NOTE:

1.Tolera nce and T ype Number Designation. The type numbers listed have a standard tolera nce on the nominal zener voltage of ±5%.

2.Specials Available Include:
A. Nominal zener voltages between the voltages shown a nd tighter voltage tolerances.
B. Matched sets.

3.Zener Voltage (VZ) Measurement. Guara ntees the zener voltage when mea sured at 90 seconds while maintaining the lead temperature (TL) at 30OC, from the diode body.

4.Zener Impedance (ZZ) 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 (IZT or IZK) is superimposed on IZT or IZK.

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, IZT, per JEDEC registration; however, a ctual device ca pability is a s described in Figure 5.
