DESIGN DATA
CASE: DO-213AA, Hermetically sealed glass case. (MELF, SOD-80, LL34) LEAD FINISH: Tin / Lead THERMAL RESISTANCE: (ROJEC): 100 C/W maximum at L = 0 inch THERMAL IMPEDANCE: (ZOJX): 35 C/W maximum POLARITY: Diode to be operated with the banded (cathode) end positive. 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 All types are + 5% tolerance. VZ is measured with the Diode in thermal equilibrium at 25C + 3C. NOTE 2 VZ @ 100 A minus VZ @ 10A.
