DESIGN DATA
CASE: DO-213AA, Hermetically sealed glass case. (MELF, SOD-80, LL34) LEAD FINISH: Tin / Lead POLARITY: Diode to be operated with the banded (cathode) end positive. MOUNTING POSITION: Any. MOUNTING SURFACE SELECTION: The Axial Coefficient of Expansion (COE) Of this Device is Approximately +6PPM/°C. The COE of the Mounting Surface System Should Be Selected To Provide A Suitable Match With This Device.
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%
