% of lZT.

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.
