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. NOTE 2 The maximum allowable change observed over the entire temperature range, per JEDEC standard No.5. NOTE 3 Zener voltage range equals 12.8 volts + 5%.
