FIGURE 1 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 lZT. 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.
