POLARITY: Diode to be operated with
the banded (cathode) end positive.
† Double Anode: Electrical Specifications Apply Under Both Bias Polarities.
NOTE 1
Zener impedance is derived by superimposing on l A 60Hz rms a.c. current equal
ZT
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.
DESIGN DATA
CASE: Hermetically sealed glass
case. DO – 35 outline.
LEAD MATERIAL: Copper clad steel.
MOUNTING POSITION: Any.
