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 speci½ed mV at any discrete temperature between the established limits, per JEDEC standard No.5. Zener voltage range equals 8.5 volts + 5%.
