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 l ZT A 60Hz rms a.c. current equal to 10% of l ZT. NOTE 2 The maximum allowable change observed over the entire temperature range i.e., the diode voltage will not exceed the specified m V at any discrete temperature between the established limits, per JEDEC standard No. 5.
