DESIGN DATA
CASE:
DO-213AA, Hermetically sealed
glass case. (MELF, SOD-80, LL34)
LEAD FINISH:
Tin / Lead
THERMAL RESISTANCE: (R
OJEC):
100 °C/W maximum at L = 0 inch
THERMAL IMPEDANCE: (Z
OJX): 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
1%.
“B” suffix = +5.0%, “A” suffix = +10%, no suffix = + 20%, "C" suffix = + 2% and "D" suffix = +
Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal to
10% of1ZT.
Nominal Zener voltage is measured with the device junction in thermal equilibrium at an
ambient temperature of 25°C + 3°C.
