2. TOLERANCE AND TYPE NUMBER DESIGNATION (V
Z
)
The type numbers listed have a standard tolerance on the nominal zener voltage of
±5%.
3. ZENER VOLTAGE (VZ) MEASUREMENT
Nominal 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 CURREN (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 (∆V
Z
)
Voltage change is equal to the difference between V
Z
at 100uA and at 10uA.
