DESIGN DATA
CASE:
DO-213AA, Hermetically sealed glass case.
(MELF, SOD-80, LL34)
LEAD FINISH:
Tin / Lead
THERMAL RESISTANCE: (R
θ
JEC
):
100 °C/W maximum at L = 0 inch
THERMAL IMPEDANCE: (Z
θ
JX
):
35°C/W maximum
POLARITY:
Diode to be operated with the banded
(cathode) end positive.
MOUTING 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: No Suffix type numbers are ±20% with guaranteed limits for only V
Z
, I
R
, and V
F
. Units with “A”
suffix are ±10% with guaranteed limits for V
Z
, I
R
, and V
F
. Units with guaranteed limits for all six
parameters are indicated by a “B” suffix for ±5.0% units, “C” suffix for ±2.0% and “D” suffix for
±1.0%.
NOTE 2: Zener voltage is measured with the device junction in thermal equilibrium at an ambient
temperature of 25°C ± 3°C.
NOTE 3: Zener impedance is derived by superimposing on I
ZT
A 60Hz rms a.c. current equal to 10% of I
ZT
.
NOTE 4: Reverse leakage currents are measured at V
R
as shown on the table.
NOTE 5:
∆
V
Z
is the maximum difference between V
Z
at I
ZT
and V
Z
at I
ZL
measured with the device junction
in thermal equilibrium.
