Note 1
Devices listed have a
±
5% tolerance on nominal V
Z.
The suffix
A
denotes a
±
20% tolerance,suffix
C
denotes a
±
2%
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.
Note 5
MCC
TM
Micro Commercial Components
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
).
Note 7
Note 4
The Maximum Reverse (leakage) Current is specified
for devices with
±
20% and
±
10% voltage tolerances
on nominal V
Z
in another column.

*** Data of Figure 3 should not be used to compute surge capability. Surge limitations are given in Figure 5. They are
lower than would be expected by considering only junction temperature, as current crowding effects cause
temperatures to be extremely high in small spots resulting in device degradation should the limits of Figure. 5 be
exceeded
