. Units with “A”
suffix are ±10% with guaranteed limits for V
Z
, I

):
35°C/W maximum
NOTE 2: Zener voltage is measured with the device junction in thermal equilibrium at an ambient
temperature of 25°C ± 3°C.
POLARITY: Diode to be operated with the banded
(cathode) end positive.
NOTE 3: Zener impedance is derived by superimposing on I
ZT
A 60Hz rms a.c. current equal to 10% of I
ZT
.
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 4: Reverse leakage currents are measured at V
R
as shown on the table.
NOTE 5: ∆
∆∆
∆V
Z
is the maximum difference between V
