Note:
1) Tolerance and type number designation (V
Z
)
The type numbers listed have a standard tolerance of ±5% on the nominal zener voltage.C for
2% , D for 1%
2) 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
O
C ± 1
O
C and 3/8” lead length.
3) Reverse leakage current (I
R
)
Reverse leakage currents are guaranteed and measured at V
R
shown on the table.
4) Maximum zener current rating (IZM)
Maximum zener current ratings are based on maximum zener voltage of the individual units
and JEDEC 250mW rating.
5) Maximum voltage change ( V
Z
)
Voltage change is equal to the difference between V
Z
at 100uA and at 10uA
