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: (ZJX): 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
The CDI type numbers shown above have a Zener voltage tolerance of +5.0%. Nominal Zener voltage is measured with the device junction in thermal equilibrium at an ambient temperature of 25C + 3C. "C" suffix denotes a + 2% tolerance and "D" suffix denotes a + 1% tolerance. Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal to 10% of IZT.
