TOLERANCE AND VOLTAGE DESIGNATION: The type part numbers shown are +/- 20 % with guaranteed limits for only V
Z
, I
R
and
V
F
. Units with A suffix are +/- 10% with guaranteed limits for only 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%.
ZENER (V
Z
) VOLTAGE MEASUREMENT: Nominal zener voltage is measured with the device junction in thermal equilibrium with
ambient temperature of 25°C at the specified current of I
ZT
.
ZENER IMPEDANCE (Z
Z
) DERIVATION: The zener impedance is derived from the 60 Hz voltage, which results when an ac current
having an rms value equal to 10% of the dc zener current (I
ZT
) is superimposed on I
ZT
.
REVERSE LEAKAGE CURRENT (I
R
):
Reverse leakage current is guaranteed and measured at V
R
as shown on the table.
MAXIMUM REGULATOR CURRENT (I
ZM
): The maximum current shown is based on the maximum voltage of a 5.0% type unit;
therefore, it applies only to the B C, or D suffix devices. The actual I
ZM
for any devices may not exceed the value of 200 milliwatts
divided by the actual V
Z
of the device.
MAXIMUM REGULATION FACTOR (? V
Z
): ? V
Z
is the maximum difference between Vz at I
ZT
and V
Z
at I
ZL
measured with the device
junction in thermal equilibrium.
