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
JX): 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
Zener voltage tolerance on "B" suffix is + 5%. Suffix letter “A” denotes + 10%. No
Suffix denotes + 20%. "C" suffix denotes + 2%, and "D" suffix denotes + 1%.
Zener voltage is measured with the device junction in thermal equilibrium at an ambient
temperature of 25°C + 3°C.
Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal
to 10% of 1ZT.
