CASE: DO-213AB, Hermetically sealed glass case. (MELF, LL41) LEAD FINISH: Tin / Lead THERMAL RESISTANCE: (ROJEC): 50 �C/W maximum = 0 inch THERMAL IMPEDANCE: (ZOJX): 15 �C/W maximum POLARITY: Diode to be operated with the banded (cathode) end positive. MOUNTING POSITION: Any.
No suffix + 10% tolerance on nominal Zener voltage, suffix "A" signifies +5%, "C" suffix signifies + 2% and "D" suffix signifies + 1%. Zener impedance is derived by superimposing A 60Hz rms a.c. current equal of 1ZT. Zener voltage is measured with the device junction in thermal equilibrium at an ambient temperature + 3�C.
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.
