DO - 35 outline. LEAD MATERIAL: Copper clad steel. LEAD FINISH: Tin / Lead POLARITY: Diode to be operated with the banded (cathode) end positive. 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 speci1/2ed mV at any discrete temperature between the established limits, per JEDEC standard No.5. MOUNTING POSITION: ANY.
