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.Double Anode: Electrical Specifications Apply Under Both Bias Polarities.
Zener impedance is derived by superimposing on lZT A 60Hz rms a.c. current equal 10% of lZT. The maximum allowable change observed over the entire temperature range i.e., the diode voltage will not exceed the specified mV at any discrete temperature between the established limits, per JEDEC standard No.5.
