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 Speci½cations Apply Under Both Bias Polarities.
NOTE 1 Zener impedance is derived by superimposing on l
ZT
A 60Hz rms a.c. current equal
to 10% of l
ZT
.
NOTE 2 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.
