2.
TOLERANCE AND TYPE NUMBER DESIGNATION (V
Z
)
The type numbers listed have a standard tolerance of
±5%
on the nominal zener voltage.
3.
ZENER VOLTAGE (V
Z
) MEASUREMENT
The zener voltage is measured with the device junction in the thermal equilibrium at the lead temperature (T
L
) at 30°C
±
1°C and 3/8″ lead
length.
4.
REVERSE LEAKAGE CURRENT (I
R
)
Reverse leakage currents are guaranteed and measured at V
R
shown on the table.
5.
MAXIMUM ZENER CURRENT RATINGS (I
ZM
)
Maximum zener current ratings are based on maximum zener voltage of the individual units and JEDEC 250 mW rating.
6.
MAXIMUM VOLTAGE CHANGE (DV
Z
)
Voltage change is equal to the difference between V
Z
at 100
mA
and at 10
mA.
