ELECTRICAL CHARACTERISTICS (TA=25OC unless otherwise noted) VF=1.2V max, IF=100mA for all type s.
NOTE:
1.T olerance and Type 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 and tighter voltage tolera nces.
B. Matched sets.
3.Zener Voltage (VZ) Mea surement. Guarantees the zener voltage when me asured at 90 seconds while maintaining the lea d 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 superi mposed 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 superi mposed on the test current, IZT, per JEDEC registration; however , a ctual device ca pability is a s described in Figure 5.
