NOTE:
3. Zener Voltage (V
Z
) Measurement. Guarantees the zener voltage when measured at 90 seconds while maintaining
the lead temperature (T
L
) at 30°C ± 1°C, from the diode body.

4. Zener Impedance (Z
Z
) Derivation. The zener impedance is derived from the 60 cycle ac voltage, which results when
an ac current having an rms value equal to 10% of the dc zener current (I

or I
ZK
) is superimposed on I
ZT

1. Tolerance and Type Number Designation. The type numbers listed have a standard tolerance on the nominal zener
voltage of ± 5%.
2. Specials Available Include:
A. Nominal zener voltages between the voltages shown and tighter voltage tolerances.
is as described in Figure 5.
5. Surge Current (Ir) Non-Repetitive. The rating listed in the electrical characteristics table is maximum peak,
non-repetitive, reverse surge current of 1/2 square wave or equivalent sine wave pulse of 1/120 second
duration superimposed on the test current, I
