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
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.
Zener impedance is derived by superimposing on lZT A 60Hz rms a.c. current
equal to 10% of lZT.
