Note 1
Devices listed have a
±
5% tolerance on nominal V
Z.
The suffix A denotes a
±
20% tolerance, suffix C
denotes
±
2%, and suffix D denotes
±
1%.
Nominal Zener Voltage (V
Z
) is read with the device in
standard test clips with 3/8 to ½ inch spacing between
clip and case of the diode. Before reading, the diode is
allowed so stabilize for a period of 40
±
10 milliseconds
at 25°C (+8, -2°C).
The Zener impedance (Z
ZT
or Z
ZK
is derived from the 60
H
Z
ac voltage, which results when an ac current having
a rms value equal to 10% of the dc zener current (I
ZT
or
I
ZK
) is superimposed on I
ZT
or I
ZK
respectively. Dynamic
impedance variations with other current values are
described in Micronote 202.
The Maximum Reverse (leakage) Current is specified
for devices with
±
20% and
±
10% voltage tolerances
on nominal V
Z
in another column.
Note 5
The Maximum Zener Current (I
ZM
) shown is for
±
5%
tolerance devices. I
ZM
for
±
10% and
±
20% devices
can be calculated using the formula:
I
ZM
=
P
V
ZM
Note 2
Where “V
ZM
” is V
Z
at the high end of the voltage
tolerance specified and “P” is the rated power of the
device.
Note 3
Note 6
The Surge Current (I
ZM
) is specified as the maximum
peak of a nonrecurring sine wave of 8.3 milliseconds
duration.
Voltage Regulation (
∆V
Z
) is the difference between the
voltage measured at 10% and 50% I
ZM
).
